Bro you explain stuff perfect and my 72 Buick Skylark literally started bogging out at 30 miles an hour like it was getting too much fuel what's your thoughts Could It Be Me screwing with the front needle adjustment too much out of whack or timing too far advanced
I have a 1971 ford thunderbird my car is doing the same thing when I change my coil it fired up drove it all that day I parked it for a couple of days went to try to start it no start
I've replaced modules, pick ups, breaker plates , you know stumbling around not knowing how I fixed it, but I got pretty good at doing what I didn't know. You've made it make sense to where I can at least understand it as much as a person like myself understands anything. It might not be clear as day to me , but at least it's not a dense fog. Thanks for doing the public a good service. You the man.
people overcomplicate everything.... sometimes intentionally, sometimes people are taught by, well, not every dr is good dr, not every mechanic is good mechanic, every teacher is not there because they love to teach, most teachers or dr's or lawyers or mechanics are just there for a pay check, and they only know enough to get by......... a big help was, my auto teacher in high school made us draw every part. it didnt have to be to scale, but it had to work, every jet passage or every hydro passage on a master, what ever it was, every bearing every ring it had to work.
Nice! I wasn't even looking for help like this. I was looking how to wire a coil in a 76 vw 1600. I watched the whole video because of the way you were explaining everything that could be wrong. Good freaking job!!!
@10xH . A lot of guys DIY watch videos to get an idea how tough it will be. I'm not good at diagnostics so when you showed and explaind all the things that could be bad, I t helps with that decision. Plus the calm and methodical way you presented yourself.
I want to sincerely thank you for this video. I have been catching hell trying to get my Charger to start after letting it sit over a year. I had it in my mind that it was the fuel pump. Then I was thinking I didn't install it right. Could not get it to start. Was thinking of replacing the distributor, ignition module.. etc.. just guessing. Your video DID THE TRICK! I ohmed out the coil just like you showed and compared it to two other coils (one brand new) and that was the issue. That 440 is running like a champ now. I cannot thank you enough.
MY 77 F350 always starts up. today no crank and nothing. was about to call a mechanic to come check it out. saw your vid. did the steps and everything was working until i switched the ignition module. started up instantly. thank you sir. Thanks to you, i learned something new today.
This guy is one of the best they are around as far as explaining and showing you a video on a like this it would be very easy to work on anything after watching his video thanks Tracy Davis
They man thanks my 1969 Charger 440 magnun, worked well, parked it the garage, all of a sudden no spark, with your video checked the coil with the volt meter, it was bad, swapped it out now back to normal. Cheers awesone dude, saved me a ton of money. Great respescts from Canada
lol my great grandpa snuck in here from Canada as a flying trapeze in the circus, they should have built a wall. buahhhhh. Im not left or right, all I can say is, bush got elected said he was gonna build an electric fence, the only place they didnt do the fence and monitor system was in the only two places you could actually swim across the river..... Then trump in 2002 on Tv was asked why he dropped out the race, he said he wasn't gonna beat bush. he was asked when will we finally have a Libertarian president, he said when their ready for me. and I quote "George bush went on Fox News, said he was gonna build a fence, got all the redneck votes, so im gonna go on fox as a republican and say im going to build a wall". sheeple!
Thanks for the effort you put into this video! Took my 76 Ford dump truck to the mechanic but every one of them in town is to lazy to diagnose like this. They just say to run it until it won't then bring it in. If you want it done right sometimes you have to do it your self.
Got the one on pertronix and vacuum gauge power tuning is part two. A vacuume gauge will.tell.you most mechanical issues. The next one in putting out is on a leak down test. A leak down test.is the only way to pinpoint / prove any mechanical issue before proceeding and not just guessing but nobody wants to take the time! But it's fool proof! Even times in shops you would tell the customer it is usually this part but it's a gamble on you if we don't do a leak down test first, and 9 out of ten say no problem just change it and if it don't work well teat it????? All you can do is suggest the right way, if they think they know best or have a horseshoe up their bum, great more money for me lo!
thanks, this channel started as me setting strait some shit talk, and I found it fun, yet this video, I almost deleted, and so far its still my biggest hit, lmao! I been hanging in here on a thread, but i do have a shit ton and a half of videos on the editing block ready to dump on youtube steady for a while, finally found the time, well, here goes nothing... thanks again!
I had a new Ford Ranchero with a 351 that stopped running while driving down the road. I could smell the gas, so I knew it wasn't fuel and surmised it had to be electrical. Pulled the distributor cap and didn't see anything wrong at first. But after checking it for the third time, noticed the little rubbing block on the points was missing. I'd never seen that happen before or since to any vehicle.
This seems to be a huge problem with the rubbing blocks on new points, better off new old stock... I love them things! I was gonna drop a Cleveland in my 80 ranger b4 I found my scout!
Nice. Me too, a failed coil was hard to diagnose as they are fairly reliable and it was intermittently going bad until it took a crap on my PCM powered nautique middle of the lake.
some people have luck and guess right 9 out of 10, like that one guy you know that some how wins every damn raftle or contest lmao, and some of us what can fuck up will fuck up so im quick to start right off with a vacume gauge then a full mechanical leakdown to pinpoint any issues found, then and or a full eletrical leak down... most the time.... id say even if you hit 9 out of ten, twenty miniuts of fiddeling on all 10 is less time and money wasted than the one free repair that was unnessary based on false diagnosis!
Good video. Very informative. You make it short , sweet and simple. Now I fully understand the coil and distributor functions and how to properly test the ignition system.
PROBABLY YOUR IGNITION STARTER SWITCH IN THE STEERING COLUMN,CHECK YOUR IGNITION FUSE AND ECM FUSE SEE IF THEY LIGHT UP WITH A TESTING LIGHT WHEN YOU TURN KEY ON.IF THEY DONT THAT'S YOUR PROBLEM.
Sorry, my eyes glazed over when I noticed there were no points. Great information for those with newer rigs (1975 and up). Yup, I have a hard time wrapping my mind around electronic ignition. Eventually I'll have to bite the bullet and buy something from the mid 70's and maybe even the 80's! "If you're gonna be poor, don't also be helpless".
I am all about points, nothing wrong with points, I prefer points, this is just what my broke behind had on the shelf when my distributor wore out. the easy answer, electronic ignition is exactly like points, except, the points do not contact. they arc at a very low volt/amp, not enough to get the coil to trigger the spark, so it has a little capacitor to step up the voltage. nothing has changed in cars in 50 years (other than vvt) its all the same except us mechanics have been replaced with computers, and 9$ an hour parts changers lol and a capacitor is triggered
Would you believe someone just stepped on it, that’s what I get for doing favors lol. What pissed me off, is radio shack claimed bankruptcy. That means they don’t have to pay their debts, yet they tried to come after me for the remaining balance on my RadioShack card! Wait a minute, RadioShack falters on debt but says I owe them still. Ha! Cold day in hell! I do miss being able to say put it on my account, still till they close, no card needed, just put it on my account....
thxs that was explained better then anyone I have heard or watched bden fighting with dumb amc jeep wiring system and I think this will help more then people showing me on that system
would of loved to see him install the part & see it start wish i would of seen this video before i sold my step van brought it to an asshole mechanic who didn't know shit but this gentleman really knows his stuff 2 thumbs up
Bro thanks for the info, i very sure i cant not make my friend car wotk i replaced coil and have same problem i remove my control module and buy new one and bang bro you are so smart thanks again
Hey Eric I must say you seem quite knowledgeable, so maybe you can help me ? After watching this video there’s a lot that comes into play in similar fashion with my 69 cougar I have crank no start no spark at the coil from either the coil or the plug wire a concern to me not knowing is I show 19 volts when the key is on at the positive of the coil not sure if that’s a good number I’ve tried switching up my points and condenser to another use set on another 69 cougar I have that has also sat for a while so I’m not sure if overtime these have gone bad too but still no spark I’ve checked wires and clean ground areas on the back of the starter solenoid and replaced the voltage regulator module I’m about to clean the ground to the engine block as I heard this could be a situation to no start even though it cranks over I have just bought a Pertonix to replace the points but sure if I should install it with that 19 V coming in at the coil when the ignition is on I don’t wanna damage anything on the pertronix what should the voltage be coming in on the positive terminal of the coil when the key is on and showing at the solenoid the same voltage? Please help thanks
so, right off the bat, think your meter is bad, check the battery... 19volts... that or you have dual batteries wired in series on accident... you should never get more than like 10 volts it has a big resistor to drop it down.. when you are cranking it over, it bypasses the resistor and gives it a straight 14 ish volts... for cranking, when not cranking it saves the points to run at 9.6 volts... the sure test, one end of volt meter to ground, and trace the circuit top down... probe the wire b4 and aft every switch or connector, and if the voltage is lower after any connection than b4 it, its a bad connection... just jump the coil straight to the battery and see if you got spark then, see if the coil powers up now, this will save you all day tracing wires if its just a bad coil. should be able to short the neg lead of coil to ground real fast zap, make it spark.... points can be bad new now days and its a 50 50 shot!!! so discharging the coil manually will be the easy test... Get that mean cougar back on the road!!!
This starter motor sounds like my Dad's old 1978 Australian Ford Fairlane. Interesting. I'm in New Zealand. Unfortunately, we don't have it anymore, and he's dead.
What I have is a 351w, marinized! Have new pertronics flamethrower 2 0.6 ohm coil 45,000 volts, as recommended. on 200 ohm setting the positive to negative test settles down to 1.1...., replacing old flamethrower 2 0.6 ohm which won't settle down in that test, can fluctuate around 2.4 for a while and then around 1.5 for a while and sit still at 1.3 for a while and without breaking contact you could see any of this going on. The new flamethrower reads 10.0 or 9.96 on the 20K test to the main wire, while the old one reads 8.77. I've got gas and apparently no spark, but I also have a brand new pertronics coil and distributor. I'm losing it!
@@TEN-TIMES-HARDER no... But I do have 12 volts at the coil and replaced ends on both wires to the positive on the coil. The engine originally failed while running at 35 mile an hour. It cranks nicely I checked spark from the coil wire, it looks yellowish instead of blue and it's a brand new coil as I was saying. I'd like to think there's something wrong with my brand new parts. I don't know what readings I'm supposed to have on a new pertronics coil. Best I got was 10 where you were looking for 10.5 on your application.
ten is fine,, is the distributor a tooth off? i assume its not a reverse spinning marine engine made for dual engine crafts.... you will need to chase each wire, check the connections, clean them, check resistance across them with the battery disconnected for resistance... clean the ground, test the battery and the altenators output, and if its all good, and you dont have a faulty ignition switch, you likely got a turd that slipped past quality control... so on the side marine engines are higher compression and need to run on at least 100 octane....
I screwed up bro on my 65 stand, inline 6, I didn't tie down the battery so while driving, the positive to the battery touched the front support frame and melted the wire to the battery, not the car won't start. I fried something for sure, first I assumed it was the starter relay, I got a new one, not it. I tried a new battery still nothing, I don't have spark so I'm assuming I don't have power to the distributor, which is a HEI. What could it be? is there a way to bypass the resister wire and go direct to the distributor? did I fry the distributor or another wire? Dam!!! Rockie move man
yes so if power went to the body it had to get back to the neg terminal. this means the shortest easiest path. so if it went through the body it had to go through the ground strap that goes from engine to the firewall, through the engine, then to the negative cable to the battery.... so if the ground strap to the cab or body were corroded or missing it may have just went home backwards through the ignition switch, or the coil / distributor, frys computers even with a good ground half the time... So yes you can just hook it up straight to battery to test it and jump the starter, this will not be a problem, points last longer at 9 volts and its all they need, they still like 12 to start, thats why the resistor. if you dont have points you need to remove the resistor btw... so yeah check the ignition switch and jump it....
'85 Ford F150, 4.9L I6, 4wd. Intermittent missfires initially blamed on water in fuel. Then all stop and no spark. '85 has 2 electronic control modules...on screwed to distributor under the body and the 2nd on the passenger sided wheel well next to the starter relay. The first one can be tested and changed. Tthe 2nd is apparently vacuum switched. Cannot find testing instructions or replacement part. None available have vacuum line as part of plug-in. Your thoughts?
I'm pretty sure I got the same issue I've replaced the balast resistor on the firewall ,pickup coil inside the distributer, the pligs,wires,starter,alternator, fuelpump,and coil, but still nothing I've tried 3 different ignition coils still nothing I don't have a multimeter just a tac meter for small electronics for like speaker wire or fuses . When I did test the current coil on the terminals it read 100% green keep in mind its not the proper tool. But when testing the wire hole where the plug wire snaps into it drops to about 45-50% power I wouldn't think it could be the icm under my steering colum but I'm just assuming that just because it turns on off and turns the starter over without a problem it's on a 87 dodge d150 360 v8 5.9l dual pickup coil distributer
here schematron.org/1987-dodge-d150-wiring-diagram.html you dont have a balast resistor thats for points, the extra wire is a low oil pressure kill switch. so if the oil light is on the distributor wont fire.....
No disrespect but he sounds like Casey jones from the first ninja turtles movie 😎🤘. I'm helping my dad work on his 1978 chevy truck 350 with hei distributor. It ran the other day in town then shut off . my dad had to restart the truck drove it home . rotates now but nonstart or spark. Replaced the cap rotor and coil and the 4 prong icm. Still no start? Its either the pickup coil or the starting switch mount on top of the steering column since a non tilt column ?
Hey I’m having a no start issue on my 1978 Porsche 924, I’ve replaced the faulty ignition coil (resistance measurements were off spec) however still no start, but I’ve noticed there’s 2 ballast resistors before the coil wich take the voltage down, I’ve measured them and the 1st one takes the voltage down from 12v to 8v and the 2nd one takes it down from that 8v to like 5.4V. This seems strange to me, as people say the coil needs 12v, do you think I should remove those resistors?
ok, on a points distributor, it runs off of 9.6 volts. you know how on the starter relay their is the bypass wire only on cars w/ points distributors. well that will bypass the resistor and give full 12.6 volts to the coil, only when cranking. once its running it goes through resistor again. you must have a bad ballast resistor circuit , sounds like someone messed with it. also, you should be reading 9.6 and 12.6 to 14.6... not 8 and 12. so also check your meter is calibrated, your battery is good, and your alt is working, and you dont have any corrosion creating a false load on the switch or relay or any of the connectors. I will put a video out on electrical leakdown test, but your coil should be getting 9.6 volts except when you are trying to start it. this is because if it ran at full voltage all the time, it would burn up the points, most of the wear on your points happens when your cranking then runs at a safe 9volts... it actually winds up making about the same spark because its still the same amperage, remember, its high amps that can kill you not volts... if you check my webpage in the IH section, its going to be universal information on most engines and wires, other than the colors and firing order... www.ironhammer.info/ih.html , and the more I think about it, Im not sure a 78 would still have points, so even weirder... their should be no resistor at all unless you have a points distributor. its possible it has some fancy dual points distributor. points are better, they just require regular maintenance..
Thanks for video. I have 83 Jeep cj7 running 2 weeks ago. Now no spark from coil wire. Removed dist cap and found the center pin on cap had broken off and was imside dist. I have Mallory dist and ignition coil. Red wire inside dist has a break in the insulation. Went to oem dist and Accel coil also replaced ballast resistor still no spark from coil wire. I'm stumped. Aloha from Hawaii!!! Any advice??
Ahh, well, I dont think you would have points on an 83. if so, a points distributor has a resistor to run at 9.6 volts so you dont burn the points up. It also has a bypass wire, so when you are cranking it bypasses the resistor to run a full 14.6 volts until it until it starts, but you should have a magnetic pickup. and should not have the resistor or bypass. I go over that in my video ua-cam.com/video/0P_qU7I2n4Q/v-deo.html... you either have a prestolite style or a brain box style where the circuit board is mounted outside the distributor and they go bad...
@@TEN-TIMES-HARDER well I had Mallory coil and Mallory dist. And also note there is no icm below the washer box on the driver fender. Not sure what that's about. Replaced with a cell coil and own dist dist cap and rotor. Getting 12 volts to coil and it's pulsing properly but still not getting fire from top of coil. Bypassed the resistor and I still can't figure this out.
well, capacitor discharge ignition has a brain box or it is mounted under the plate. thats why i show vid on installing a pertronix igniter in a prestolite distributor. or non-points mallory have the same thing like in that vid. here is how it works. under the rotor. their is a lobed wheel. and a magnetic pickup. (like a crank position sensor for new cars) when the lobe gets close to the pickup, the magnetic field is disrupted. This triggers the brain then, amplifies it with transistors/capacitors and sends signal to the coil to dump the spark, then its sent through what ever wire the rotor is pointing at under the cap. so if the circuit board is bad or the pickup is bad, it dont know to send a spark, just like if your points where not contacting....
your coils are burning out? i would check your wires. is the coil still getting power when its off. see the system is simple. a key sends power to coil in on position through a resistor wire or a ballast resistor, giving the coil 9 volts. when starting a second wire with out a resistor gives the coil full 12 volts. or you just get straight 12 when its on if its hei. so coil has power. points or pickup tells coil to dump coil dumps charge to what ever plug the rotor is pointing at. so as you say, what could be burning up a coil. bad ground? bad plug wires? is if running on all 8? spark returning with out jumping the gap like gap closed or carboned.....
Never spark test near the battery. Typical lead acid batteries occasionally vent Hydrogen gas. I saw a "Know it all" almost get his hand blown off by checking spark on the negative battery terminal with a screw driver. Other than that this is a good informative video.
I thought I wrote not to, I only did it there for filming reasons. I honestly never heard of anybody actually having this happen or a car running at the pump blow up the town, other than from my h s shop teacher talking about the 50's, but it could under once in a blue moon conditions, no wind, hot, dry, just the right fuel air mixture lol So Yes your right, this should be avoided, or know your risks. I did have a fire extinguisher near and was safe, unless I panicked or hesitated, I was fine, worst case i would have lost wires and lines.... yet still why risk a 200$ battery! I guess what I am saying , is i always look at every situation with caution, not just red flags... So I am just adding that the more aware of your surroundings, the safer you are and less grey area. So to take it a step further, realistically we need to be always aware of every accelerant or flammable matter in every situation, of every potential weapon in the room and where every bodies hands are in relation to them... the more you know the closer to the line, the more from life! I love to learn! Just never hesitate and everything else is out of your control... thanks for pointing that out...
yeah dodge used the prestolite too, most parts are over the counter still they aint as obscure as people think.... They where just oveer built and you paid a lot more for it...
is this the same concept for 77 chevy monte carlo? changed spark plugs, wires, distributor cap and rotar and coil. car does same thing your truck is doing in this clip
YES SIR, IN FACT THE ONLY DIFFERENCE IS WE IH GUYS TIME OFF NUMBER 8 AND NOT 1! REVERSED GM FIRING ORDER... OUR CAMS SPIN BACKWARDS BECAUSE ITS GEAR TO GEAR DRIVEN, NO CHAIN.
I still can’t figure out what’s going on with my car. Mind giving me some help? I’m not good with the electrical stuff. 1986 Nissan 300ZX 2+2 - V6 - 3.0L 2960cc 181ci GAS TBI vin H type VG30 - 2 valve SOHC
so if you would like a simpler test, put a spark test (or screwdriver) on the end of the wire directly off the coil itself. you can take a jumper wire from ground, and touch it momentarily to the neg side of coil, it will spark as long as you have power to the pos of coil!!! if not, jump power right to pos side of coil and try again, if that works your coil is not getting power or you have bad ignition switch
I'm thinking you tested a 1.5 ohm coil. So if I have a pertronixs 0.6 ohm coil, it should read 0.6? On the other test I only got 8.5 through the center coil wire.
the 4 banger here has a 3 ohm coil, the 8 has 1.6ohm across terminals, the main windings, the from post to main plug wire, should read 10.5, 8.5 is low like the coil windings coating failed, and its skipping or shorting past some of the coil...
So after following your instructions which seem to be the easiest to understand on UA-cam I'm getting a reading of 8.25 which is a little lower than yours so would that mean my coil is bad? Thanks for any advice
I will find it in the comments later, I answer this question a lot, have to run to work now, the crank position sensor is not inside a distributor its on the block by the cam shaft end, same process as in the video , just spread out
I have a 90 tbi in caprice i have fuel i only have spark coming from coil but no spark from distributor spark plug wire to the plug i changed the icm with a few new ones i still cant get spark to come out of spark plugs such an headache
just an OTC spark tester, I got mine from the tool store , here is there online link www.toolmarket.com/product-spark-tester-electronic-ignition_30157.aspx
just so you know in case you havent figured it out yet. ford doesnt make a 400 ci engine galaxies most of the time have 390 engines. 400 is a gm engine.
I was a honda suzukie dealer mechanic for a short while lol, i actually have some bike videos, a lot of videos, all on the editing bench lol..... its hard to find the time to put them up when im trying to get caught up with my customers lol
I'm less than a beginner, so my question is the values of impedance and voltage you talk about are standar values for lets say petrol engines, or do they vary accordingly with something for instance, brand or every engine is buit to run with a certain kind of impedance or voltage and those values are provided by the manufacturer.If myquestion turns to be a bit confusing, i mean how do you know the right reference values when it comes to electricity?
jose pontes , some heavy equipment might be 24 volt, and some old cars, pre late 60,s, where 6 volt ( and most have been converted to 12 by now) But otherwise even semi-trucks and motorcycles are all 12 volt. (Or 14.6 running). The resistance on the coil will be the same for all v8 petrol, propane, alcohol....or close to it, oh, some old motorcycles and mopeds are 6volt as well... but we're talking 70,s When doing leakdown test you will need to know the resistance of what ever part your testing, manufacturer specific according to manual, but if you buy the Haynes manual for obd2 codes they have general numbers that are good most the time... also voltage divided by amperage equals resistance, if you know the amps... I will make a video on leakdown test soon, I have so many videos I haven't had time to upload yet! Just been busy at work....
I have a 1963 buick 198 v-6. Car sat 20yrs. Replaced everything electrical- power at both sides of ign. Coil- no spark at plug?? Power good between points contacts- how come no spark on plug?
k, points has 2 hot wires. When the key is in the run position , a wire from the ignition switch with a ballast resistor powers the coil at 9.6 volts. K, so when the key is in the start position it bypasses the resistor and gives it a full 12.6 volts to help it start. so the ignition switch itself is very common failure, it can also be a bad resistor, or even the starter solenoid. You will notice it has 2 wires. one is from the key to activate the starter, one is for the resistor bypass to start voltage.... so their are your check points, I have a wire diagram on www.bedhed.xyz/ih so with key on, you should have 9.6 volts to the coil!!! if not u have bad resistor, wire, or switch! with the key in start position, you should have 12+. if you have both, check your points or condenser, they are like 2 out of 3 bad from the factory now days!!! so unless you have major problem like the distributor aint turning.........
@@TEN-TIMES-HARDER ok, I Just got out to check everything I read last night. First thing I found is the ground from the engine to the frame is broken! Does it need to be grounded to start? Next I’ll check the ignition switch. When the key is on I have power on both sides of the coil? Is that normal? Everything electrical is new, including the starter and alternator. Where is the resistor? Thx a million for your help
@@TEN-TIMES-HARDER there’s no wiring harness in this car. It has very few wires. Wires from ignition switch, starter relay/solenoid- voltage regulator, that’s about it. I can see all the wires and they look ok, just the ground strap was broken. The next problem is no or low compression? I pulled plugs and squirted in each cylinder. Squirted the tops of push rods and valve springs. I have a weird rocker system?? It has a rod with springs bolted down over the top of the valve springs so there’s no adjusting the rockers? U seen this type before?? Thx man!!
nah, lot of myths, they have merit, like the whole thing of batteries draining on the floor, thats from when they came in wood cases! Half of it is insurance company bs..... Did you know that a lap belt is better than a single shoulder strap, unless you have a x or two of them, its instant spinal damage and whiplash.... the odds of half this shit like your car running while pumping gas exploding, would mean every wire short on every car would blow up the gasstations or your battery.....
Hey any advice? I’ve replaced the ignition control module, ignition coil, distributor, and plugs with still no spark, I have a 96 f150 with a 351 Windsor and I’m running out of things to replace and money! Any advice would be appreciated!
I mean if we are looking at rare things is the engine grounded? But I would do a leakdown test. Sometimes even the pins in the bulk connectors get pushed out... but you really need to prove every connection and eliminate the basics, is everything getting power, and shirts or false loads, is the ground good, is the ignition switch good, if you jump power to the coil from. Battery... heck in computercontrolled cars a bad battery can cause issues but yours sounds like a short or a bad part, it’s pretty simple, key goes on and coil/distributor get power, Then key goes to start and everything but the coil/distributor loose power while the starter engages. When camshaft turns it turns the distributor shaft by the gear. Then the rotor points at a cylinder and the magnetic pickup tells the coil to dump the spark at said cylinder, with some interference from the control module controlling the spark. And that’s all there is to it. So if the distributor rotor is turning, and your rotor is good, and assuming your new parts are good. You must have a short
ERIK THE WRENCH Turns out I bought a faulty set of ignition components, installed the original with the new distributor and crankshaft sensor and now she purrs first key turn, thanks for your help!
Ok, I am curious now. I just bought a boat with a Mercruiser 3.7 that has points. It appears that I can upgrade the point system to a magnetic pick up like in your video. Is the magnet pick up all that is needed with a direct connection to the coil or is there a control module somewhere in-between.
That's the cool thing about pertronix the control board is built in to the backing plate for the rotor! So all you need to do is remove galaxy resistor that is in line to the coils power. See that's what that r terminal is on your starter. The points run on 9v, so their is a 3v resistor in series b4 the coil... so the when starting, the resistor gets bypassed and the coil gets full voltage to help start.
New Control Module and have found and installed new MAP Sensor and problem persists...with a twist...mis seems to occur only when driving down hill...power good up hill and on level roads. Everything i've read indicates engine cannot be re-timed because the electronics get in the way. So, if i set #1 at TDC with rotor pointing there, then hand crank engine to 10deg BTDC and lock down the distributor, is it correct to presume that the electronics will do the rest? One more consideration...i live at 7200' altitude and seldom drive below 5,000' altitude.
If it is an IH power plant, it gets timed off number 8cyl! the camshaft turns the opposite direction due to the cam is a direct gear drive, no chain.... Also at higher altitude you have to rejet your carb, but your computer should adjust on injection...should... it is possible the injector is dirty or bad fuel pressure. so with out the backpressure from going up or level, it would show the lean symptoms more.... can even be something in the tank floating around.... filter... pump... the pressure regulator... so I would test for pressure... Also Map sensor must be clean clean clean and with map cleaner, if you got anything on it it will fail, also get the voltage specs and see if the map sensor has a broken wire running to it.... If you do not set the timing to factory usually you need a chip or a computer flash.... Not sure what your working with... how steep a degrade? the wrong gear even lol Are you getting any codes? even spark plug wires routed wrong can send false signals and trick the module! you dont need to adj mechanical timing for alt... You may need hotter or colder spark plugs if you have modified the timing, a colder plug will transfer heat faster out the chamber... so is it a random multiple missfire or a particular cyl? random is usually from lean or bad timing.... can also have worn springs on the advance weights in dist or a sloppy shaft....
even if you disconnected the egr or messed with the pcv.... Egr actually was a way to trick emission test. see they lowered compression to pass, and gave it an egr, so that on idle its a lower compression... The the recirculated exhaust dont compress like the air, so it raises your compression under a load! might be bad... with out the pcv it will run rich if you dont compensate...
So do you get lower voltage at the coil if your pickup coil is bad or damaged? What if the gap between the pickup coil and the reluctor isn't adequate? Could that also cause a drop in voltage at the coil?
The coil is charged like a capacitor right, straight 12-14volts. goes to the coil. unless its points then it gets 9.6v! As soon as it can ground out, and complete the circuit, it does. It does this through the cap and rotor and goes to what ever plug wire its pointing at.

Plus the calm and methodical way you presented yourself.
This is the smartest mechanical genius I ever listened to
I want to sincerely thank you for this video. I have been catching hell trying to get my Charger to start after letting it sit over a year. I had it in my mind that it was the fuel pump. Then I was thinking I didn't install it right. Could not get it to start. Was thinking of replacing the distributor, ignition module.. etc.. just guessing. Your video DID THE TRICK! I ohmed out the coil just like you showed and compared it to two other coils (one brand new) and that was the issue. That 440 is running like a champ now. I cannot thank you enough.
RIcky Rick my pleasure!
MY 77 F350 always starts up. today no crank and nothing. was about to call a mechanic to come check it out. saw your vid. did the steps and everything was working until i switched the ignition module. started up instantly.
thank you sir. Thanks to you, i learned something new today.

Thanks for the effort you put into this video! Took my 76 Ford dump truck to the mechanic but every one of them in town is to lazy to diagnose like this. They just say to run it until it won't then bring it in. If you want it done right sometimes you have to do it your self.
Got the one on pertronix and vacuum gauge power tuning is part two. A vacuume gauge will.tell.you most mechanical issues. The next one in putting out is on a leak down test. A leak down test.is the only way to pinpoint / prove any mechanical issue before proceeding and not just guessing but nobody wants to take the time! But it's fool proof! Even times in shops you would tell the customer it is usually this part but it's a gamble on you if we don't do a leak down test first, and 9 out of ten say no problem just change it and if it don't work well teat it????? All you can do is suggest the right way, if they think they know best or have a horseshoe up their bum, great more money for me lo!

Nice work man ....... before I pull my carby off I'll test my coil . You have helped me today , thank you Erik the Wrench
how did it go and what was it?
I had a new Ford Ranchero with a 351 that stopped running while driving down the road. I could smell the gas, so I knew it wasn't fuel and surmised it had to be electrical. Pulled the distributor cap and didn't see anything wrong at first. But after checking it for the third time, noticed the little rubbing block on the points was missing. I'd never seen that happen before or since to any vehicle.
This seems to be a huge problem with the rubbing blocks on new points, better off new old stock... I love them things! I was gonna drop a Cleveland in my 80 ranger b4 I found my scout!

Good video. Very informative. You make it short , sweet and simple. Now I fully understand the coil and distributor functions and how to properly test the ignition system.
PROBABLY YOUR IGNITION STARTER SWITCH IN THE STEERING COLUMN,CHECK YOUR IGNITION FUSE AND ECM FUSE SEE IF THEY LIGHT UP WITH A TESTING LIGHT WHEN YOU TURN KEY ON.IF THEY DONT THAT'S YOUR PROBLEM.
Sorry, my eyes glazed over when I noticed there were no points. Great information for those with newer rigs (1975 and up). Yup, I have a hard time wrapping my mind around electronic ignition. Eventually I'll have to bite the bullet and buy something from the mid 70's and maybe even the 80's! "If you're gonna be poor, don't also be helpless".
I am all about points, nothing wrong with points, I prefer points,
this is just what my broke behind had on the shelf when my distributor wore out.
the easy answer,
electronic ignition is exactly like points, except, the points do not contact. they arc at a very low volt/amp, not enough to get the coil to trigger the spark,
so it has a little capacitor to step up the voltage.
nothing has changed in cars in 50 years (other than vvt)
its all the same except us mechanics have been replaced with computers, and 9$ an hour parts changers lol
and a capacitor is triggered

Hey Eric I must say you seem quite knowledgeable, so maybe you can help me ? After watching this video there’s a lot that comes into play in similar fashion with my 69 cougar I have crank no start no spark at the coil from either the coil or the plug wire a concern to me not knowing is I show 19 volts when the key is on at the positive of the coil not sure if that’s a good number I’ve tried switching up my points and condenser to another use set on another 69 cougar I have that has also sat for a while so I’m not sure if overtime these have gone bad too but still no spark I’ve checked wires and clean ground areas on the back of the starter solenoid and replaced the voltage regulator module I’m about to clean the ground to the engine block as I heard this could be a situation to no start even though it cranks over I have just bought a Pertonix to replace the points but sure if I should install it with that 19 V coming in at the coil when the ignition is on I don’t wanna damage anything on the pertronix what should the voltage be coming in on the positive terminal of the coil when the key is on and showing at the solenoid the same voltage? Please help thanks
so, right off the bat, think your meter is bad, check the battery... 19volts... that or you have dual batteries wired in series on accident... you should never get more than like 10 volts it has a big resistor to drop it down.. when you are cranking it over, it bypasses the resistor and gives it a straight 14 ish volts... for cranking, when not cranking it saves the points to run at 9.6 volts... the sure test, one end of volt meter to ground, and trace the circuit top down... probe the wire b4 and aft every switch or connector, and if the voltage is lower after any connection than b4 it, its a bad connection... just jump the coil straight to the battery and see if you got spark then, see if the coil powers up now, this will save you all day tracing wires if its just a bad coil. should be able to short the neg lead of coil to ground real fast zap, make it spark.... points can be bad new now days and its a 50 50 shot!!! so discharging the coil manually will be the easy test...
Get that mean cougar back on the road!!!

What I have is a 351w, marinized! Have new pertronics flamethrower 2 0.6 ohm coil 45,000 volts, as recommended. on 200 ohm setting the positive to negative test settles down to 1.1...., replacing old flamethrower 2 0.6 ohm which won't settle down in that test, can fluctuate around 2.4 for a while and then around 1.5 for a while and sit still at 1.3 for a while and without breaking contact you could see any of this going on. The new flamethrower reads 10.0 or 9.96 on the 20K test to the main wire, while the old one reads 8.77. I've got gas and apparently no spark, but I also have a brand new pertronics coil and distributor. I'm losing it!

@@skidancin and have you tried jumping the coil right to the battery
@@TEN-TIMES-HARDER no... But I do have 12 volts at the coil and replaced ends on both wires to the positive on the coil. The engine originally failed while running at 35 mile an hour. It cranks nicely I checked spark from the coil wire, it looks yellowish instead of blue and it's a brand new coil as I was saying. I'd like to think there's something wrong with my brand new parts. I don't know what readings I'm supposed to have on a new pertronics coil. Best I got was 10 where you were looking for 10.5 on your application.
ten is fine,, is the distributor a tooth off? i assume its not a reverse spinning marine engine made for dual engine crafts....
you will need to chase each wire, check the connections, clean them, check resistance across them with the battery disconnected for resistance... clean the ground, test the battery and the altenators output,
and if its all good, and you dont have a faulty ignition switch, you likely got a turd that slipped past quality control...
so on the side marine engines are higher compression and need to run on at least 100 octane....
Did it fix the problem and generate a spark...
Perfect position for it to be stuck.... of course
got me dying

Perfect tutorial. Having the exact same problem
Great video lots of detail thank you
I hack it lmao
I screwed up bro on my 65 stand, inline 6, I didn't tie down the battery so while driving, the positive to the battery touched the front support frame and melted the wire to the battery, not the car won't start. I fried something for sure, first I assumed it was the starter relay, I got a new one, not it. I tried a new battery still nothing, I don't have spark so I'm assuming I don't have power to the distributor, which is a HEI. What could it be? is there a way to bypass the resister wire and go direct to the distributor? did I fry the distributor or another wire? Dam!!! Rockie move man
yes so if power went to the body it had to get back to the neg terminal. this means the shortest easiest path. so if it went through the body it had to go through the ground strap that goes from engine to the firewall, through the engine, then to the negative cable to the battery.... so if the ground strap to the cab or body were corroded or missing it may have just went home backwards through the ignition switch, or the coil / distributor, frys computers even with a good ground half the time... So yes you can just hook it up straight to battery to test it and jump the starter, this will not be a problem, points last longer at 9 volts and its all they need, they still like 12 to start, thats why the resistor. if you dont have points you need to remove the resistor btw... so yeah check the ignition switch and jump it....

I got a 1990 Dodge with a V6 cranks no spark
'85 Ford F150, 4.9L I6, 4wd. Intermittent missfires initially blamed on water in fuel. Then all stop and no spark. '85 has 2 electronic control modules...on screwed to distributor under the body and the 2nd on the passenger sided wheel well next to the starter relay. The first one can be tested and changed. Tthe 2nd is apparently vacuum switched. Cannot find testing instructions or replacement part. None available have vacuum line as part of plug-in. Your thoughts?
The second module is a vacuum sensor to control timing advance based on manifold pressure...
How you know what to set the meter at ? And what numbers you were suppose to get in order to tell if it was right or not?
Capt. Mike Allen I have the same question as well
2:13
I'm pretty sure I got the same issue I've replaced the balast resistor on the firewall ,pickup coil inside the distributer, the pligs,wires,starter,alternator, fuelpump,and coil, but still nothing I've tried 3 different ignition coils still nothing I don't have a multimeter just a tac meter for small electronics for like speaker wire or fuses . When I did test the current coil on the terminals it read 100% green keep in mind its not the proper tool. But when testing the wire hole where the plug wire snaps into it drops to about 45-50% power I wouldn't think it could be the icm under my steering colum but I'm just assuming that just because it turns on off and turns the starter over without a problem it's on a 87 dodge d150 360 v8 5.9l dual pickup coil distributer
here schematron.org/1987-dodge-d150-wiring-diagram.html you dont have a balast resistor thats for points, the extra wire is a low oil pressure kill switch. so if the oil light is on the distributor wont fire.....
No disrespect but he sounds like Casey jones from the first ninja turtles movie 😎🤘. I'm helping my dad work on his 1978 chevy truck 350 with hei distributor. It ran the other day in town then shut off . my dad had to restart the truck drove it home . rotates now but nonstart or spark. Replaced the cap rotor and coil and the 4 prong icm. Still no start? Its either the pickup coil or the starting switch mount on top of the steering column since a non tilt column ?

this is great information thank you man.
Hey I’m having a no start issue on my 1978 Porsche 924, I’ve replaced the faulty ignition coil (resistance measurements were off spec) however still no start, but I’ve noticed there’s 2 ballast resistors before the coil wich take the voltage down, I’ve measured them and the 1st one takes the voltage down from 12v to 8v and the 2nd one takes it down from that 8v to like 5.4V. This seems strange to me, as people say the coil needs 12v, do you think I should remove those resistors?
ok, on a points distributor, it runs off of 9.6 volts. you know how on the starter relay their is the bypass wire only on cars w/ points distributors.
well that will bypass the resistor and give full 12.6 volts to the coil, only when cranking. once its running it goes through resistor again. you must have a bad ballast resistor circuit , sounds like someone messed with it. also, you should be reading 9.6 and 12.6 to 14.6... not 8 and 12. so also check your meter is calibrated, your battery is good, and your alt is working, and you dont have any corrosion creating a false load on the switch or relay or any of the connectors. I will put a video out on electrical leakdown test, but your coil should be getting 9.6 volts except when you are trying to start it.
this is because if it ran at full voltage all the time, it would burn up the points, most of the wear on your points happens when your cranking then runs at a safe 9volts... it actually winds up making about the same spark because its still the same amperage, remember, its high amps that can kill you not volts... if you check my webpage in the IH section, its going to be universal information on most engines and wires, other than the colors and firing order... www.ironhammer.info/ih.html , and the more I think about it, Im not sure a 78 would still have points, so even weirder... their should be no resistor at all unless you have a points distributor. its possible it has some fancy dual points distributor. points are better, they just require regular maintenance..
Thanks for video. I have 83 Jeep cj7 running 2 weeks ago. Now no spark from coil wire. Removed dist cap and found the center pin on cap had broken off and was imside dist. I have Mallory dist and ignition coil. Red wire inside dist has a break in the insulation. Went to oem dist and Accel coil also replaced ballast resistor still no spark from coil wire. I'm stumped. Aloha from Hawaii!!! Any advice??
Ahh, well, I dont think you would have points on an 83. if so, a points distributor has a resistor to run at 9.6 volts so you dont burn the points up. It also has a bypass wire, so when you are cranking it bypasses the resistor to run a full 14.6 volts until it until it starts, but you should have a magnetic pickup. and should not have the resistor or bypass. I go over that in my video ua-cam.com/video/0P_qU7I2n4Q/v-deo.html... you either have a prestolite style or a brain box style where the circuit board is mounted outside the distributor and they go bad...
@@TEN-TIMES-HARDER well I had Mallory coil and Mallory dist. And also note there is no icm below the washer box on the driver fender. Not sure what that's about. Replaced with a cell coil and own dist dist cap and rotor. Getting 12 volts to coil and it's pulsing properly but still not getting fire from top of coil. Bypassed the resistor and I still can't figure this out.
well, capacitor discharge ignition has a brain box or it is mounted under the plate. thats why i show vid on installing a pertronix igniter in a prestolite distributor. or non-points mallory have the same thing like in that vid.
here is how it works.
under the rotor. their is a lobed wheel. and a magnetic pickup. (like a crank position sensor for new cars) when the lobe gets close to the pickup, the magnetic field is disrupted.
This triggers the brain then, amplifies it with transistors/capacitors and sends signal to the coil to dump the spark, then its sent through what ever wire the rotor is pointing at under the cap.
so if the circuit board is bad or the pickup is bad, it dont know to send a spark, just like if your points where not contacting....
My same situation. BUT what is causing my coil burnouts - that what I need to find.
your coils are burning out? i would check your wires. is the coil still getting power when its off. see the system is simple.
a key sends power to coil in on position through a resistor wire or a ballast resistor, giving the coil 9 volts.
when starting a second wire with out a resistor gives the coil full 12 volts.
or you just get straight 12 when its on if its hei.
so coil has power.
points or pickup tells coil to dump
coil dumps charge to what ever plug the rotor is pointing at.
so as you say, what could be burning up a coil.
bad ground?
bad plug wires?
is if running on all 8? spark returning with out jumping the gap like gap closed or carboned.....
Never spark test near the battery. Typical lead acid batteries occasionally vent Hydrogen gas. I saw a "Know it all" almost get his hand blown off by checking spark on the negative battery terminal with a screw driver. Other than that this is a good informative video.
I thought I wrote not to, I only did it there for filming reasons. I honestly never heard of anybody actually having this happen or a car running at the pump blow up the town, other than from my h s shop teacher talking about the 50's, but it could under once in a blue moon conditions, no wind, hot, dry, just the right fuel air mixture lol So Yes your right, this should be avoided, or know your risks. I did have a fire extinguisher near and was safe, unless I panicked or hesitated, I was fine, worst case i would have lost wires and lines.... yet still why risk a 200$ battery!
I guess what I am saying , is i always look at every situation with caution, not just red flags... So I am just adding that the more aware of your surroundings, the safer you are and less grey area. So to take it a step further, realistically we need to be always aware of every accelerant or flammable matter in every situation, of every potential weapon in the room and where every bodies hands are in relation to them... the more you know the closer to the line, the more from life! I love to learn! Just never hesitate and everything else is out of your control... thanks for pointing that out...
I didn't believe it either until I saw it for my self. I have a picture of the battery somewhere.
I replaced my uncle fuel pump, coil, filter, ecu, and the man relay! Still no crank! He has 1985 Dodge ram d150 318

thank you, about to do a lot more
very detailed information good video 👍👍
Should all coils have the same readings? for instance I have a Pertronix coil and I'm getting no spark
so if you would like a simpler test, put a spark test (or screwdriver) on the end of the wire directly off the coil itself. you can take a jumper wire from ground, and touch it momentarily to the neg side of coil, it will spark as long as you have power to the pos of coil!!!
if not, jump power right to pos side of coil and try again, if that works your coil is not getting power or you have bad ignition switch
Friggin awesome video dude!
Cheeers from Norway :)
Have to keep Slepnar on the road, or off! ha!
I'm thinking you tested a 1.5 ohm coil. So if I have a pertronixs 0.6 ohm coil, it should read 0.6? On the other test I only got 8.5 through the center coil wire.
the 4 banger here has a 3 ohm coil, the 8 has 1.6ohm across terminals, the main windings, the from post to main plug wire, should read 10.5, 8.5 is low like the coil windings coating failed, and its skipping or shorting past some of the coil...
All Wright had the wrong resistance specs on their chart, they were switched around from what you taught us.
Like I had a dyslexic moment here or something on the web page? R for?
@@TEN-TIMES-HARDER Resistance specs on the All Wright chart on the coil are opposite of what you mentioned in your video.
Helpful video man. Used your tips for a boat with a V8 305. Helped a lot! Thanks
Most excellent, learned a shit ton I didn't know. 🖖🇺🇸
So after following your instructions which seem to be the easiest to understand on UA-cam I'm getting a reading of 8.25 which is a little lower than yours so would that mean my coil is bad? Thanks for any advice
yep! unless the battery imnyour meter is low l,ao
@erik the wrench I have a 2006 Volkswagen Jetta Gil and I don’t have any spark
I will find it in the comments later, I answer this question a lot, have to run to work now, the crank position sensor is not inside a distributor its on the block by the cam shaft end, same process as in the video
, just spread out
I have a 90 tbi in caprice i have fuel i only have spark coming from coil but no spark from distributor spark plug wire to the plug i changed the icm with a few new ones i still cant get spark to come out of spark plugs such an headache
well you have a bad distributor
very informative cheers man
Hey what is that spark plug thing called you are testing with
just an OTC spark tester, I got mine from the tool store , here is there online link www.toolmarket.com/product-spark-tester-electronic-ignition_30157.aspx
Lot of help thanks for share't good video keep up...Bless day
You too! I will have a lot more soon, got tied up paying bills lol
Very good video. Can you give me what the coil should measure at primary and secondary on a 73 ford 400 c.i.d. Galaxie? Thank you!
Stephen Kacin, all single coil v8 the same
Thank you Erik, but i dont know what they are? 1.5 primary, 8,000 secondary?
Thanks Erik. My 73 Galaxie is showing no spark to or from the coil. Seems to be intermittent. Any ideas where to go on this gremlin? This is coil # 3.
just so you know in case you havent figured it out yet. ford doesnt make a 400 ci engine galaxies most of the time have 390 engines. 400 is a gm engine.
Do you do motorcycle s , lot of us (me)struggle when they lose spark.
I was a honda suzukie dealer mechanic for a short while lol, i actually have some bike videos, a lot of videos, all on the editing bench lol..... its hard to find the time to put them up when im trying to get caught up with my customers lol
I'm less than a beginner, so my question is the values of impedance and voltage you talk about are standar values for lets say petrol engines, or do they vary accordingly with something for instance, brand or every engine is buit to run with a certain kind of impedance or voltage and those values are provided by the manufacturer.If myquestion turns to be a bit confusing, i mean how do you know the right reference values when it comes to electricity?
jose pontes , some heavy equipment might be 24 volt, and some old cars, pre late 60,s, where 6 volt ( and most have been converted to 12 by now)
But otherwise even semi-trucks and motorcycles are all 12 volt. (Or 14.6 running). The resistance on the coil will be the same for all v8 petrol, propane, alcohol....or close to it, oh, some old motorcycles and mopeds are 6volt as well... but we're talking 70,s
When doing leakdown test you will need to know the resistance of what ever part your testing, manufacturer specific according to manual, but if you buy the Haynes manual for obd2 codes they have general numbers that are good most the time...
also voltage divided by amperage equals resistance, if you know the amps...
I will make a video on leakdown test soon, I have so many videos I haven't had time to upload yet! Just been busy at work....
Many thanks for such a teaching answer. I'll be looking forward for those videos. cheers
jose pontes 1999 1997 Chrysler no fire what do I do
jose pontes I need to know if a 1997 Chrysler convertible it has no fire how do I bypass to the coil pack
jose pontes.
I have a 1963 buick 198 v-6. Car sat 20yrs. Replaced everything electrical- power at both sides of ign. Coil- no spark at plug?? Power good between points contacts- how come no spark on plug?
k, points has 2 hot wires. When the key is in the run position , a wire from the ignition switch with a ballast resistor powers the coil at 9.6 volts.
K, so when the key is in the start position it bypasses the resistor and gives it a full 12.6 volts to help it start.
so the ignition switch itself is very common failure, it can also be a bad resistor, or even the starter solenoid.
You will notice it has 2 wires. one is from the key to activate the starter, one is for the resistor bypass to start voltage.... so their are your check points, I have a wire diagram on www.bedhed.xyz/ih
so with key on, you should have 9.6 volts to the coil!!! if not u have bad resistor, wire, or switch!
with the key in start position, you should have 12+. if you have both, check your points or condenser, they are like 2 out of 3 bad from the factory now days!!!
so unless you have major problem like the distributor aint turning.........
@@TEN-TIMES-HARDER ok, I
Just got out to check everything I read last night. First thing I found is the ground from the engine to the frame is broken! Does it need to be grounded to start?
Next I’ll check the ignition switch. When the key is on I have power on both sides of the coil? Is that normal? Everything electrical is new, including the starter and alternator. Where is the resistor? Thx a million for your help
if the engine is nout grounded the distributoe is also not grounded!
also if its a new harness, and its not wired for points, it will burn out your points like every two months
@@TEN-TIMES-HARDER there’s no wiring harness in this car. It has very few wires. Wires from ignition switch, starter relay/solenoid- voltage regulator, that’s about it. I can see all the wires and they look ok, just the ground strap was broken. The next problem is no or low compression? I pulled plugs and squirted in each cylinder. Squirted the tops of push rods and valve springs. I have a weird rocker system?? It has a rod with springs bolted down over the top of the valve springs so there’s no adjusting the rockers? U seen this type before?? Thx man!!
Charge that battery and crank with that spark tester clipped on it. If the battery explodes💥🔥... you have spark. 😳
nah, lot of myths, they have merit, like the whole thing of batteries draining on the floor, thats from when they came in wood cases! Half of it is insurance company bs..... Did you know that a lap belt is better than a single shoulder strap, unless you have a x or two of them, its instant spinal damage and whiplash.... the odds of half this shit like your car running while pumping gas exploding, would mean every wire short on every car would blow up the gasstations or your battery.....
Hey any advice? I’ve replaced the ignition control module, ignition coil, distributor, and plugs with still no spark, I have a 96 f150 with a 351 Windsor and I’m running out of things to replace and money! Any advice would be appreciated!
With no spark at all? It could be your ignition switch, or a broken wire.
I mean if we are looking at rare things is the engine grounded? But I would do a leakdown test. Sometimes even the pins in the bulk connectors get pushed out... but you really need to prove every connection and eliminate the basics, is everything getting power, and shirts or false loads, is the ground good, is the ignition switch good, if you jump power to the coil from. Battery... heck in computercontrolled cars a bad battery can cause issues but yours sounds like a short or a bad part, it’s pretty simple, key goes on and coil/distributor get power,
Then key goes to start and everything but the coil/distributor loose power while the starter engages.
When camshaft turns it turns the distributor shaft by the gear. Then the rotor points at a cylinder and the magnetic pickup tells the coil to dump the spark at said cylinder, with some interference from the control module controlling the spark. And that’s all there is to it. So if the distributor rotor is turning, and your rotor is good, and assuming your new parts are good. You must have a short
ERIK THE WRENCH Turns out I bought a faulty set of ignition components, installed the original with the new distributor and crankshaft sensor and now she purrs first key turn, thanks for your help!
Thanks..this is great, but a lot to chew on. I'll work through each item you mention an report back.
Did you report back
must have been something simple lol
Ok, I am curious now. I just bought a boat with a Mercruiser 3.7 that has points. It appears that I can upgrade the point system to a magnetic pick up like in your video. Is the magnet pick up all that is needed with a direct connection to the coil or is there a control module somewhere in-between.
That's the cool thing about pertronix the control board is built in to the backing plate for the rotor! So all you need to do is remove galaxy resistor that is in line to the coils power.
See that's what that r terminal is on your starter. The points run on 9v, so their is a 3v resistor in series b4 the coil... so the when starting, the resistor gets bypassed and the coil gets full voltage to help start.
Oh that's all in the second video, no spark no start sokved!
Great vedio bro I learned so much!😁
i love to learn
Yeah that is definitely a good video thanks
:)
New Control Module and have found and installed new MAP Sensor and problem persists...with a twist...mis seems to occur only when driving down hill...power good up hill and on level roads. Everything i've read indicates engine cannot be re-timed because the electronics get in the way. So, if i set #1 at TDC with rotor pointing there, then hand crank engine to 10deg BTDC and lock down the distributor, is it correct to presume that the electronics will do the rest? One more consideration...i live at 7200' altitude and seldom drive below 5,000' altitude.
If it is an IH power plant, it gets timed off number 8cyl! the camshaft turns the opposite direction due to the cam is a direct gear drive, no chain....
Also at higher altitude you have to rejet your carb, but your computer should adjust on injection...should...
it is possible the injector is dirty or bad fuel pressure. so with out the backpressure from going up or level, it would show the lean symptoms more.... can even be something in the tank floating around.... filter... pump... the pressure regulator... so I would test for pressure... Also Map sensor must be clean clean clean and with map cleaner, if you got anything on it it will fail, also get the voltage specs and see if the map sensor has a broken wire running to it.... If you do not set the timing to factory usually you need a chip or a computer flash.... Not sure what your working with... how steep a degrade? the wrong gear even lol Are you getting any codes? even spark plug wires routed wrong can send false signals and trick the module! you dont need to adj mechanical timing for alt... You may need hotter or colder spark plugs if you have modified the timing, a colder plug will transfer heat faster out the chamber...
so is it a random multiple missfire or a particular cyl? random is usually from lean or bad timing.... can also have worn springs on the advance weights in dist or a sloppy shaft....
even if you disconnected the egr or messed with the pcv.... Egr actually was a way to trick emission test. see they lowered compression to pass, and gave it an egr, so that on idle its a lower compression... The the recirculated exhaust dont compress like the air, so it raises your compression under a load! might be bad... with out the pcv it will run rich if you dont compensate...
Where are the coils found? Also what was it that you tested for spark the second time?
FOLLOW THE WITE FROM THE CENTER OF DISTRIBUTOR CAP TO THE COIL.
So do you get lower voltage at the coil if your pickup coil is bad or damaged? What if the gap between the pickup coil and the reluctor isn't adequate? Could that also cause a drop in voltage at the coil?
The coil is charged like a capacitor right, straight 12-14volts. goes to the coil. unless its points then it gets 9.6v! As soon as it can ground out, and complete the circuit, it does. It does this through the cap and rotor and goes to what ever plug wire its pointing at.
