- Huntin season is comin quick! Gotta keep my truck running. I put in a new 5.9L and played hell trying to get it tuned right. This vid will hopefully help get your truck up and running faster than I got mine up.
I realized i couldn't use a old school timing light on my 99 dodge. So I just moved the distributor around untill it did the best burnout. Fucking MINT.
Thank you thank you thank you .AND GOD BLESS YOU 4 days after I get this motor installed swap out from a Durango to a 1500 quad cab get on couldn't get nothing to work put it to the V8 mark matching up with the TDC and it ran God bless you brother thank you brought tears to my eyes to hear this motor run
I am so thankful
Dude, you are the Greatest of all Mechanics & Video Post. I've been trying to get my truck started for 6 months now. I can't think of enough words to thank you. You are the "Master Mechanic" above all others.
Explain how this helped you start your dodge? He is adjusting it while it's running

Are you having issues with you engine? Are you just trolling? What's up with you?
@@spiritoflight1375 I'm currently working on a 2002 dodge ram 3500 with the 5.9
Customer told me the van drove great last week. Parked it last Friday and we had a rain storm come through last Saturday. Customer has told me the van has done this before and they usually let it dry out and it starts up and run just fine. Now the vehicle will crank but won't start
I get to it Monday and check for fuel and spark. No spark but I didn't have any codes on the dash. Cycled the key 3x to get a p done on the dash after the odometer reading.
I have verified Cam and crank sensors work.
I am using the snap on ethos edge scan tool and I can ready all the activity. I have checked for spark from ignition coil to the spark plug itself and it checks out. Used the scan tool to activate the injectors. Verified Crank and cam signals.
Based off this video, he is checking it will the vehicle is running which is why I gave my comment. Can this be checked if the vehicle is not running? Or does it have to at least crank?
I don't see how anything could have changed between the van being parked on Friday to Monday a no start but has everything to run

I bought my vehicle from a friend who couldn't get it smog. Good price!
My vehicle was parked for a long time. Having been parked for a long time with a dead battery caused the computer to lose it's memory. The battery was dead for quite some time. Did everything I could think of to get it running again. New everything. The video referees to "fuel injector timing" or "initial timing" using the V8 stamp to set to #1 spark plug than the computer will adjust it from there. This worked for me it started right up.
Before finding this video it was hard to start, once in a while it started but seemed like only some cylinders were firing & some not. It was horrible.
@@spiritoflight1375 ok, so you just have to turn the fuel synchronization on from the scan tool as long as the #1 is at TDC? Watching the video, the car was running.
Dude ,man ,Bro Your awsome I replaced my engine 5.9 and could not get it running for nothing nor can I find information when I found your video is like a god-sent made perfect sense to me bold you directions and shebang she fired right up I was really discouraged before I found your videoseems like a motor that I put in my truck came straight from Pick-A-Part no compression or anyting leaving me to believe maybe I made a huge mistake but the engine runs great and thank you again man
Hello UtahHunter from Okie MoPar nut. That is not called a fuel sync it is called a camshaft position sensor & it's only purpose is to tell the ECU what cycle the engine is on (exhaust or intake) so that the computer can properly time the fuel injection cycle which, once the engine is running , is timed off of the spark trigger (pickup coil) on the bellhousing. Dodge magnum engines use a tone ring on the flex plate for auto trans & notches on a flywheel on stick shift units. Instructions straight out of a 1996 Dodge ram 3500 van, 5.9 engine. 1)Rotate engine until #1 piston is coming up on compression stroke. Align tdc mark on the harmonic balancer with the timing mark on the timing tab. 2)If the oil pump drive has not been removed install the distributor & align the rotor tip with the notch on the CPS labeled CYL NO.1. 3) install & tighten hold down clamp 3) Install the dist cap & make sure the wire sequence is correct for the firing order 4) Start & drive. Setting the fuel sync? Is that a GM term? According to an article in MoPar Action magazine on this subject the tech editor says that you can unhook the cam position sensor once the engine is running & it will continue to run just fine until you shut the engine off. It is only necessary (the CPS) for startup. I'll try that tomorrow to see if that is true. I have rebuilt a 3.9 V-6, a 5.2, & a 5.9 (the van engine) & followed this procedure & all performed as advertised. Fuel sync?? No such thing on the Dodge magnum engines.
Update: Ran a test. Started engine (already warmed up) & unplugged the cam position sensor. Engine will run just fine. Shut engine off & tried to re-start, no go. I can only surmise that the purpose of the CPS is to tell the computer what cycle the #1 cylinder is on.
@@larryhutchens7593 i was wondering about this too, I just rebuilt my 98 5.2L and I set the #1 CYL at TDC and dropped the distributor in and everything lines up.. I have the Haynes manual to this truck and this is what it States.. but nothing about "fuel synchronization". I believe you are correct on this subject because I have searched aawell.. I'm a mechanic and it just did not make sense to me the "fuel synchronization". Like you said the fuel injection is preset.. the computer relies on the CPS to determine what stroke the engine is on.. when everything is set the computer will adjust the timming on its own.. my chain was extremely strethceh and skipped a tooth and somehow the engine was still running decent.. sluggish.. but decent... It auto adjusts to always be on #1 TDC
@@zorans5200 Small block MoPars (the 3.9, 5.2 & 5.9 are small block) have a fairly long timing chain. I always install a timing chain tensioner when changing the timing set. Most 3.9s come from the factory with one. Summit & Jeg's have them.
@@larryhutchens7593 there is no timming chain tensioner on my 5.2L,. Unless there is an after market one for purchase
Just two cogs and a chain
@@zorans5200 They are after market. Last one I got was a Cloyes. I remember rebuilding a #.9 in a 2000 van & it had one that appeared to be factory. I use one on every small block rebuild, they are fairly inexpensive & easy to install.
Thanks for the info! It works. I replaced the lifters on a 99 dakota 5.9 and had the distributor out, when i reassembled it it barely ran. I followed your instructions and it runs like a top! Thanks.
Mine was off by 16. Wondering why it vibrated and seemed to redline at 3500rpm. Did this “trick” as it were and now I’m dominating again! Thx man
Many thanks for this info! This has to be saved to my favorites!
I tend to overlook things and hang on every word when getting instructions. Just to clarify things you don't line up TDC on timing chain cover with the letters V8, use the recessed timing mark on the balancer. I know that sound stupid but I researched this for a half a day just to make sure. I'm a mechanic, but im saying to myself, "he said to line up where it said V8 to the TDC mark", lol! I got it and thanks for the video
Alfonso Demagistris why set it at v8
thanks Alfonso, I'm adjusting fuel sync and I set my recessed balancer line to TDC, was super confused when he said v8 mark to TDC lol
Alfonso Demagistris
Both you guys are not following what the master mechanic said. It worked for me. I've tried endlessly what traditional proto call would dictate. You should listen to what a real master mechanic can share. "Inital timming" for timing to fuel injectors. (V8 mark) everything works togather now.
Tugboat mods. Thanks for the plug
Mine won’t even start, not getting enough fuel. No V8 mark on my balancer, but ignition timing seems to be spot-on. It’s a 96 5.9
thanks for the info! i see you got a CB bracket you talk skip ? Bayouboy Swamp Lands Louisiana skip shooter here back in the 90's before i got on computer year 2000
Thank you for this video
Thanx for your info!!!!! I will going to try it and let you know Regards Jimmy From The Netherlands
Thank you !
I hope you see this, what if the scanner dosent change number, not reading anything. Snap on high high dollar scanner. We get it to the rpm/ degree screen but nothing.
When hooking up your O2 sensor I have a 2001 Dodge Ram you have a black or grey and two whites obviously the black and the gray go back to black and grey but does it matter on the witch two go back together long story short my dog got underneath my truck and chewed out a bunch of wires and I'm splicing them back together and the O2 sensor was the only thing I wasn't sure of
Just found some rodents chewed my drivers side plug wires, crank position wire, and cam position wire (fuel sync in dist.). Can I just drop a new sensor in or do I need to muck with this shit?
I have a 98 3.9 it fluctuates from 24 to -11 I have checked timing chain slack non have replaced cam and crank sensors cap rotor and looked for rust relucter on flywheel runs rough and backfires
Do you like that scanner? We have a similar Modus Edge and we do not like it! We always fight over the Autel...
You are wrong because i have the mopar repair manual and it says tu line up a mark the balancee with tdc not v8 with tdc
Ignacio Celaya
Dude, this is initial setup sequence for fuel injector. It worked for me. Ben trying to get my vehicle started for 6 months, new parts, tools, testing equipment. This man & video are right on.
What scanner did you use for this?
I need help I'm trying to fix my truck I'm confused do you lined up v8 to tdc or not?
Why are we setting fuel sink
Question…. I have a 97 5.9 ram 4x4… I put a double chain with 4degree advance/retard option I put it 4degree advanced… I have a code stating intermittent loss signal from crank or cam… I got her running pretty good by ear with what I now know being the injector pulse only but she runs decent but slightly brakes up and studder/stumbles literally a second then runs fine … ? What should I do … it’s a stock motor don’t know about mopar motors I’m a Chevy/ford guy
Mine fluctuates between 0 and 4 I left it. Is that okay?
Should be ok.
love the tugboat! im figuring out my fuel sync right now, 2 years ago i had lifters ticking, or an exhaust leak, so i tore it down and replaced them, while i was in there i took the cam out and was going to put a better one in and then life happened, the truck was moved without the cam in, whats the best way to get everything synced back up?
Carl Daenzer just make sure all your timing marks line up correctly when you put the cam back in and you should be fine.
So you don't set o on the pully. Has to be v8
How much was your high dollar reader?
Eric Phillips I'm not sure, I borrowed it from a friend.
Very informative but you did not mention if TD con compression stroke ? Because when I set the engine to DTC as you suggested and 5v at the connector , my cylinder #1 is in exhaust TDC and the engine runs but I can’t set the idle, it jumps from 600rpm to 1700rpm .
Is my distributor internally faulty? Please comment
Yes I believe it should be TDC COMPRESSION stroke
Take around to the compression stroke.
what was your truck doing for you to have to do this? reason I asked is I bought one and it runs fine shifts fine but gutless and hard as hell on fuel, 8 to 9 mpg. cats gone, every thing tuned up all sensors working and plenum gasket is fine. so I wonder could this problem be for me?
roy cook I put a new engine in mine so I had to do it. Can't hurt to check yours. they can move over time
Ok awesome, I bought this one and they had just put another engine in it, so I guess they may have mucked something up. they were having trouble, when I bought it was turning at 1000 rpm for no reason, found out they had messed with the throttle cable stop set screw. so who knows? they may have had the disturber out And messed something up with this. like I said it's gutless and hard hard on fuel. Tks for your help. great video by the way.
What was the problem?
What year is this for?
Literally said on the video it's an 01
What about obd1
Worst piece of junk ever!!!
What scanner are you using?
