Thanks for the video Ben old school GM mechanic over 50 years. Did tuneup on 99 Escalade they left distributor loose last time it moved on me when installing new cap and rotor wires. Got finished started right up but then kicked a camshaft and crankshaft Coalition code. Set it like the video now is dead on timing great video
You know, I had an old college auto repair instructor in 1974 that was just like you. I always thought that if I could be half as good as he was, i would be doing good. Now if I could be half as good as you, I think I would be an awesome backyard mechanic. Thanks for the videos. They are all amazing.
Holy crap balls, I spent 3 years learning this in college and never really understood it until now, now I know how to read graphs properly........thankyou
Thank you for making this video so easy to understand! I've watched others and they just mumble, talk a lot, or not enough to make it understandable. Now I can try it on my project truck! Thanks again
Just fixed a no-start concern on 96 GMC 1500 5.7 and P1345 popped up on the Pegasys. That's what I thought I was gonna have to do- reset ignition timing. No big deal haha. Have had to do it a couple times on my S10 4.3 What really helps is if tye distributor housing is square where the hold down sits- grind that thing down with a roto bit til its just round enough to rotate in the hold down while you're setting the timing.
great help, the van I just bought for work threw the check engine light as Soon as I drove off, seller said he'd "pray it worked out for me" lol. I was told intake gasket was just done, I assumed he didn't time the distributor right, and I was correct. thanks to your video I was able to fix p1345 code.
by watching this video...it will show you how to do it. You have to set your engine to tdc. then install your dist. once youve done that, this video covers the rest. tdc is your base timing as long the distributor is set right.
Didn't have a lab scope did tuneup distributor was loose take the code for camshaft crankshaft coalition. I just have a small scanner but look at the timing and you can get it Dead on adjusting distributor and watching timing adjustment on scanner. Works great if you don't have a lab scope use a cheap Harbor Freight scanner and it worked great
Ok I did what you did and I can’t get no further than 6 degrees per the scan tool. Distributor was placed in with cylinder 1 on TDC. Now I was calibrating it and it was at 17 and it ran smooth. the distributor wouldn’t go any further than 6 towards the drivers side and touches the intake. It shakes and doesn’t idle smoothly like it was at 17. Could it be possible that the timing chain be off by one tooth?
Thanks for the video my thoughts are I have more issues on my 1999 GMC K2500 Suburban with 7.4L engine my check engine is not on ? Anyway I just replaced the Mass Air flow sensor , Idle Air Control motor , Throttle Position Sensor - these are all on the Throttle Body - Engine starts hard & when I do get it to start it falls on it's face if I dry to drive I couldn't even get out of my driveway I must be missing something big time ?? Any words of wisdom from a master would be much appreciated Thanks
Here’s my problem, according to the scanner, my timing was 16 degrees off advance. I rotated my distributor one notch and now according to the timing light, I have to turn the advance dial around to 25 degrees to get the marks to line up at the balancer and tab. I have made sure that the rotor button is pointing at number one at TDC but it’s kicking out P01345 and popping out of the tail pipes. Any idea?
Do those scanners plug into the odb-ii port? What scanner are you using and what do you recommend for a home diy person? Thanks for all your videos, they are great.
I have a 96 gmc and the spark advance shows negative 20. Ive tried dropping distributor in a tooth back but still have negative numbers. Ive tried setting the harmonic balancer with line before notch on tab and still cant get positive numbers
How would you recommend adjusting timing with a tuner. I'm getting a ckp code but having violent mifires leading to hot engine stalls. Only with my plow on. I like your video to the point I hope you have time to respond
Hello, can you give me some more specifics, what your experiencing, what you've done or found. By plow I assume you mean snow plow? And when you say with the plow on you mean when the plow is activated by your switch and moving, and not when the plow is simply mounted and not engaged?
@@realfixesrealfast when plow is not moving but the weight I believe is the factor. My plugs are gapped wires new. My crank code is Consistent. Only stalling while engine fully warmed up. I've tried a lot. What else do you need. Thanks for responding
My 1999 Tahoe is throwing the P1345 code and I guess the timing is so far off, it won't even crank!! So yes I'm wondering how do I set the timing with it won't even crank!!?
im having this same problem what type of scanner would you recommend does is have to be one of the very exspensive types i have a craftman 87702 i bought from sears is it capibile of doing this
How would this be done on a Vortec V6 .from what i found you cant turn the distributor to adjust the timing . only line up the marks in the crank balancer .
+keving52002 I asked this question months ago but got no reply. When I replaced my distributor I never got the code, but I would like to know the answer to the question on the V6's anyway.
Mr26Huffy I can understand why no response was given to that answer .After doing some reading i found that the timing cant be adjusted on the vortec 4.3. first the timing can only be set my lining up two set of timing marks on the balancer on the crank.the only way timing can be off is from a previous repair ,that involved the removal of the distributor and the teeth are off by one or two. or the timing chain develop slack in it over time.
+keving52002 That was my assumption but I wanted to make sure. After all what is the difference between a 5.7 and 4.3 except minus 2 cylinders? It is curious that the V-8 would require 1-2 degrees of fine tuning and the V-6 not.
+Mr26Huffy the only difference is on the 5.7 the destributor can be rotated and on the 4.3 it won't ,if you loosen the bolt on the 4.3 it will not rotate.
I know this is a year late but you can file off the plastic where the hold down is so the distributor turns freely. Just be careful not to file through or you'll have problems.
Can you use a timing gun for that make 97 chevy 5.7????? Please help i have same trouble code P1345 or do I have to take it to a dealer or a certified auto care shop to get tuned?????
No you can't use a timing gun. If you watched it you would of seen the 'timing gun' they used is a little more sophisticated. You have to have a scan tool or take it to a shop.
I got a bluedriver scan tool and idk if I can use it to set the distributor timing it has a timing advance for #1 cylinder setting to see what its reading
On my truck (1997 4.3L Vortec) there is no adjustment on the distributor, only the slop between the hold down bolt and the distributor clamp. That is all the adjustment there is. Is this what you are working with in the video - this small amount of adjustment? Or are the 5.7L engines different and have more of an adjustment (like a slot in the hold-down of distributor)? Thanks.
I have a 98 vortec 5.7 the hold down on the distributor won't allow it to turn for adjustment. What do I do to synch the cam and crankshaft position sensors
How can I turn the distributor if the hold down is a one position type how do I set the timing on it? What am I missing here because I cant turn the distributor because of the hold down clamp
gokblok he is setting the the timing of the spark of the distributor to match the timing of the intake and exhaust valves when both are closed at the combustion stage and the number one piston is at the top dead center position for a complete efficient combustion process. The most sure fire way to find top dead center on the number one cylinder is to have the relative valve cover removed. 1-Bar the engine over in clockewise rotation. 2-Rotate until you notice both valve springs are not compressed and both rockers can wiggle freely. 3-At the same time check that the timing mark on the vibration damper aligns with timing mark on the engine. 3-Mark the location of where the number 1 position of the rotor would be on the distributor so that it can be installed without the cap for reference. 4-Install the distributor with the flat of the front parallel to the angle of the intake. Make sure that the cap is lined up with the mark on the distributor. If it drops right in. If it does not, install the distributor in on the cam gear with the cap aligned at the mark. The distributor will not be completely set into the intake. Its ok. Bar the engine over until it drops in on its own . 6- repeat the process of finding no 1 TDC confirming that the timing marks are aligned and that the rotor matches the mark for no 1 on the distributor. Good luck to anyone needing this info.
@@ahumm8280 I think hes asking what is he physically adjusting which is my question too.. am I loosening the hold down and rotate the whole distributor?
Great video, but my understandings was that this type of distributors can't be rotated due to a type of hold down clamp that holds the distributor, how did you do it? Thank you
There are two types of hold-down clamps. Most aftermarket (and some O.E.M.) distributors have the non-adjustable type. Best thing to do here is find an adjustable kind from a junkyard OR get a new clamp from NAPA, O'riely's, Pepboys, or Autozone. Good luck sir!
you're off by a tooth or two. Pull the distributor, make sure you're at TDC, then double check the settings and reset the distributor. Rinse and repeat if wrong.
My 1999 Tahoe is throwing the P1345 code and I guess the timing is so far off, it won't even crank!! So yes I'm wondering how do I set the timing with it won't even crank!!?
I had a 99 2500 7.4L that would not start with the distributor rotor pointing to no. 1 TDC. The distributor had to be 2 teeth in the retarded direction to get it to run. Then, we could use the scan tool cmp retard pid to adjust the cap. Isn't there a standard timing that you drop the distributor on in order to get it to run?
wrong! did you watch the video?? he was adjusting the timing with his hand using a scan tool instead of a timing light. if you cant get it to 0...then your off by too many teeth and have to pull the distributor.

if you can only turn it a little way then you may need to slot the bolt hole a little to get what you need on it..

Man I’m so scared to do this to mine. Mine shows positive 22 and above running. Scared I’m going to mess something up bad
what scan tool brand are you using?
What machine is being used
nice video, keep doing them!
Hello, i have honda accord 91 has engine light on, where can I connect the scanner tool? thanks
OBDII is only 96 and up
You can't you have to use the flash plug under the hood and count the flashes of light on dash then look up the code

do i have to reset the codes afterwards?
What would be the cost for this to be done
What if your timing a motor with 160,000 miles? Still +-2°?
Doesnt matter the miles. 0 degrees to -2 degrees is in proper specs of the timing.
Does it matter which way you turn the distributor?

I changed lower intake and switched to mpfi no engine light but lacking in power. Will it need adjusted if there are no codes coming up?
0:34 it says YOU CAN NOT ADJUST THE IGNITION TIMING!!!
By timing light u cant. You can with a expensive scan tool.
you're off by a tooth or two. Pull the distributor, make sure you're at TDC, then double check the settings and reset the distributor. Rinse and repeat if wrong.
What about when the truck won't start?
My 1999 Tahoe is throwing the P1345 code and I guess the timing is so far off, it won't even crank!! So yes I'm wondering how do I set the timing with it won't even crank!!?
Phillip Davis Get a Snap-on scanner and adapters and cartridges and manuals. Also get the 120 volt adapter to check test results away from the car.
Marty Stevens Your gonna need a loan from the bank.
Physically the distributor has to be very close if it won’t start you are probably way off

97 350 DIST NOT ADJUSTABLE!!!!!!!!!!!!!.
How the hell do you "adjust" a non adjustable distributor !!!
use a drill to lengthen the opening where the bolt sits, that way you can move it slightly
quiero aprender de ustedes pero lamentablemente soy latino espero que me ayuden a como traducirlo
I cant set on my 5.7
wrong! did you watch the video?? he was adjusting the timing with his hand using a scan tool instead of a timing light. if you cant get it to 0...then your off by too many teeth and have to pull the distributor.
Most likely no. Take it to a shop.
Timing is not adjustable. Computer controls the timing from the sensor readings.
