PATHRIDER Posted March 3, 2010 Share Posted March 3, 2010 hey guys I was finally able to fire up my pathy thats been sitting for about a month now but one problem iss when i was going to set the timing it was way off Before i started her I pulled the distributor and replaced it with one I got off of a 94 pathy at the junkyard and the ecu also came from a 94 auto When i installed the distributor I followed my1paths instruction on installing it. I have the mark on my crank pulley at 0 and dropped the distributor in making sure that the rotor is facing spark plug 1 which it is. started her up and it took a couple of crank before she fired up and it runs great except with a little hesitation that sounds like its choking a bit so I figured it must be cold still , I let it warm up for about 10 mins and checked the timing and it is about 180 degrees off or its passed the 30 mark on the crank pulley by about 6 notches (0.5.10.15.20.25.30) It surprised me that it ran well considering the timing is way off. My question is could it have skipped a tooth or so on the belt? I did my timing belt 2 years ago and hardly drives my pathfinder could the distributor be a defective one? should I let it warm up some more ?

nunya Posted March 3, 2010 Share Posted March 3, 2010 COuld the dist. be in 180 off? Like on the exhaust stroke instead of the compression stroke? Someone will correct me proably, just thinking openly Link to comment Share on other sites More sharing options...

Someone will correct me proably, just thinking openly You might be correct bud. when I manually turned the crank pulley It has the real springy feel to it at first then it passed the 0 mark (thanks to my drunk buddy) So I have to crank it clockwise again and the second turrn it is a lot easier and soft to turn, When it has a springy feel when cranking the crank pulley manually it means its on the compression stroke right? i bet thats what the problem is..I didnt pay attention to exhaust and compression stroke when I dropped the distributor in and lined up the rotor with the number 1 plug Im going to pull the plug out tomorrow and make sure im on compression stroke before i line up the rotor to plug 1 Compression stroke it when the cylinder is up right?

nunya Posted March 3, 2010 Share Posted March 3, 2010 #1 Will be at TDC (top dead center) at both compression and exhaust iirc... it's which valves are open that are different. Again, someone a little more knolidged on this particular subject should chime in soon Link to comment Share on other sites More sharing options...
PATHRIDER Posted March 3, 2010 Author Share Posted March 3, 2010 (edited) #1 Will be at TDC (top dead center) at both compression and exhaust iirc... it's which valves are open that are different. Again, someone a little more knolidged on this particular subject should chime in soon Im thinking that its just like when we do the timing belt that the cylinder has to be up (compression stroke) before lining up the marks on the belt. It has to be on tdc in compression stroke Trick that i was told when I did my timing is pull out plug 1 and stick a long zip tie in there and wath for it to go up then its for sure in the compression stroke..Thanks man Edited March 3, 2010 by PATHRIDER Link to comment Share on other sites More sharing options...
Precise1 Posted March 3, 2010 Share Posted March 3, 2010 Yes, it must be on the compression stroke, TDC cylinder #1 (the forward most on the passenger side IIRC) and the dizzy rotor should be pointing at the front passenger corner IIRC). Best way to tell compression stroke (springy one is probably right) is to put your finger over the plug hole and crank the motor. On compression stroke, it will push air past your finger... I have to ask, only because I have done it, do you have your timing light clipped to the right plug wire?? #1 again... B Link to comment Share on other sites More sharing options...

I have it clipped on plug 1 Im going to double check on it today and make sure Im on compression stroke on plug 1 when I reinstall the dizzy Im pretty sure I did it on exhaust stroke thats probably why its 180 off..I will keep you guys posted. W I took a short clip last night on how it runs just cant figure out how to upload the vid Link to comment Share on other sites More sharing options...

PATHRIDER Posted March 5, 2010 Author Share Posted March 5, 2010 I reinstalled the distributor on compression stroke with the rotor facing plug 1 and now it wont fire I know I have the markings on my crank pulley correct.. We cranked the motor by hand and took a small dowel and stick it on plug 1 and watched it go up and down while I have my buddy turn the crank pulley and soon as we get to the point where the dowel is up I lined up the mark to 0 and dropped the distributor in and its facing plug 1 what else could I be doing wrong?
