s4 install, cranking but not firing... help please
Ok , so i installed the s4's today. Followed everything on the jwt instructions.
-Got the crank to TDC - cams facing toward the engine #1 at top
-tied wraped gears/chain
-checked everything...
-Intake keway is a 10 oclock- exhaust is at 12 oclock
-there are 20 ''lobes'' on the chain between the 2 marks.
-intake gear have 5 tooth to the mark
-exhaust gear have 9 ish tooth to the mark.
-all at TDC
-disty fires, all plugs are right where they should be.
I'm confused here. Why is it dosent firing. I pulled the VC again to confirm all of the above and it is spot on....
Help please.
I passed the day dooing this and redooing it. I dont see what is wrong.
try moving the dist. all the way forward and backward. it is possible to jump a tooth at the crank. if it runs with the dist. adv. or ret. thats what happened. also a better way insted of the wedge is to take out the tensioner. good luck
I guess to see if i skipped a teeth on the crank sprocket, i could put something in/on the #1 cyl. and by rotating the crank see if it is really at TDC comparing with the mark on the pulley...
If i really skipped a teet on the crank i'd have to pull everything apart to set it right?

This is interesting because I have perfect cam timing as well, but I have to advance my timing almost all the way advanced. One theory was that my crank had skipped a tooth.
My car runs and starts fine though.

you dont need to rip everything apart just take the tensioner out 2 10mm bolts and let the chain go slack then set your crank at tdc and lock it then set your cams at 10 and 12 then pull your chain up to the sprockets make sure it is on the crank and then apply chain to cams then refit tensioner then rotate engine twice by hand to make sure all is sweet then put back together and bobs ya teapot

You say the distributor fires, then you say it's not firing. It looks like your cams are lined up correct from the info you gave, so I don't think that's the issue. If you skipped a tooth on the crank, the crank pulley would still be correct when it showed TDC, since it's bolted to the crank and doesn't care about the chain. Remove the distributor cap and verify that the rotor turns when you turn the engine over.

hold on a min cant the shaft on the dizzy be put in a 180 degrees out because i had a ae92 corolla with a 4af engine and i put the dizzy in with the shaft 180 degrees out accidently and that dint fire
-Got the crank to TDC - cams facing toward the engine #1 at top
What do you mean "cams facing toward the engine"?
@ TDC, cyl 1 intake cam lobe should point to firewall, exhaust cam lobe should point to front of car.
Everything else like this, except start w/ dizzy adj bolt in the middle of the slot:
^slack in chain since tensioner was not installed yet.
Better pic to show cyl#1 lobes, int facing firewall, exh facing front of car:
*edit - changed to larger pic*
oh no ignore that one looking at the wrong thing lmao i mean the shaft on the back of the dizzy that gets drive off the cam try spinning it a 180 degrees and pop the dizzy back in if it will go in cause i might be wrong i have not done that much with an sr20 before but that is what happend with my corolla
yeah i kinda messed that one up lol i wouldnt worry about the timing then lol just concentrate on the distributer it is it popping or out when turning over?

I posted pics for reference, for qctuner, the original poster.
ok i took tics to get you an idea of my timming...
Lobes on cam facing ''outwarg engine
Cam gear teets count and 10 12 oclock
Crank on TDC (a lil off but for example it is close enough)
I Checked if the rotor turns and yess it turns, manually. Maybe it is ''popping out when cranking? Tried turning the disty the 2 sides. At a point a got some pof pof, but not for long. Shure the engine is flodded and i need to let it rest.
You can see a LiL slack on the chain when at TDC... But everything seems in order to me.
If i'd had a teeth off on the crank, i guess it would be no prob since i'm at TDC, cams and sprockets and teeth count is ''spot on''...
-Another thing i tought is that i just changed my TP values with my old cams prior to the cam swap. Would it be possible that it would be to rich at startup to get fire??
not to sure but i dont think it would make it run rich so its flooded take the plugs out crank it over a few times and leave for about an hour dry you plugs and check there giving spark if so stick them back in and try agen its not immobilized by any chance is it
Immobiized you mean siezed? No its nowere near hot since it didnt fire at all...
My VC is off now, plugs are off for breething. Cant crank it right now.
I just want to be shure from your experiences that my timming is good. I'm F/%king tired taking VC on and off for nothing.
I think everything is wright where it should be but with the pics maybe someone will see something...
I really dont get it, If you tell me my cam/crank timming is good i'll put the VC on i hope for the last time. Then i'll figure out from there. I just dont want to take it off again if everything seems ok...
i ment immobilized as in security an immobilizer i really cant see out wrong from your pics only that your crank timing was out a bit but you already know that i would just set it perfect anyway *** but i dont think this would be coarse for concern. i would just leave it over night mate and grab a beer cause cars can be really stressful sometimes
Everything is fine, execpt that my rotor on disty in pointing more upward like near the #1 cylinder wire connector....
at TDC, the rotor should be pointing right at #1 cylinder wire plug.
On lowport dists #1 is UP
I think your cam timing is fine. Did you crank it over by hand a few times using a socket on the crank bolt and a friend to watch?? Maybe re-install the distributor and double check everything that would cause it not to start like battery, fuel, spark etc...
