Cylinder #2 & 3 arent firing

[ghostmax301]

Well as the title states,for some reason my car is not firing cylinder number 2 & 3.

So far, I have checked for codes(none) cleared them, start the car for a little bit and check again(none related besides evap and egr and o2 sensors). I've changed the spark plugs and coilpacks and fuel injectors.still no fire. the 2 coilpacks are getting constant power and ground but on cold starts, the signa wires are get 0.10-0.12volts while the other 4 are getting 0.20-0.30 volts. And when its warm, the 2 bad ones get 0.00v while the other 4 are getting 0.01-0.02volts

I also tried running a wire direct from the ECU to the coilpack and still the samething..


can anyone PLEASE help me fix this problem?

ALL COMES DOWN TO 1 QUESTION

Which wire goes to the ECU to tell it which order to fire the cylinders in or tell it to fire the cylinders period?

If it helps any, somehow i blew the BATTERY fuse in the fuse box beside the battery.(fuse was replaced)

Im asking which wire controls them because i want to trace the wire to see if it burned up or anything.


sooooo many headaches

Are you getting fuel? When I had my 3.5 swap done, something shorted out the injector driver in the ECU and cylinder 1,2,3 werent firing. Injectors were fine, plugs were firing but the ECU would not send the signal for those injectors to open. When the ECU was opened up, there was visible damage (burnt). This may not be your case but its an idea.
Good luck.

well, the fuel injectors are firing but I pulled the coilpack out with the plug attached and it didnt spark.

THINK I FOUND MY PROBLEM(thanks to phmor)

now is this possible if my timing is at 15 degrees? Or does this mean my igniton timing is good but my cam timing is off? If so, i think i might know why my cam timing is off

the best way to test the coils for spark is to disconnect the crank pos. take a coil and a plug that u know works and hold the end of the plug to ground while cranking.

Ding! Ding! Ding!

Thats your answer!!
I know this first hand because it happened to me. I went crazy looking for the problem for a month or two. I switched out the wiring harness, checked and replace the CPS and CKPS because it had low readings. I suspected the timing maybe, but nobody knew and doubted the timing issue... and finally, a freind and fellow orger emailed me that same site, and BADABING!!!

I had found that my Unorthodox UDP stripped and the Crankshaft dowel key tore a huge gap into it, causing it to rotate a few degrees clockwise. The dowel key was also bent like nothing I have ever seen. Luckily, the crankshaft had no damage to it whatsoever!!

[ghostmax301]

well.I got the problem fixed thanks to that link..THANKS! it should be sticky'd.

anyway,it wAs my cam timing. was off ONE tooth. fixed it and the car runs great now BUT I do have a question about the crankshaft dowelpin. I should go ahead and replace that now shouldn't I before it gets too bent up? its bent a LITTLE now but the pulley is on TIGHT sooo, wat u think

[i2vicious2]

i think u should swap it out.....

[915Max]

swap it out!! Its bent already... any more stress will cause it to completely strip, and you might damage the actual crankshaft... you for sure dont want that!!!!
