2nd & 3rd cylinder not getting spark.....why?!?!?!?

[1g4g63t]

like the title says....

on my 95 4g63 2nd & 3rd cylinder are not getting ANY spark..why ? ?

here is what ive tried so far to try and fix it...

- change the spark plugs
- change the spark plug wires
- change the coil pack
- change the ignition control module

i did all that and still no spark ... why ????!?!?!

You might also want to check the coil pack connector (on the engine harness side) and the ECU for leaking capacitors. Read this post:

You may want to check you CAS and also check your ecu for leaky caps. You can test your power transistor with a voltage meter. If you have a repair manual it gives instructions there. Let me know when you fix it.

Yeah, I just had a 1g swap like a month or two ago, and mine started not getting spark to cyl 2 and 3 as well. I have been reading and reading, and also looked in the manual, and it says the same thing. I am gonna try this and i'll post my findings. I am thinking its a bad power transistor though, bc i also have a AEM EMS... i hope to friggin god that that isn't the prob.... i don't need to be replacing a $1200 ecu damn it. Also, has anyone else had the problem of the tachometer fluttering when this is happeneing too? Just curious. Good luck to all!!!!

got around to looking at it today...... i followed the correct prodedure according to the book, and sure enough........ the test for cyl 2 and 3 failed. So, all i need to do now is source this damn transistor. I think they are like 110 new from autozone. Gonna try a junk yard tomorrow, but if nothin else, autozone it is. I'll let you guys know what happens.

finally found out what the problem was..on 2g's the cam angle sensor has its own cam gear ( i didnt know that) but i had it installed and the car runs perfect now !!!!
