No spark on 3 & 6

[DarK_sTyLe]

Bad news changed the PTU AND IGNITION COILS and still no spark on 3 & 6 could it be tje ECU

[Jimvr4]

Yes it can. The ECU should provide a low voltage signal to control the power transistor (PTU).

Do you know about the IC105 chip that controls that coil? How can i repair it?

[Jimvr4]

DIY is probably not a great idea

[Emilie@GZP]

check the ECU

check the ECU

i opened my ecu it look good not leak capacitors or anything but this is so weird because am 100% sure its the ecu sometime tomorrow i will replace it with a friends ecu and see what happens

[DarK_sTyLe]

also is it possible that my car is burning them or something.... how can i test that?? because the first ecu the car had stopped working, the thing with that one was that it was no spark at all coils after that i bought one on ebay and it was fine until now everything works except for that coil 3&6 hope this helps

ill say it once more just to toss it out there, have you checked your timing? just do it, it takes the removal of a wheel and the covers, and a breaker bar.....could save you a few hundred in parts.

I thought we covered that.... Please explain your logic as to how cam timing could possibly have any effect on a 91-92 car...?

my car does not have the sensors and i am 100% sure my timing its correct because before i replaced my ecu i did the timing belt and the cam gaskets but ill check the timing tomorrow
