My car has been having missfire and cutting out/stalling issues. Wasnt getting correct spark out of 2 coils, although the coils were ok themselves. I eventually limited it down to the ecu (Pretty sure, I checked just about everything first) Anyway I got another ecu and put it in and no check engine light... I tried cranking but nothing. I put the other ecu back in and no check engine light aswell. I have checked fuses, (unless theres any that I missed). Is there a way to check the ecu's power? and grounds? I have tried to do what I could do with the tsrm, but I am a little bit confused and have gotten frustrated with it. I cant get these ecu's to power on. Anyone have simular issues?
