Hello, my name is***** for the question. I would not just replace the PCM. Can you tell me what brand coils you are using?
Let me take a look at these and I will get back with you shortly.
Thanks. Those should be fine. Have you checked to see if the power to that coil goes off when the ignition is turned off?
Thanks. Did you measure the signal wire at the PCM to see if it was high there also? If it is then it needs a PCM. If not then you need to find the short.
Is that the white/blue wire that shows 5-6 volts? If it is then you need to test the same wire at the PCM with it plugged in. If you show the same voltage there then the computer is bad.
