Will a defective PCM cause a misfire on one cylinder
If PCM is bad it would give a random misfire,check the compression on the cylinder that is not firing,may have bad valve on it.
I have already pulled the new coil and put a new plug in it and grounded it and then started the engine...but no fire to the plug from the coil...could that still mean possablility of a low compression problem? If low compression can cause the coil not to fire, I will run a compression check in the morning if you still think so
No,if you do not have fire at that plug,there is a issue,may be bad spark plug wire,
