Car has no spark and no codes popping up. Changed ignition relay still no spark, but the check engine light blinks five times when I put key to on position. What could that mean?

Hello,

It sounds like the PCM is bad but to be sure lets make sure its getting power and grounds. Here is a guide to help you check with the engine computer wiring diagrams so you can see how the system works:

Here is the location of the PCM I would check it for water damage. Then try a used/rebuilt computer to see what happens.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken
