Without knowing the exact codes and what the vehicles symptoms are we cannot answer that question. It could be anything from a blown fuse shutting off parts of the PCM to shorted wiring or rodent damaged wiring.

Please list the codes and symptoms and we can try to assist you.

I good way to approach this problem is to clean all codes then without starting the engine turn the ignition key on and read the codes. If all codes are present then it sounds like the PCM has gone out. You in Texas by any chance?

Here is a guide to help you read the codes, codes readers are cheap nowadays:

If the engine computer is bad (PCM) I would try to find a used one that way it will be plug and play.

Please let us know what happens.
