Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello and welcome! My name is ***** ***** I can assist you with your question. Because there is no communication with the on board computer, this needs to be addressed and fixed first before anything else is done. I would be willing to bet this is the only problem. If not, this needs to be diagnosed correctly, fixed and then you can move on to other things.
You need to start by checking all powers and grounds going into the PCM with the key on. From there, we can pull a wiring diagram and pinpoint the problem.
