run the codes on the car. That should be your first step in diagnosis. Go to the tech archive. All you need is a paper clip and if your car is before 89 a test light. You will run both key on engine off and key on engine running tests.
It could be a host of different issues . The computer will store any codes and tell you what is not functioning properly.
