You can try going to your local auto parts supply store and borrowing their diagnostic OBD code scanner. If there is a problem it will probably not be able to retrieve any codes. If you get codes then you will have a couple of places to start troubleshooting from. After my Chevy van stopped running completely, I pulled the ECM and inspected the greenboards for damage. Sure enough, mine had a burned out spot. I replaced the whole ECM for less than $300. It had to be reprogramed to my vehicle's specific VIN number and I had to retain the knock sensor and put it back on the ECM before I installed the new one. When you buy new parts ask questions. Sometimes the sexual intellectuals at the parts counter won't tell you important information unless you ask.
