The service engine light always comes on when you turn the key on before you start it. You sure it doesnt go off when you actually start the car?

There might be a short to ground in the wire that leads to the A pin in the ALDL connector. That would put the car in diagnostic mode (engine off) or field service mode (engine running) and would cause the SES light to flash. Just a theory.</font>

Have you messed with the prom lately. That is what is causing mine to flash rapidly. Its in LIMP mode. Runs like crap.

Mine is stuck in limp mode as well. Waiting for new ECM to see if that cures it.
