1996 Pontiac Firebird Formula 5.7L.I know it will be hard to answer this question without looking at the car, but the service engine soon light came on and the diag code says it is P0117 (coolant sensor) and P1361 (ECM has detected no ignition control pulses; open or short circuit condition; failed ignition control module; ECM failure). Other than the light, which prevents me from getting a safety inspection sticker - I don't feel any problems with the car. Starts right up and doesnt miss or run bad. The temp gauge did move up yesterday (we just bought it yesterday). I changed the thermostat and that seems to have fixed the problem. I guess my question is, more likely the ignition control module is going out or is the ECM failing to read it? Thanks
have the same problem?
