I turn the key to the on position and the CEL goes on then off like normal.

Then i turn the motor on and its fine for a few seconds. Then CEL goes on like theres something wrong with a sensor or something.

Then i try to pull the code to see whats wrong so i can fix it, but it doesnt blink at all and just stays solid like theres no code at all.

anyone got any ideas???

BTW i dont think its a bad ecu because if it was the CEL would be on at all times, even when i have the car in the on position before cranking the motor. Mine is off before i even crank the motor.

 

For this type of problem, when the CEL turns on, pull over and leave the engine running while you jump the service connector.
