Check engin ligyt at start up come on or not?
Ive been pulling my hoar out on this one. Electrical issues and wont start.
Does your check engin light flas when you place your the ignition on or when starting for a moment???
I put in a new ecm and it did that. strange stuff like the oarking lights and fuel pump constantly running. disonnected battery let it sit. now no power to fuel pump. did the cps check and its ok. replaced relay for FP. not sure if i got stuck with a bad ecm or not. something just aint right here.

Did you type this with your nose? Typo mess, jeez. The check engine light will stay on if the key is on/engine off. It will come on for a few seconds and then turn off if there are no codes when you first start the engine.
