What were you doing before it happen nothin i went out side and started it to let it warm up and i went back out side it was dead and wouldnt start...i checked everthing looks like its plugged up and check the spark plugs and everthing and i pulled up the back seat and unplugged the fuel pump! and it will start but die as soon as i plug the fuel pump up and check engine light wont go off and it wont flash the codes to tell me whats wrong with it!!! i put the paper clip in and turn the key on and the light just stays lite up and dont flash....

Eat Rice Posted December 26, 2007 Author Share Posted December 26, 2007 i dont know i think is a wire touchin or a bad ground i got it to start up after i let it sit for about 2 hours and it ran fine warmed up and i took off down the road and about 10 mins after i left the check engine light came back on and it died i never hit boost or anything i drove like grandma and now it wont start again.....

IVhorsemenmotorsports Posted December 26, 2007 Share Posted December 26, 2007 hmm. good point. vacuum? what you mean vacuum? it is not carburated. It is puzzling and hard to diagnosis without being there. When you say it was dead, did you mean that the battery was completely dead? What year is the car and type? if you can, swap a good known ecu stock preferably and give it a crank. Make sure you have enough voltage in the battery. more info on what is going on when you try stuff, it will help me figure out what you got Link to comment Share on other sites More sharing options...
