Hello Im new. i have a 2003 Alero 3.4L V6. I have had this problem many times allready. i will go to start the car, she will turn and everything but start. all the lights come and and she turns over strong. i think it might be the fuel pump. any idea's?

 

Check for spark & fuel if no spark check crank sensor, & coil, no fuel check if u hear the f/pump starting to prime up, or go onto fuel/rail & press in shrader valve & have someone crank motor over & see if u have fuel coming out. Is it a crank no start or no crank no start?[img]smileys/smiley25.gif[/img]

 

its Crank no start

 

After the start attempt, is the security light flashing? If so, you have a passlock problem.


Let the car sit overnight. then, turn the key to the on position without going all the way to start. You should be able to hear the fuel pump in the tank run for a couple seconds.

 

How does it run once it eventually starts (assuming it does eventually start)?

thats just it. it only gave me problems once saturday and sunday. and both times i had allready started it and was away from the house.

 

oh and to answer you question CJ it runs fine when i get it started.

 

My first thought is fuel filter with fuel pump in close second (there's an "anti-drainback" valve in the pump).


Just thinking....

ok well its not starting the first time everytime but after the first time she start right up....any more ideas?

 

A dirty fuel filter can cause that problem as well as the fuel pump.
