i have a 96 camaro z28 stock. the problem im having on cold starts car takes to long to start it will turn over about 6-8 times before it starts. after running it starts right up car only does this when it sit over 1 hour can someone help me fix this problem.

 

Check fuel pressure.

 

did that change fuel pump an filter still same problem

 

Coil or ICM, I would say it's definately Ignition related.

 

ok how do u check them

 

it is def ignition related... this isnt a fuel issue...

1. checking coil- pull your coil wire off of the distributer and set it near a ground and see if the tip of your coil wire is sparking...if its not sparking(which it should be or your car wouldnt run) or if its erradic then your coil is going bad...if its sparking fine and isnt erradic then its fine....it should be crank spark, crank spark and not crank, crank spark, crank..it should be sparking consistantly with your crank...also do this test cold and warmed up

sounds like a coil problem to me though not an icm problem...if it was the icm it would either not start or start and die when it gets warmed up....when the icm is warm and getting old it will break down allowing it not to run....

so i really think its your coil..

 

ok i will check that thanks for the info
