Any warning lights stay on?

If you don't turn it off will it keep running till you do?

 

[2fast4u]

the service engine light blink on and of sometime thats it...

sounds like a fuel pump. clean your fuel filter first.

 

[2fast4u]

so fuel pump would stop it from cranking when it gets hot..

 

[FXjohn]

if you have to "pour gas" you have a fuel problem. if it;s cranking start by having autozone check you batt, cranking and charging system.

Sorry to ask so many questions.

Any ignition/ECM mods?

Where did you get the ignition module?

If the code in the flashing light is for the security system, it is shutting the fuel pump down, so it only cranks when you put fuel in the throttle.

i bought the ignition module at autozone someone said it might be a problem cause it was a aftermarket part dont know..i took the truck in and had the code checked they found no problem there.. 2 shops and they cant find whats wrong...
like to thank you guys for the help

 

[MrCritical]

Get the code checked.

Get an AC/Delco module.

 

[2fast4u]

they checked the codes no problems there but like you said it could be the module since it was an aftermarket....

thanks again for your help

This sounds a lot like a porblem that I just helped a friend figure out with a Chevy Tracker. You might want to check the throttle position sensor. If you have a manual it should show what to test for, you will need an ohm meter.

Just so you know if you have a 4 cyl it's the 2.5, if you have a 6 cyl it's either the 2.8 or 4.3.


Next time it won't start check for spark right away. Just pull off a boot and ground it on the manifold and look for spark. Also, check for fuel. Take off the air cleaner and look down the throttle body and see if any fuel is dumping out the injectors. You'll need a helper though.

This will narrow things down.
