Question about 2002 Chevrolet Silverado 1500HD

1 Answer

Truck won't idle when cold

When it's cold out my 02 1500HD starts but then wants to die and revs back up. If you give it a little gas and hold it for a few seconds it stops. An once you drive it and go to start it, does fine. I've changed the fuel filter and have ran 3 tanks of gas with lucas fuel injector cleaner. Any ideas what's causing it????

I had a similar problem with my 03 i went through the stages as you did. also i had a check engine light come on the read out was for lean fuel mix. I finally figured out it was the intake gasket leaking and when the motor got warm it expanded enough to close the leak. The way i tested that was when the motor was cold i started it and sprayed carb cleaner around the gasket and it almost died out. i'm not sure if that is recommended but that is what i did. I changed the gasket and have not had another problem.

Why won't my truck run?


check for vacuum leaks . Check for power valve operation . check for choke closing on acceleration. Check timing. Check for coil failing or condenser in distributor failing I would replace the condenser first as it will allow the engine to start but fails at revs.

1993 Chevy C1500 4.3L V6 TBI starts but dies at idle after warming up.


Low pressure from fuel pump, when the pump is cold the pressure increases, as it warms up the pressure drops (this happens in a pump that is going out) the normal pressure should be at 40 with the key on and engine not running, when started the pressure should stay around 36, any less it won't idle and may run as long as you hold the pedal down. The injectors are opened electronicaly, so as long as there is fuel flow the engine gets fuel to run.So check the fuel pump, soundslike you need a new one

I give it gas and it won't accelerate


Can be several problems, one the injectors can be clogged and not allowing the gas thru at a fat enough rate, two it could be a gas filter going bad.

Starts then dies immediatly


try giving a little gas when starting. If you get it to rev up and the only problem it dies with your foot off the gas then clean the throttle body. It may or may not help. Then replace the idle air control valve.
