Service engine soon is on and the truck idles low when cranked.

Truck idles very low when you crank it and then it dies. If i mash the gas for anout a minute it will them idle but very low around .5 as it seems like it's going to die. after running for a while it fires right up with out any problems idles well and runs great, but when it's cold and has not ran fopr a while, it's back to missing when fired and idling very low and shutting down unless you push the gas.

Take the vehicle to an autoparts store and have them use a scan tool to retrieve the fault code(s) stored in the computer. Most stores offer this service at no charge. The codes will help identify the problem. Sounds like a faulty Idle Air Control (IAC) valve to me, but the codes will narrow the reason down. Hope this helped and best wishes.

1992 Chevy silverado will crank but run at a low idle..when I mash the gas it shuts off


There are a variety of problems that could cause that, but if you mash the accelerator and it dies, you may want to put a fuel pressure gauge on the fuel rail to measure your fuel pressure. Assuming you have the V8 350 in it, that engine can require upwards of 30psi at the rail, and even a few pounds less can cause it to stall. You may have a dying fuel pump or clogged filter. That's where I would start, hopefully this helps!

Is this engine equipped with an EGR valve? Might have carbon deposits blocking the passageway causing the stalling problem.

Car won't stay cranked after started


If the Service Engine Soon Light is on continuously there is a serious problem with one of the systems of your engine. Have it checked as soon as possible. Unfortunately, it could leave you stranded which will be very inconvenient.

I can't hear the fuel pump working when I try to start the car. The car turn over to crank just fine, but as soon as it cranks it shuts off, if it cranks at all. As soon as I mash the gas pedal it goes...


Check the fuel pump relay and if is good then more than likely the pump has failed on this 16 year old car and needs replacing. The relay is under the hood on the passenger side, front of the engine, rear of the headlight housing, mounted on the upper part of the fender well, in the relay block.
