Try leaving the gas cap off after the next time you fill her up. A car's gas tank has to vent when gas vapors expand in the tank. Usually there's a valve in the gas cap.

Conversely once you fill your car up, and then burns fuel, if it isn't able to **** a little air in, then it'll VACUUM LOCK. Kinda like when you have a straw in a Coke, then you put you finger over it, and lift it out? The Coke stays in the straw until you release your finger off it. In this analogy the Coke is the gasoline and the cup is your engine.

If the gas tank can't draw any air in, then it won't allow the fuel to flow.

This is the simplest thing I can think of to check. Other than that, it could be a problem with any of the fuel/air electronics.

My son left the dome light on all night. Replaced the battery. The truck starts but will not stay running. Ran perfect when I parked it.


The computer has lost its memory for idle control possibly.Try this, crank the truck and shut is off.Do this as many as 20 times , each time try to leave it running for 2 or 3 seconds so you can see if it will idle on its own.Do this till it relearns base idle.

Car will not start without pressing gas pedal to keep idle speed up. If I keep idle at 900 RPM or higher it runs as long as foot is on gas pedal. It then stalls out when I take foot off gas pedal. No...


Have the idle bypass valve checked, also called idle air control valve.
If that valve is stuck in the closed position, it's not allowing the fuel to bypass the throttle plate to keep it idling, resulting in stalling, but will keep engine running if the pedal is pushed down.

In park the engine dies; only will run if given gas


It sounds like there is a problem with the Idle Air Control (IAC) valve. Its job is to open and let air into the manifold when the throttle is closed at idle. If it does not open, the engine dies at idle. The IAC is mounted on the throttle body. Possibly the valve is clogged or stuck, in which case it could be ok again if it is removed and cleaned. Or it is broken, and needs to be replaced. Or, there is a problem with its electrical connection, that needs to be traced. Good luck, let me know if you have any questions.

Wont stay running


sometimes when you drain the gas or run low on gas the car is hard to start and keep running...if you can get it started let it run for awhile on its own to get the air out of the line and see how it does then

Try disconnecting the battery (both terminals and let set for a few hours) with ALL the accessorries on lights-heater-radio etc. This will draw all power from your system, then recconnect battery, it's worth a try even if it doesn't solve your problem. Bill
