03 Tahoe, idles down, shuts off, gas pedal ineffective. - Replaced fuel filter, - when cool, runs for about 1 min, then idles down and shuts off. tahoe has pink fluid leak (probably coolant, heard rumor if coolant got into fuel mix, vehicle shuts down??? Or just the fuel pump, but why start after sitting for a few minutes??? Any help would be appreciated. Thanks

    Thank-you, will try tomorrow when I get a ride to where it died. FYI... it will start right up and drive about 100' or so, then shut back down.

    Checked for Humm, vehicle started, ran across parking lot 100', then when stopped, idled down and shut off. Waited 2 mins, started, ran in reverse back to parking space. tried to get to idle for humm, would not idle. -- still thinking fuel pump?

Have someone listen at the gas cap for the fuel pump humm when you first start the motor and keep listening if it stops hummimg. The piump may wok when there is low pressure in line and stop after build up of pressure.

    If the hum exist, consider a blocked Catalytic converter. To check this disconnect exhaust infront Cat. and see what happens. Good luck.

  • joyellowhors Jan 22, 2010

    Just for the hell of it try the catalytic disconnect first( it will you cost nothing). You will have time, because you are going to buy the pump online ( because it cost way tomuch at the dealer and is a special order at the parts store,who buys it online) Also if you want to try one more thing before spending $300 plus, go to dealer and get replacement electrical plug from car to pump connection( outside of gas tank ,on top of gas tank $20) just splice it in.

his problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

thats what it sounds like, a bad or clogged up fuel filter. if it bogs down when giving it gas, or going up a hill. its probably the fuel filter not letting enough fuel to engine. that is why it stalls at a stop. if this helps but not fully. check or clean idle air control motor. this is what maintains proper idle of vehicle. have a good day !!

Ignition modules will cause this. As will coils. Have your new coil checked , just because it's new doesn't mean it's good. I have bought a lot of new, bad prts.

Try replacing the fuel filter first and the primary fuel filter screen in the fuel pump may be dirty also. As for the the one in the gas tank which is a part of the fuel pump, your just going to have to keep the gas tank half full and add some fuel injector cleaner to the gas tank for the next feet fill ups. As for the fuel filter along the frame rail on the drivers side, they have a life of 30,000 miles or 1 year and needs to be replaced within those recommended intervals. Good luck and hope this helps, Note: the gas is what keeps the fuel pump cool, so low fuel in the gad tank will have the fuel pump run hotter causing it to fail prematurely
