    i did change plugs and wires, checked all wires, and i dont think its the coil because if its in park i can push the gas pedal half way down and get it to red line, but if i put it to the floor it will sputter,

    Hi,have you check plugs & wires? you can check for bad wires by startig the car in a dark place , look for spark coming from the wires ,a bad coil can also cause misfire,Good Luck

Why when i poor gas in carb it runs and then a few mins later dies


Test the fuel pressure, if it's low or non existant, you have a bad fuel pump, fuel pump regulator, or clogged fuel filter. That car has a throttle body, not a carburetor. All fuel injected cars have throttle bodies

I have a 1990 chevy s 10 with a 4.3 engine it starts when cold will idle a few minutes then dies as a result of not getting fuel if I pour gas down the throttle body it will restart but only run l,ong...


Could be loosing power or pulse to the injectors. I would check for power and pulse ground at the injectors and see if you are loosing one or both.

Durango starts sometimes. then acts like its getting no gas and dies. if i stomp on gas it will keep running till i let off. bad gas ? fuel filter ? fuel pump?


I would suggest starting with the less expensive solutions first. If you pull the air intake hose off the throttle body and open the throttle with the engine off look down inside if it is black try spraying it out with throttle body cleaner make sure to spray it out good. Afterwards start it you may have to keep your foot on the gas for a few minutes to make sure it doesn't stall then take your foot off the gas pedal and see if it stays running if it does your throttle body just needed cleaned. Note do not use carb cleaner use throttle body cleaner only, carb cleaner can damage the sensor in your throttle body.

I have a 1995 chevy lumina 3.1 and upon starting the engine will either hesitate and die or it will idle and when i press the accelerator it hesitates and then the engine dies...what could this be?


you need a tune up...plugs, possible wires too, they might have a lot of carbon tracking deposits on them ...clean (IAC) sensor, if you"ve never cleaned it, believe me it"ll be dirty.. and then make sure you completely clean you throttle body too inside and out! but wait an hour after before starting to let it air dry...clean air filter or replace it, and replace fuel filter if it hasn"t been replace in a long time. also after you"ve done this purchase a can of Sea Foam fuel system cleaner $10 and pour 1/2 can into 1/2 tank of gas and drive around even if its running "a little rough", for about 30 minutes and this should clean out any fuel injectors that may be possibly clogged up! if you you cant drive the car but will idle only after cleaning (idle air control), pour some seafoam in the tank and let it idle for about ten minutes then try to see if it will run. If none of this works then you probably have a fuel pump not putting out the correct pressure!

Engine wont fire until fuel is poured in throttle body


1993 s-10 should have a 4.3 engine. Your symptoms tell me your throttle body injector is clogged, and only allows so much fuel to pass through it. Therefore, on a idle there is not enough fuel coming through to keep the engine running, or to start it. If you replace the throttle body injector your issue should cease.

I hope this information helps you, and I wish you luck on your repair.

Geo Metro 1994, diagnose no fuel presure problem.


Quite a few things can cause a car to die after idling for awhile, but if you have verified that the fuel pressure is actually dropping when the motor dies, the likely culprits are:
1) Electric fuel pump in the gas tank is bad
2) The fuel pressure regulator (on the throttle body) is bad
3) An electrical problem in the power to the fuel pump (like a bad fuel pump relay or lose ground wire to the relay's circuit)
