Just because it is running , doesn't make it good. A fuel pressure test should be performed to get accuracy or, take a chance and replace the pump. Let ma know if you need instructions or diagrams to get this done.

    You need to find out how much pressure is getting there. You can check the fuel filter to make sure it's not plugged.

Most likely your fuel pump needs to be replaced. If, when you turn the key to the run position, you can't hear it humming for 3 to 5 seconds, it is likely burnt out. Best way is to take the fuel cap off, and have someone stand at the cap and listen. You will need to drop the fuel tank to replace the pump. ( PS: Never use starting fluid on a gas engine. For one thing, it can cause an explosion, and for another thing if it backfires you can blow your intake gaskets etc out)

Sounds like low fuel pressure.
A GM vortec engine needs at least 65 psi to start and run.

I have a 1992 chrysler lebaron about every 3 months it will start but wont tay runnig unless i have my foot on the gas and the tac barley registers I have done a tune up and changed the gas filter hel


As far as I know the only thing you are doing by holding the gas pedal down is bypassing the idle air control valve. The computer controls idle speed by that valve.
Most times the valve is faulty or there is dirt in the throttle body that blocks air flow to the valve.
If the check engine light comes on there should be a trouble code for the valve or the problem.

1987 mercrusier 180hp wont stay running unless i pump the gas


Could be a small amount of rust got into fuel filter from sitting empty, try changing fuel filter before worrying about the fuel pump.Filters could be partly plugged and its always smart to start with the cheaper fixes first.

CAN YOU HEAR THE FUEL PUMP RUN WHEN YOU TURN THE KEY?? if so then install a pressure guage and see if the pressure drops when you try to start the car, your problem is fuel , either a pump or no voltage getting to pump

Wont start unless i use starting fluid then wont stay running


with some one turning the key and some one at the fill tube where you put gas in. With your ear close to the fill tube the other person turn the key on you should hear a loud humm. If you dont hear the humm i would probally guess on it being the fuel pump in the tank. A another way to check to see is locate the fuel rail and on the fuel rail there is going to be a tire valve stem cap unscrew that turn the key on and see if there is pressure by pushing the center and see if there is pressure . Now there is gas in the line and if there is pressure it is going to come out pretty fast so be careful.So that is the two ways to check to see if you are getting fuel to the engine.

CAR WONT STAY RUNNIG


is it fuel injected? you might have a faulty sensor it sounds like a vapor lock, also you fuel injectors might be dirty or bad also check fuel pump pressure or a cloged fuel filter, or it is putting to much gas if your vette has a carb.

93 yukon wont stay running wont start unless u put gas in tbi?


Not sure of your question, but it sounds like a bad fuel pump or clogged fuel filter. If it stops running after gas in tbi is consumed, it is likely the fuel pump.
