The fuel in the fuel tank also cools the pump during operation. The pump could have heated up internally, causing it to fail. I would recommend checking the fuel pressure with a gauge and be sure the fuel system is pressurized and not low. A fuel pump can still run and be heard, but at the same time, it also may not provide enough critical pressure to the fuel rail and injectors.

2002 Sunfire with 2.2 ECOTEC Car acted like it ran out of gas. Would crank, run roughly a few seconds, then again acted like it ran out of gas. The next day and the next 3 days it has performed...

have the fuel pressure and volume tested with a gage.this sounds and acts like a fuel pump problem.check the fuel filter as well and replace anyways.when it won`t start but cranks can you hear the fuel pump running.listen at the fuel filler neck with the gas cap off.if you can`t listen under the car at the fuel tank you should hear it running/if not hit the gas tank and if the car starts then the pump needs should check to make sure you are getting spark at the spark plugs to eliminate an ignition problem but i think its fuel.

Wont start after it ran out of gas after I filled it with gas

Cycle the key several times to the run position and then back to the off position to try to bleed the air out it. Let it sit for about 30 seconds between cycles. How much fuel did you put in the tank. I would say that you need to put at least 2 gallons in it. You may need to change your fuel filter. When you ran it our of fuel you clould have picked up crud off the bottom of the tank and plugged the filter. You mave have damaged the fuel pump. Remove your gas cap and have a helper turn the key to the run position not start position. You should hear your pump buzzing. If you don't hear it I would suspect that something is wrong.

98 Sunfire 2.2L automatic 210,000km Starts and in a second stops, can do 20 starts and same thing. Pump can be heard loud and clear. Gas pedal to the floor or not it just won't keep running? Happened...

Try turning key to on (not start) 3 or 4 times first, ( to prime it more) then try start and see if it runs a little longer. If it's been sitting there is a chance gunk in tank has plugged up filter as well. Make sure you add some fresh gas, as well as some "Heet" to remove any moisture that may have collected as well in tank. If it continues to not start and run, you may need to have a fuel pressure test done to see if pressure is where it should be. Pump getting noisy is also a sign that it may be weak. If pressure is low, change filter first and try it. If no improvement, you'll need a new pump. You'll want a new filter on there if pump needs replacing anyway, so try changing it first, it just might do the trick.

Ran out of gas, put gas in it, changed fuel filter and I can hear the fuel pump kick on, but it still won,t start.

Possible that there is an AIR LOCK and so you will need to bleed off the air within for the fuel to flow into the pump. So remove the fuel line and allow fuel to flow or blow into the fuel tank.( must **** out the fuel )
once the fuel comes over the pump will hold on.
Next time make sure that the tank does not run dry.

Car ran out of gas, never started again.

Hello , If you run a fuel injected vehical out of fuel , then you may need to purge the system of air. Locate the schrader vale( looks like a bicycle tire valve ) on your fuel rail. Remove the plastic cap by un-threading it. Push the center of the valve down , watch your face and eyes! Wipe up any fuel , the cycle the key on and off a few times and make sure you hear the fuel pump. Re-press down the schrader valve and check for pressure. It should really shoot out not dribble. Make sure the car has fuel , cycle the key again( cycle means on off on off not turning to start) car should start if there is no air in lines. Thank you , Quinn

My 2004 Pontiac sunfire wont start the battery is fine but its just not getting gas

When you turn the switch to ON do you hear a sound for a couple of seconds ? you should hear a sound which is made by the fuel pump as soon as you turn the key. If you do not hear anything, you may need to replace the fuel pump. If you do hear the sound of the fuel pump, check your fuel filter .

Our Montana ran out of gas yesterday and when we put gas in we tried to jump it and it wouldn't start, so we had it towed home. What can we do?

First thing is to replace the fuel filter. Now use starter fluid sprayed into the intake to get it started.
