Could be a fuel pump although they normally only hum very briefly and change to a clicking sound that means they are maintaining fuel line pressure that was built up quickly when the ignition is turned on.
BTW; pumping the gas pedal is a good way to flood the engine; if the choke is still operational, pressing the pedal once to the floor and then releasing it should set the choke and enrich the air-fuel mix for starting. If the engine get flood, holding the gas pedal to the floor will help dry out the plugs so they can fire again.

My 2004 cavalier will not turn over without excessive pumping of the gas pedal. Battery, starter and everything else seems to be fine. Is it the pump or something else?


Try this next time you start it. Turn the key to the run position, do not start the engine. Wait 3-5 seconds and turn the key off. Turn the key right back to the on position and wait for 3-5 seconds. Turn the key off. Repeat the above one more time. Now try to start. If it starts right up you have a fuel supply problem. Either the fuel pump is bleeding off or the fuel pressure regulator is leaking. Pumping the pedal is doing nothing besides buying time for the fuel system to pressurize. Post an engine size and I'll help you locate the fuel pressure regulator. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

After a long trip in my 2001 325i, the engine suddenly would not start after a quick stop. It was turning over fine, but would not idel. My uncle, as mechanic (specializing in US makes) climbed under the...


While I agree that the fuel pump would be the most likely suspect for this car failing to restart, if it is the fuel pump, however, the fact that it started after tapping hard on the throttle would be pure coincidence.
I believe that all e46s have used drive-by-wire throttles. That is - there is no throttle cable between the gas pedal and the throttle. The gas pedal generates an electronic signal that tells the computer where your foot is, and the computer opens the throttle. You say that the car experienced a sudden stop. Did the engine get shut off while the throttle was open? If so, perhaps flooring the throttle caused the electronically controlled throttle to cycle and reset itself (just a theory).
Listen for the hum of the fuel pump when you turn the key to the On position, before you turn the key to the crank position. The hum should last only a second or so. The pump shuts off after the system is pressurized. If you don't hear that hum when the car fails to start (if this happens again), then you have a fuel pump problem.

1991 s-10 pu//////electric fuel pump not working,is it a blown fuse


i'll try to help. have you checked the fuses and the relays under the hood in the black fuse box? with the key in the on position, can you hear the fuel pump humming? you may have to turn the key on and off several times 15 seconds at a time. if all fuses are good and the fuel pump relays good, try with key on, tap on bottom of gas tank to see if the pump will start to hum. if pump does start to hum, you'll need to replace that pump soon. you may get a couple of starts out of it, but usually not very many. hope this helps and thank you for choosing fixya.com

I have a '96 cavalier that makes a humming noise in the gas tank within 5 seconds of starting. I have tried two fuel pumps but the noise is still there!!!


Your fuel pump is supposed to hum, when you turn the key it primes the system and it will hum. When the car is running the fuel pump is running and it will hum. If the noise is excessive then try a higher quality fuel pump, it may be less noisy. You will hear the fuel pump on a lot of vehicles tho when you are sitting at a stop light with your radio off and everything quiet in the car.

I started my 92' Geo Tracker and started down my drive way when it just cut off. Now it will not start back, it is getting fire to the distributor cap,is full of gas and wil turn over but not start! Please...


Is the fuel pump running? When you turn the key to the run position (the dash lights come on), you should hear a humming sound coming from the gas tank for a few seconds. Thats the fuel pump running to pressurize the system before starting. It's kind of hard to hear, so get a friend to sit in the car while you lay on the ground near the gas tank. Have them turn on the key and listen. No hum means the fuel pump isnt working.

My explorer ran out of gas, i filled it up to about a half a tank, now it just turns over but wont start


if it's fuel injected,look on the fuel rail for a schrader valve--looks just like a valve stem on a tire but shorter.remove cap,again just like on a tire.turn key to on-push valve stem in as if to let air out if you get air,then gasoline,you have just bled the system.replace cap,start car.if you get no gas,remove gas tank cap,turn on key,listen for ""hum'' of fuel tank.no hum,check fuel pump.modern[plastic] fuel pumps will self destruct if run dry,even for a short time.

99 gmc wont start


check electric fuel pump operation ( located in the fuel tank ). Occasionally a fuel pump will burn out when running out of fuel, due to the fact the pump runs DRY for about 30 seconds till the fuel stops flowing out of the injectors, the engine quits, simultainously losing oil pressure which FINALLY shuts off the fuel pump. Sometimes TOO LATE. Hope this helps

2002 Pontiac Montana, I ran out of gas. Put in about 6-7 gal. Now it will not start up. Please help.


TRY TURNING THE KEY ON AND OFF WHILE LISTENING TO THE HUM OF THE FUEL PUMP. THIS WILL CYCLE THE FUEL PUMP ON TO PRESSURIZE THE FUEL LINES. IF YOU DON'T HEAR THE FUEL PUMP KICKING ON THEM CHECK THE FUSE FOR IT, UNDER THE HOOD. HOPE THIS HELPS WITH YOUR DILEMMA. LET ME KNOW. BEST OF LUCK
