Yes. The pump must operate between a narrow window of pressure designed for a particular engine. Many times if the pressure drops only five pounds the engine will not start.

My 2000 bmw 328i won't stay running. i crank it up and about 3-4 sec later it shuts off can any give advice


Hi Vlad

This sounds like fuel pump problem, or maybe even a fuel blockage in the filter, as what might be happening is when you trun over the car a small amount of fuel is getting through and then running out quickly and not keeping it running, so either the fuel pump has an intermittent fault and only runs for a short time and stops, or your fuel filter may be blocked and needs replacing, to find out if your fuel pump is ok, turn the key so the lights come on on dash but dont run it, go to the rear of the car and listen to see if you can hear a humming noise, what might be better to do is get someone to be at the back to listen as you turn the key, or get someone to turn the key while you listen, if you hear the pump hum, then that will be ok and then you might have to change the fuel filter. this is what it could be, however there may be other things involved, but that would be a good place to start.

Hope that helps

I have a 1988 Oldsmoble cutlass supreme gt and it wont start unless i spray starter fluid in the carbuerator.


Sounds like you are not getting any gas to the carb. Turn the key one click with radio off but don't try to start the car and listen for a humming sound coming from the rear of the car (gas tank area). You are listening to hear for the fuel pump. If you don't hear any humming then either the fuel pump relay is shot (cheapest fix) or the fuel pump is shot.

Check your fuel pressure. When you turn the key to the accessorie point you should hear the fuel pump pressurize the system. If you can't hear it that could be your problem. If you can hear it I would then check the fuel relay..usually not far from the gas tank.

My 2002 yukon cranks but does not start on 1st trun of key but will on 2nd?


Turn the key on and listen for the fuel pump to run for about 2 seconds. If you don't hear it run the may be a problem with the fuel pump relay or its cicuit. The extra cranking from the first and second try builds up oil pressure and that will energize the pump through the oil pressure switch.

If the pump runs for the two seconds try to start it on the first key turn. If it still does not start there may be a pressure or deleivery issue. So many vehicles no longer have external servicable fuel filters, yours may not. If it does though you may want to change it.

Also, does a security light come one and saty on in the dash?

My car wont start i drove it to walmart to have my tires replaced drove it back home parked it went to go to the store and it wouldnt start so i tryed getting a battery thinking that could be it but it...


WHEN YOU TURN THE KEY ALL THE WAY ON (NOT TRYING TO START, BUT FOR ACCESSORIES)...DO YOU HEAR THE FUEL PUMP SWITCH ON? YOU HAVE TO LISTEN REALLY GOOD...AND MAKE SURE NOTHING ELSE IS TURNED ON
(RADIO ETC,.)) YOU MAY HAVE TO TURN THE KEY ON AND OFF SEVERAL TIMES TO HEAR IT!

IF YOU DON'T HEAR THE THE FUEL PUMP WHEN YOU TRUN THE KEY ON, THEN MOST LIKELY THAT IS YOUR PROBLEM!

IT'S A SHAME...THAT THINGS GO WRONG ...WHEN YOU ARE JUST TRYING TO DO
IMPROVEMENTS!

HOPE THIS HELPS!

I try to start it but it wont start it like there no gas going to it and i cant hear the fulp pump trun on and i dont know if it that


When you first turn on the key to "run" you should hear the fuel pump cycle by listening near the fuel cap. (Gas cap) If you don't next you need to see if you have voltage at the fuel pump harness.

Fuel is not reaching from the pump to the injectors on a 1991 S10


so the vech starts? you should be able to hear the pump running when you trun the key to the run postion. remove the gas cap place a peice of hose down the fill neck turn the key to the run postion , remeber the pump will only for 10 to 12 seconds, the pump will not run all the time until the vech starts. on the fire wall off this vech there is a 20amp fuse for the fuel pump the relay is there also . there is also red wire that has a female spade connection on it also. you can take a fused jump wire from the battery to this connection 20 amp fuse and power up the fuel pump. if the pump still dose not work warrntey the pump. good luck kdc744

Fuel pump


can I call you or you call me I can explain better
The ASD relay that supplies power to the uel pump only sullplies power to 2 seconds after you turn the key on then it truns off so you have to check for power immediately after you trun on the key you need two (2) people.
