A noisey fuel pump can be an indication of a worn pump. You have to do a fuel pressure test to determine if the pump is supplying proper pressure and volume

No voltage to fuel pump 2002 saburban


vehicles have a safty device that kills the fuel pump in case of a roll-over accident so the fuel will not be poured on to the car and ignite. also, this fuel pump kill switch is used when you are going to remove the fuel pump to de-pressurize the fuel line by cranking the engine while the fuel pump safety switch is off. you can restore the power back to the fuel pump by resetting the fuel pump safety (kill) switch. some are located in the trunk, by the fender well, behind the carpet. some are located inside the kick panel where the front passenger sits. check your motor manuel for that vehicle or ask a parts person at the dealership for the location of the safety switch for the fuel pump.

Wont idle or start without priming tbi


first check fuel pressure with a mechanical fuel gauge that attaches to fuel line schrader valve. around T.B.I. if no pressure with key on check fuel pump relay for correct operation, and also the oil pressure switch has the fuel circuit to it so possible oil pressure switch also. fuel pump has a check valve to keep fuel from going back to tank, so when u turn key on fuel pressure should go up within 1-2 seconds on gauge. if fuel pressure goes down quickly, possible bad fuel check valve, change fuel pump and fuel pump check valve (located right above fuel pump inside tank)

Truck will not start, has fire. relay ok. no trouble codes.


when you turn the key in 'on' position, do you hear the fuel pump hum? check under hood in black box,,fuses,,and relays. for bad fuse or fuel pump relay bad. try bumping fuel tank with something hard to see if fuel pump will engauge with key on. maybe bad pump. have you had off road? look for pulled plug from fuel pump underneath near gas tank.have you bent or damaged your igbition key somehow? the key sends a signal to your cars computer to engauge the pump and crankshaft sensor.but if you do have fire,,,it's a fuel problem, so you are on the right track. if nothing i've said helps, check for a bad fuel pressure regulator.hope this helps and thank you for choosing fixya.com!!

Re fuel gage.


the fuel tank sending unit is defective in your van, this has nothing to do with the fuel pump going out, this was a 100% incorrect statement by the shop that said this, but do understand that if you pull the fuel tank to repair the defective sender for the gas guage u might as well replace the fuel pump which also is in the fuel tank, they (the pump) are are getting worn out at about the miles you have on this car.

Unfortunately most likely your fuel pump is going out. Tahoes are notorious for the fuel pumps going bad. One word of advice spend the extra money on a GM fuel pump and don't go with aftermarket because the labor is quite expensive and if the new pump goes out in six months you are out all the labor again.
