Yeah, The fuel pump can go bad . The normal warranty on the pump is 12 months or 12,000 miles. This is very rare . I would check if the fuel pump had a lifetime warranty.

I would also check the ignition switch, and all the fuses to make sure the fuel pump is the failure.

Good Luck

My fuel injectors are not spraying fuel. I have replaced fuel pump and fuel pump holder and fuses. Could it be a bad O2 sensor? I have a 1988 gmc s15 pickup truck.


SHOULD BE A FUSE FOR "INJ", THERE IS POWER TO ONE SIDE OF INJECTOR WITH KEY ON, THE COMPUTER GROUNDS THE OTHER SIDE TO OPEN INJECTOR. (THE COMPUTER DOES THIS IN MILLISECOND PULSES IF YOU GROUND ONE SIDE TO TEST INJECTOR IT WILL BURN UP INJECTOR, IF YOU HAVE NO POWER TO INJECTOR CHECK FOR CHIP IN KEY. USUALLY THE SECURITY LIGHT WILL BE FLASHING IF CHIP IS NOT READING. TINY WIRE AT KEY CYLINDER WILL BREAK FROM TURNING KEY.

How do I jump a fuel pump relay of a 1988 GMC K2500 with a 5.7L to get power to a sending unit from a 1998 GMC C1500 with a 5.0L V8?


Not sure that we are thinking of the same thing. The wires to the gas tank operate the fuel pump and the fuel gauge. The relay is used to send power to the pump and you should not have to do anything to it to get power down the wire to the pump. When you turn on the key, the relay closes and power goes to the in tank fuel pump.

No fuel and no spark


fuel pump , fuel pump relay on fire wall, fuel filter, may all need replaced, pump in tank, inspect all wiring in this circuit, especially all grounds,, grounds get overlooked & that is sometimes the problem. I have a 1988 gmc 2500, I 'm talking from experience. can you hear if fuel pump runs for 2 seconds, when you turn key on ? if not, ground problem or pump problem. relay has a fuse in it, check that. check all fuses. NOW, spark ! coil ? plug wires ? distributor cap & rotor ? replace them if you haven't !!!!!!!!!! get to work, see how you do ! good luck !

Why does my 1988 gmc truck turns off when driving


fuel pump, or fuel punp relay mounted on fire wall, check the fuse in relay, also check the ground wire from fuel pump (in tank) to the inlet pipe , under the truck, where you put gas in, fuel pump needs a good ground period. fuel pump could be on its last leg ! reason why I know this is cause I have a 1988 gmc 3/4 ton. to access fuel pump, I cut an access opening in truck bed, 12" square above tank at location of pump. better than dropping tank, besides the truck is how old ? makes a hard job easy. change your fuel filter also. good luck, ken
