SOURCE: shuts off while driving. no fuel pressure. pcm fuse blows/ fuel pump relay inserted.

Sounds like the fuel pump is shorted.

SOURCE: 1993 Jeep Grand Cherokee Fuel Pump?

Between 100-140 thousand miles the fuel pumps go out on the 1993 cherokee. Its a fact. All parts are manufactured with the knowledge that it will last for a specific period of time then it dies. The relay switch was helpful for a brief while because there was still some juice in that pump, but now that it is gone it is gone.

If you don't see the fuse box under the dash in the driver leg area or beneath the radio check for a covered box under the hood. There should be a fuse spec guide on the lid of the box that tells you where specific wattage should go and for what purpose. But, your fuel pump problem will not be solved by a new fuse.

SOURCE: 97 gmc pickup, 5.7 eng, fuel pump not operating,

What you need to do is check you fuel pressure. Go to a local auto parts store and buy a fuel injection pressure tester. The pressure fitting is on the top of the motor its a 3/8 ish sized metal line and has a screw on fitting like a tire valve does. This line comes up from the back of the motor to the right of the distributor and goes down into the intake. Make sure to have a rag handy to catch the fuel seepage. After you connect the pressure tester turn the key on and off three times and read the gage you should have atleast 58 pounds of pressure. If you have 56 pounds it won't run because the fuel injectors are a poppit valve style and need atleast 58 pounds of pressure to operate.

SOURCE: 1997 Suburban, cranks, won't start. Removed fuel

The oil pressure gauge on the engine runs the fuel pump until the engine receives full oil PSI and shuts off. Upon that time the relay takes over for the fuel pump

My suburban has to be primed to start


There is a separate circuit and relay that primes the fuel system when you start the vehicle. If you sit in a silent location and turn the key to the ON position (without cranking), you should hear the fuel pump run for about 5-6 seconds. This is to bring the fuel pressure up in order to let the vehicle start. Then the normal pump circuit takes over. Sounds like your priming circuit is not working. I would try the relay first.

Car ran out of gas and has been hard to crank every since. I don't hear the fuel pump prime but I do hear the relay click. There is no gas expelled or pressure coming from schrader valve and also batt


the fuel pump is burnt out. the pump uses the fuel to cool itself. running low fuel the pump heats up and burns the plastic gears inside. thats why the fuse blew. need to take out gas tank to change pump.

Do you hear the fuel pump running on the prime cycle (when you turn on the key) (runs for 3 seconds) or when you have oil pressure?Have someone listen back by the tank for the wrrrrr.If you do have to change the fuel pump,make your life easy and just tilt up (lift) the pickup box from the drivers side to access the fuel pump.Takes 20 minutes to change it that way.

Fuel pump won't run unless engine is cranking, but won't start


Are you sure it's running when cranking? It should have come on when key turned on.
This is for camrys up to year '91. It may apply in your '95, also. Check the 7.5 amp ignition fuse and the 15 amp EFI fuse and the EFI main relay, all located in the fuse box next to your battery. There is also the circuit opening relay tied in to fuel pump operation. It is usually found under center of dash. It is usually not the problem, but it is part of the checks for fuel pump operation.
If your car has a " check connector" or "service connector" (also called a fuel pump check connector) under hood on driver's side near the firewall (a little 1 inch cube with a cap on it), then bridge terminals +B and Fp with a jumper wire. Turn key to on (don't start car). The pump should come on. Listen for fuel return noise from the fuel pressure regulator, and verify pressure in hose from the fuel filter. If nothing, check those fuses above. Here is how power runs to pump: Battery to 40 amp main fusible link-to 15 amp EFI fuse-to EFI main relay-to circuit opening relay-to fuel pump-to ground. Ignition switch and the computer (ECU) work the relays to pass power to pump. Hope this helps some, Randy. Good luck.

No fuel up to injecter pump truck just stalled


Did you check for fuel pressure on the line from the tank while you had the filter off? Do you hear your fuel pump prime when you turn the ignition on? First I would listen for the hum of the fuel pump when you turn the key to the run position (not starting the engine) May have to get a helper and listen at the gas filler neck with the cap off. If you dont hear your fuel pump, check your fuses and relays. If the relay clicks when your helper turns the key on ( put your finger on the relay and ear down close to feel/hear the relay actuate)., and fuse is good, yet you do not hear the pump prime, I would say your fuel pump is shot.

If it is a diesel,check for fuel pressure coming off the direct drive pump hose while cranking the motor.

1997 Suburban, cranks, won't start. Removed fuel pump and it runs when attached to battery on bench. Power at all fuses, no power on grey wire at 4 prong connector above rear axle. Is there a fuel pump cut...

1996 GMC Suburban - Quit Running While Driving, Will Not Start


Listen at the back by the fuel tank for a 1 to 2 second prime cycle whirr from the tank when turning the key to run position after it has been off for at least 10 seconds.
No noise means no running pump.
....and no noise means.....
Most likely it will need a new fuel pump....80%
Fuel pump relay 10%
Fuse or bad wiring 10%

The quick fix to get home is to crank the truck to create oil pressure to fire the pump......and while cranking WHACK the tank hard with a 2by4 or something like that....to jar the pump..... and it may start running long enough to get it somewhere to be repaired.
This works 60% of the time on a dead pump.

If you do hear a whirrr.....you most likely need a ignition module or crank or dist pickup.

Car trys to crank but want


How about the fuel pump relay? or possibly the ASD relay. need to make sure you are getting voltage to the fuel pump when the key is on, the pump will run only for a few seconds when you turn the key to start to prime the system. If you dont hear the pump prime, check the aforementioned relays and associated fuses.

Fuse location for 2004 suburban


If it has blown, then chances are the pumps shot. Same thing happened on my 01 Tahoe.

Fuse is in the box on the drive fender. I believe it was a 10, 15, maybe 20 (as I recall, it was yellow). I don't remember the marking, but it didn't say fuel pump. Maybe something like APRS1 and APRS2. Something like that.
