If you didn't damage the fuel pump with the dry run, and the relays are new, and the wiring is connected properly, it should work. If you have checked all the fuses in the fuse panel and none are blown, I don't think the fuse would be anywhere else. I've got one idea you can try. It's a long shot, but I've seen it happen several times. The oil pressure sending unit or switch, is tied into the fuel pump wiring. If the oil pressure switch is bad, or the oil pressure is low, the fuel pump will be shut down. Disconnect the oil pressure switch and use a piece of wire or a sturdy paper clip and make a jumper wire. Plug the jumper into the end of the oil pressure switch wiring connector and try the ignition to see if the fuel pump works. If that doesn't work, I'll do some research on the fuse location. Good luck.

Fuel pressure regulator. It regulates the fuel pressure you receive going to the injectors. All the injectors would not be bad, so you have to take a step back to the next component, which should be the regulator.

Maybe you have a short in one of the wires at the fuel pump. If the pressure was low, it would probably stay low. There should be a bleeder that looks just like a tire valve. If not, remove the line at your filter and hook the gauge in there. It don't really matter where you put it, it should read the same anywhere. I guess if you wanted to spend the xtra time, ideally you could mount the gauge in the cab(run a "t" off of your fuel line) that way when it dies, you will see the gauge and be able to tell instantly.

Where is fuel relay


The fuel pump relay is only for the fuel pump priming when you turn on the key. After the vehicle starts the oil pressure switch takes over and runs the pump. If the pump is shutting off after the motor is running the oil pressure swith is probably bad. Let me know if i can help you further.

Check the fuse under the dash. Did you replace the inline fuel filter? If not, you could loosen the line going into the filter then turn the key to the on position. The pump should run for about 2 seconds then the relay should kick off. Turn off the key for approx. 5 seconds then cycle key back on and the pump should cycle again. If you get a 2 second burst of fuel each time then the pump is cycling. Install a new fuel filter and check the grounded wire by the tank. Hope this helps. :)
