There is no emergency shutoff for the fuel pump. It is controlled from the ECM. There is a fuel pump relay in the relay/fuse box under the hood. But if you have power to the pump, it is probably ok. Having had a 1999 Dakota I had a situation where I was having intermittent shutdowns when driving that became more and more frequent. Sometimes I could restart immediately, other times I had to wait from 10-30 minutes before I could get a restart. I assumed a faulty fuel pump and replaced it only to find that it did not solve my problem. I researched the issue and found that the Dakotas and Durangos have a tendency to have faulty crankshaft position sensors. It will mimic a fuel pump issue since when the ECM loses sensor input, it shuts off the fuel pump. Test the pump this way - in a quiet setting, turn the key to the ON position, but do not crank the engine. With the drivers door open listen for a 2-3 second humming sound from the rear of the truck. This is the fuel pump priming the system to get fuel rail pressure. What then happens is once you start cranking and the engine fires, the ECM turns the pump on full-time. If the crank sensor is bad, the ECM cannot see that the engine is turning over and does not generate spark or fuel injector pulses, so even the fuel pump prime works, if it worked won't start the engine. At least if you hear the prime, you'll know the pump is functioning.
Only Ford products have an inertia switch for the fuel pump. If your fuel pump is not working you would need to check the pump relay and fuse for power.
Check fuses, Relays usally never go out, but try a new one. If you do not here the fuel pump prime the system for a few seconds when you first turn the key to the on position. then it`s your fuel pump.
Plus Check emergency shut off switch, in your manual it will tell you how to reset the emergency shut off switch.
If all this fails to work, I would say that your fuel pump is bad.
Thanks for choosing FixYa and welcome to the site. If you are talking about the fuel pump, check your fuel pump fuse, relay, and reset if equipped. Make sure that the pump is getting power by testing the wires with a voltage meter. If it is not, you have an electrical issue in the wiring harness. If it is and all your fuses, relays work, change the fuel pump. If you have any questions, please let me know. Thanks for choosing FixYa and have a good day.
