Check to see if theres a big dent in your fuel tank, sometimes that will stop the pump, or it just needs replaced, before that though check your filters, there should be 2 of them

Check to make sure the fuel pump is working. If the fuel pump is not working check the fuel pump fuse and fuel pump relay, also check to make sure the inertia cut off switch hasn't been tripped. If the fuel pump is working then check the fuel pressure regulator.
fuel pump is overheating. it takes the 15 to 20 min. to cool down. Low fuel in tank? in tank fuel pumps use the fuel to keep them cool. what is fuel pressure at the rail? if fuel pressure is too low the pump may be working too hard and overheating. need to test for a bad fuel pump or clogged fuel filter or possibly an obstruction in the fuel delivery system.
Is the fuel pump working? i.e. if you (with a helper) disconnect fuel line nearest the fuel pump and turn on the key, does gas spray out? Beware that the fuel will spray out very fast as it is upwards of 18PSI or more. You can also get a fuel pressure gauge from an auto parts store and use that instead and not have fuel spraying all over the place. If the fuel pump is work, check the fuel filter(s). Some vehicles have more than one. If the pump is not working, do you have voltage at the pump itself? Fuel pump is usually controlled by a relay.
Try resetting fuel pump. I do believe the reset button is on the forward passengers side of vehicle. The button is behind the plastic shield. Reset once or twice. This hopefully will fix your problem. Look in your manual for exact placement of fuel pump reset button
If the fuel pump don't have power it means that, the fuel pump throttle is stuck. just go to a car mechanic and tell them that the fuel pump of your car don't work . if they ask say maybe the fuel pump throttle is stuck , so that the mechanic can do it fast.But if you want to work on it its the fuel pump throttle that you should work on because its stuck
first you need to test your wires going back yo the fuel pump inorder to see if you have a bad wire or not.. does the fuel pump initilize upon turn ignition on . if yes then you need to chk possible spark issuie . if no initilize then test connector at the fuel pump and work your way back to the fuel relay swtch and if that tests out work your way back to ignition switch . ( s/b only 1 relay )
You likely have a bad lift pump in the tank. You are working on the fuel pump on the fuel rail right? This vehicle has two fuel pumps one low pressure and one high pressure.
my idea, the pumps are working agianst each other. what is the line pressure supposed to be? I think the rear pump is burning the new pumps up. is the rear pump running when the front pump is running? Let me know [email protected]
