Replaced fuel pump ran for week now fuel pump runs continuously and wont start also changed crankshafts sensor Not getting and codes from computer
Have a pressure test done on the fuel manifold to check for fuel pressure regulator faulty and allowing the fuel to continually back to the tank and not having pressure in the manifold for the injector operation
SOURCE: cranks but won't start,new fuel pump,no power going to pump
look at inerata reset switch check for power at the switch
SOURCE: 98 expedition starts then after 15-20 seconds engine dies..
Replace the idle air control valve. Mine just did it today the 15th of August. I replace the Idle air control valve and problem solve. I have a 2000 Expedition 5.4 liter.

you should probably check your fuel pressure between the pump and the fuel bowl. my bet is that is is dropping pressure to zero causeing it to shut off just after it gets running. and there are several things that could cause that but the first to check is a return line valve on the side of the fuel bowl. that when pressure builds up it releases back into the tank and if it gets stuck open you will not have enough fuel pressure to run your truck. mine just did the same thing.

It is sometimes difficult to determine exactly what is wrong with the 7.3L engines. Many times it is hit and miss for the do-it-yourselfer. It sounds like you are getting enough fuel at first and then fuel is being constricted. You might want to try changing the fuel filter. Sometimes debris becomes lodged in the fuel tank switching valve which would require cleaning the valve or replacing it.
