did you check the fuel pressure? there is a sharder valve on the fuel rail to do this. i know you have to have a certain amount of pressure in order for it to run.i think on fuel injection its around 60 to 70 psi.and on throtle body is around 30 to50.psi. i also know if you run your truck low on fuel alot it will burn up the pump gas is what keeps pump cool. also you said you found a pluged filter witch over time will burn up the pump. hope this helps.

Most fuel injected vehicles have a relay that controls the fuel pump so after the ignition switch has been on for about 5 seconds and the engine is not running, the fuel pump automatically shuts off.
I don't know what your original problem was, but I think if the car runs normally, you have probably fixed your problem. If you don't have a manual, you can probably go to the library and take a look at a manual that covers your vehicle.

Should be on the passenger side kickplate below the glovebox and to the right. You may have to remove the plastic panel to access it or look for a small hole in it and feel around for the button

The best way to help find the problem, is to have a fuel pressure test done on it, that will tell if the fuel pump is weak, or the fuel pressure regulator is malfunctioning. If the pressure is low, the fuel pump is weak,
if it is high, the fuel regulator is at fault.
