Question about Ford F-150
Neither one of my fuel pumps sound like they are working when I turn over the key front nor back tank it won't start and I've changed the coil the fuel relay switch and several other things and its still not starting what else could it be I also forgot to mention I checked all my fuses too my inertia switch was popped PM I I pushed the red button down still nothing there is pressure in my fuel lines
First let's confirm that it is a fuel problem. Get a Coleman propane bottle and a torch that attaches to said bottle. Find a way to inject propane into the intake system. By filter or by maf sensor. As you inject propane into the system have someone start the truck. If it starts for 5 seconds or more then it is a fuel problem. If it does not start then it is a spark issue. Try this method and update me as to what happened and I'll try to help you get that truck going. Sorry only way to answer was to edit my post, it is quiet safe. Learned that in mechanics class in college. Safer than starting ng fluid. But i understand need your hesitation. Good luck

Fords have inertia fuel cut off switch. You need to check that first. If you dont have fuel. If you have fuel and no spark you need to check for inj pulse to injector. Make sure no fuses are blown. If no spark and no injector pulse then replace cranksensor.

I have a 1996 f150 and I had the same problem. I finally found out that the rear fuel pump is the main pump, and if it goes out then the front pump will not work either. There is a groud that both pump share on the rear cross member. If you are not getting good connection with the ground the fuel pumps will not work. Also if you replace the rear pump and it still does not work then your problem could be the fuel tank selector switch, it acts as a relay if it goes out then neither pump will work.
