04 F150 XL 4.2 no fuel going to engine
My F150 2007 4.2 is not getting fuel to the engine. I have changed my fuel pump, filters and the engine will not start. Also changed the purge sensor. Any advice out there??

if the truck has an inertia switch make sure its not tripped.
do you hear the fuel pump running when the key is cycled to run? it should run for 2 seconds then shut off.
if not, check the fuel pump fuse. if the fuse is good check for power to the fuse and relay.
if the relay is clicking when the key is cycled to run, check for power and grd at the fuel pump connector at the tank.

It seems that there is no power to the fuse box do you happen to know what is needed to fix that? I really appreciate your help

Start at the battery + post and work your way to the place where you have no power.
You may have to look at the connections going to the CJB (central junction box) under the left side of the dash. Was the windshield ever replaced on this vehicle? They have been known to leak right from the factory and sometimes after windshield replacement. Look for corrosion on the back of the CJB.
