how to diagnose a bad fuel pump module on a 2007 f150

I changed camshaft positioning sensors and the VCT solinoids no change. They reset monitors was ok for very short time until both codes came back with vehicle stalling and running like crap. a shop replaced spark plugs and camshaft position sensors. Hi I have a 2004 F150 4x4 with a 5.4 triton engine that started off with a P0345 and a P0340. See the fuel pump circuit wiring diagram for testing reference in this link as well. See the steps to by-pass the drive module for testing reference in this link. See the fuel pump driver location on the frame rail in this link. See the driver module testing steps in this link. Let run these steps and we can work from there if needed.

The fuel pump driver module is located behind the fuel tank, on the frame rail. If the checks okay then proceed with the testing steps I have enclosed in the first link below. Before you start your testing, verify that you have key engine cranking power in and out of the fuel inertia switch. I have enclosed the testing steps to test it as well as bypass it to see if in fact, that is the case. Thank you for holding Ron, One very common cause for the fuel pump to not cycle on and run on your 2007 F 150 can be caused by a failing Fuel pump driver module and or in some cases the connection to it due to corrosion build up in the connector.
