I am working on 2005 f150 with 5.4l. No fuel at filter so I replaced the fuel pump. Still no fuel at filter, Checked plug at pump, power to pump but no ground at plug. Any ideas?

I have seen this a bunch of times, the usual culprit is the wiring harness under the driver's door next to the frame rail. If it catches a rock it damages the wiring inside the loom wrap. After a little moisture it corroded and loses the conductivity. Try that first, easy to repair if it is the problem. The wire is for the FPDM. Let me know.
