Hi all, i have a 2010 mustang v6, roughly 160k miles. I’ll note it has a variety of electrical issues like a short in the wiper motor harness, etc.

Recently it’s been intermittently stalling/sputtering during idle. It hasn’t inconvenienced me enough to look into it until the other day it died on me while driving and wouldn’t restart. I can crank it for minutes, but it refuses to turn over. I’ve scanned it and so far it’s not throwing any fuel related codes.

I don’t hear the fuel pump priming, so i started there. Checked the fuse for the fuel pump, checked the relay, all good. Swapped them with known working ones, still no change. I pulled the fuel line off the fuel pump and noticed it was bone dry, so assumed my issue is no fuel. Replaced the fuel pump. Still no change.

I hooked a multimeter to the wiring harness for the fuel pump and I’m getting voltage. Yet the fuel pump doesn’t even attempt to run. Bone dry.

Reset the inertia switch. No change. Replaced the inertia switch just in case. No change.

Any idea where to go from here?

You stated you have voltage to the fuel pump, do you have ground? It needs both to work. If there's voltage and ground at the pump you have a bad pump.
