I have recently replaced the fuel pump in my truck. I replaced the fuel pump relay at the same time. Now that I have everything back together, I have no power coming to the fuel pump/fuel level sending unit. I do have power to the fuel tank pressure sensor. Help please.

You replaced the relay-did you check the fuse-if okay could be the computer not grounding the relay to transfer power or wiring problem

I see this is a old post and whatever answer given now will be to late for the person asking the question. But for new seekers with that problem. Remove fuel pump/fuel level sending unit electrical connector from the old fuel pump module. Put it into the new one and see if that solve the problem.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
