Fuel Pump Voltage 7v

Here is the problem. I have 12v at the battery, 12v going to the fuel pump relay at the harness, but only 7v at the fuel pump connector. What to do now? As far as I know, the pump does need to run off 12v correct? I can hear the relay come on and go off. What could be going on? Thanks for your help.

Bad ground? How did you measure the voltage? Did you find the hot wire and groun the other end of the DVOM or did you use the hot wire and the other wire. Maybe the other end of the terminal is rusted?

It is a three wire plug, and i tested the one to the left with the one in the middle and then got 7v, then i tested the one on the right with the one in the middle and got 7v. What is the DVOM?

Also no rust, where do the wires run? I mean are they under the carpet cause that is where they look like they are coming from.

Digital Volt Ohm Meter

No easy fix. You are going to have to trace it all the way to the point you have 12 V then.
