I have a 1994 Jeep YJ that does not send enough power to the fuel pump; 4.72-5v. We have been able to confirm our fuel pump works, but there is something not sending the right amount of power to the pump.
One issue that has arisen since this has been the Fuel Level Gauge no longer works. Could this lead to the problem?
We checked EVERYTHING: Relays, plugs, followed wires, tested continuity from the fuel pump.
It's a huge headache and needs to work by Friday.
We have one suspect, a loose wire in the engine compartment. See images:
