Fuel Pump wire harness
I had a back yard mechnic trying to install a used fuel pump in my baby and he says he's stumped because the pump has a 4 wire output but the wire harness is only 3. I talked to Dodge and they saidl, it's correct and how it's supposed to be evidently 2 wires are grounds-the extra for the sensor or something. Anyhow he's got the gas tank reinstalled and the used pump is working- but has low pressure and won't keep the van idling. Could this be the wiring is not correct, bad pump or any other ideas? The filter is supposedly fine.
