What happens when you hit the starter on an electric fuel pump?
The switch will also let the pump run when you hit the starter because the engine doesn’t have oil pressure yet. One wire goes to the pump, one to the start circuit, and the other to the ignition circuit. So, when there is no oil pressure, the switch connects START to PUMP, and as soon as you start cranking it runs the pump.
Do you need the correct wire size for a fuel pump?
You must have the correct wire size to it. A relay is preferred. You may be getting the proper voltage to it, but not enough amps. Remember, the longer the run the more the power will drop. -Also, the grounding of it is critical. Many people will scrape the area where they mount it, or even add a ground wire.
How does a fuel pump work when there is no oil?
One wire goes to the pump, one to the start circuit, and the other to the ignition circuit. So, when there is no oil pressure, the switch connects START to PUMP, and as soon as you start cranking it runs the pump. When the oil pressure comes up, the switch connects IGN to PUMP, for normal running.
