No, two separate circuits.
Clogged fuel filter, defective fuel pump, blown fuel pump fuse, defective fuel pump relay, or it is out of gas and you have a faulty fuel gauge.
A fuel pump relay switch can cause your car to stall after starting. A malfunctioning fuel pump relay switch can cause your car to not start at all.
I doubt it.
No.
It may possibly be the fuel pump has quit working......or the fuel pump relay. Have your fuel pressure read by using a gauge connected to the fuel rail. If the pump is NOT pumping then you have to find out if it's the pump or the relay. you might check the ignition coil.
Yes, along with many other causes a bad fuel pump relay can cause a no start. The fuel pump relay provides power to the fuel pump.
For the fuel gauge? In the gas tank on the fuel pump.
Yes, a defective relay will prevent the pump from running.
Yes; if your fuel pump relay fails you will not get fuel to your motor and your vehicle will not start.
There is no relay for the fuel gauge. It is powered directly off the ignition switch. The fuel pump relay is behind the driver in the engine compartment on the fire wall just forward of the air cleaner.
No, you installing a fuel pump has nothing to do with the fuel gauge
- fuel pump inertia switch " tripped " ( do you see a fuel reset light turned on in your gauge cluster ? ) - blown fuse for fuel pump / fuel pump relay - bad fuel pump relay - plugged fuel filter - bad fuel pump - wiring connection to fuel pump
