Q: My car turns over but won't start, no power to the fuel pump or fuel injectors

asked by on

My car turns over but won't start. It has no power to the fuel pumps or the fuel injectors.

My car has 130000 miles.
My car has an automatic transmission.

It sounds like you may not have any power going to the fuel pump relay. The relay wires should have ground on two wires, power on one wire and switched power on another wire. To activate the fuel pump your ECU actually connects one of the ground wires to complete the circuit and send power to the fuel pump. If the wires all have power running through them, then it is likely you have a faulty relay. The wire coming from the fuel pump is the other ground wire. I would recommend having an expert from YourMechanic come to your location to diagnose your wiring as this can be very difficult and time consuming without the proper wiring diagram.
