What powers the fuel pump?

The fuel pump relay is what turns on the fuel pump when you start your car and powers it down when you shut off the ignition. The engine control module (ECM) uses the fuel pump relay to control when the fuel pump is on. The fuel pump relay supplies electricity to power up and power down the fuel pump.

Why do we need electronic fuel pump control?

Electronic module control has revolutionised the modern engine fuel delivery system by enabling more precise fuel control, better reliability and lower NVH levels. This additional electronic control means diagnosing fuel delivery system faults require a blended approach of both mechanical and electrical checks to ensure accurate diagnosis.

How does a battery protection relay relay work?

Timers are triggered by various means to initiate function of the relay. The primary purpose of a battery protection relay may best be illustrated by an illuminated glove box. When the glove box door is opened, a spring-loaded switch plunger extends as the door moves away from the latch.

How are electrical relays used in the car?

Reliable Relays. Automotive electrical relays are used to keep the heat of the electric load away from more delicate parts, like small switches. A coil of fine copper wire is wound around a tiny iron core inside the relay. A magnetic field is generated by the coil, when energized, and the field attracts a thin metal lever suspended above the coil.

Where is the fuse box located on a Chevy tracker?

Where is the fuse on a fuel pump?

It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump. The fuel pump relay is usually controlled by the ignition or powertrain control module, and when switched on, will provide current to the fuel pump so that it may function.

Why does my fuel pump fuse keep blowing?

Fuses are over current protection devices which means that you either have a short to ground (possibly intermittent) somewhere in the circuit or enough added resistance in the circuit that the current drawn by the pump is enough to blow the fuse. Also Know, does a fuel pump have a fuse?
