What is the Fuel Pump Relay all about?

Every time you turn on the ignition of your car, you activate the fuel pump relay. This device sends an electric current to the fuel pump. Upon receiving this current, the fuel pump sends gasoline to the engine and the car starts running. While the fuel pump is active as long as the car engine is running, the fuel pump relay works only at startup and when you turn off the ignition. As long as the car is running, the fuel pump runs on the power it receives from the oil pressure sending unit or any other such power source.

The fuel pump relay is also called the relay switch and its functions are similar to those of the automotive fuse. Controlled by the engine control module, the fuel pump relay controls the current sent to the fuel pump. This device is a black plastic component, set in a small box with a wiring harness attached to its underside. Its sprockets attach to the engine assembly. Depending on the make of the car, you will find the fuel pump relay under the hood or under the dashboard, near the steering wheel of the car.

Keep in mind:

  • Fuel relay pumps can oxidize or rust and need to be changed more frequently that the fuel pump.
  • Typically, the coil and contact points of the fuel pump relay show damage.

How it's done:

  • The vehicle hood is raised and supported
  • The defective fuel pump relay is removed
  • The new fuel pump relay is installed
  • The fuel pressure is tested and codes cleared with a scanner or gauge
  • The vehicle hood is closed and road tested for proper operation

Our recommendation:

The fuel pump of the car is an expensive device that functions well with the optimal amount of current. If it receives excessive power, the wiring system around the pump overheats, and the fuel pump could get damaged or fail completely. The fuel pump relay has a limited lifetime so you should have our expert mechanics check it every time your brakes are changed.

What common symptoms indicate you may need to replace the Fuel Pump Relay?

  • Engine cranks but does not start at all.
  • Engine functions irregularly and does not start right away
  • Car slows down without your braking
  • Car comes to a halt after running only for a short distance

How important is this service?

If the fuel pump relay does not work properly, it will not activate the fuel pump and you car will not start. Further, a malfunctioning fuel pump relay could conduct too much power to the fuel pump and cause damage to or ruin it completely. This is why we recommend that you keep the fuel pump relay in perfect working order at all times.

Infiniti I35 V6-3.5L - Pre-purchase Car Inspection - San Antonio, Texas
Isai's expert service gave me the confidence to know I was purchasing a quality used vehicle and the information to make an appropriate offer on the vehicle I was intending on purchasing. He spent a significant amount of extra time explaining to me every step along the way. In addition to a 150 point service inspection, he taught me tricks of the trade only a veteran of many years would have known to look for when purchasing a used car! On time, friendly, courteous, and called ahead of time to let me know exact arrival time. Not only do I highly recommend but will use myself in the future. Awesome neighborhood mechanic work by a true craftsman! Thankyou!

Gerron

Infiniti I35 V6-3.5L - Power Steering Pump - Portland, Oregon
After having some unfortunate work done on my car by another mechanic, Gerron was kind enough to sort it all out. He also had some difficult circumstances to work under but he handled the job effortlessly from what I could tell. I work on cars to a small degree (no where near Gerron's level of expertise) and I just wouldn't trust anyone else besides Gerron at this point. He is honest, straight-forward, and the friendliest mechanic I have ever worked with.
