The fuel pump relay is one of the most important elements of a vehicle’s fuel system. It is the element of the fuel pump that provides power in order to build up pressure. While faint clicking is normal with a fuel pump relay, you’ll run into a problem if it’s constantly clicking.

This can eventually lead to your car not starting if this hasn’t already happened. There are generally two reasons a fuel pump relay is clicking:

  1. Faulty pump relay
  2. Engine issues

In this article:

We’ll go over these reasons in more details and how to go about fixing them.

Spotting the Signs

Ideally, if you’re able to catch the problem early on, you can fix it before you run into problems.

Having said this, it’s unlikely you won’t notice problems with your fuel pump relay as they’re hard to miss when starting to drive, especially if it’s constantly clicking. Along with clicking, there are other factors you should look out for.

If your engine starts to stall or you notice that the check engine light is on your dashboard, you may be starting to have issues.

If your car isn’t able to start at all and there is no noise coming from the fuel pump relay, this is almost always related to it being dodgy.
