A fuel pump is an important component of any vehicle that has an internal combustion engine, including the Nissan Navara. The fuel pump’s role is to deliver fuel from the fuel tank to the engine at the right pressure, but what happens if something goes wrong? Since the fuel pump is responsible for delivering fuel to the engine, a faulty or damaged fuel pump can significantly affect the performance of your Nissan Navara.
If you think you might be having problems with your fuel pump, it is important to get it checked out by a Nissan dealership which offers genuine servicing. If you are in the Perth area, the friendly team at Maddington Nissan can help you solve any fuel pump problems.
How to tell if you have a fuel pump problem
If you have a problem with your fuel pump, your Nissan Navara will likely have one of the following symptoms.
- Excessive whining noises coming from the fuel tank.
- It is difficult to start your Nissan Navara or it won’t start at all.
- Your engine splutters, especially at high speeds.
- The car stalls when its thermometer shows high temperatures.
- Your car has a loss of power when accelerating, especially in high-stress situations such as driving up a hill.
- You have to fill up your fuel tank a lot more regularly than usual.
How do you test a fuel pump relay?
One of the reasons a fuel pump might be having trouble doing its job could be that the fuel pump relay is faulty.
The fuel pump relay is what activates the fuel pump to supply fuel to the engine. When you start your ignition, the fuel pump provides an electric current to the fuel pump so that it can carry out its job.
If the fuel pump relay is dusty or damaged, its ability to activate the fuel pump will be compromised, and therefore your vehicle’s performance will be significantly impaired.
If you think you might have a problem with your fuel pump relay, you can take it into a Nissan dealership, or test it yourself.
Method 1: Swap your current fuel pump relay with a good one. If the problem is solved, your original fuel pump relay was faulty. If your problems persist, it is not the fuel pump relay’s fault.
Method 2: Use a relay tester and follow the instructions that come with it. Relay testers, or multimeters, measure the electric current of the relay to determine if it is working properly.
Resetting your Nissan Navara fuel pump
