Fuel Pump Diagnosis And Repair Tips

Before diagnosing a fuel pump problem, rule out some other things first. Check the fuel quality and the condition of the fuel filter. Perform a pressure test on the fuel pump to see if it is operating to specifications. If the fuel pump is not working, tap the fuel tank with a rubber mallet to see if the pump starts working again. If the pump starts up or runs briefly, the pump motor is likely going bad.

Check any fuses on the circuit and the fuel pump relay. A blown fuse reveals potential wiring problems that should be diagnosed and repaired. Test for power and ground at the fuel pump connector to determine if there are wiring issues, including an open circuit. If you’ve ruled out all other problems, and the fuel pump is still not working, it will likely need replacing.

Why Does The Honda Odyssey Have Fuel Pump Problems?

In most cases, fuel pumps are designed to last the life of the vehicle. However, there are conditions where a fuel pump can fail prematurely. 

Contaminated fuel can damage or shorten the life of a fuel pump. Water in the fuel can also lead to corrosion of the fuel pump. Most fuel pumps have some plastic components, and the plastic parts of the pump can become brittle with age. Electrical issues like a corroded connector can also be the cause of fuel pump failure.

Be aware of potential signs of fuel pump failure, like excessive pump noise, hard starting, or rough running. Be sure to check out our post here for more tips on how to maximize the fuel pump’s lifespan, or download our Fuel Pump Troubleshooting Guide here.
