  • Clear all DTCs from all module
  • Turn the Ignition On and the Engine OFF

How do I know if my fuel pump driver module is bad?

When your car fuel pump driver module is bad, its symptoms will manifest through engine performance. Some of the signs of a faulty fuel pump driver module include a smoky start-up, uneven running while idling, difficulty in starting the engine misses and hesitation when starting the engine, and power surges when you reverse.

If your car shows the following symptoms, then that is a sign of a failing fuel pump driver module.

Can I drive my car with a bad fuel pump module?

Yes, you can still drive your car with a bad fuel pump module. However, you will drive your car only for a short period. If the problem is not fixed on time, then your car will stall.

Most new car models are very sensitive and will stall almost immediately when the fuel pump module fails. So, if your car starts showing signs of a bad fuel pump module, take it to the mechanic immediately for a checkup and repair before it stalls.

What causes the fuel pump control module to go bad?

Multiple things can cause the fuel pump module to go bad. However, the most common cause of fuel pump module failure includes old age, fuel contaminants (bad gas, moisture, or dirt), and electrical faults.

Most fuel pump failures occur with little warning. So, ensure that your car fuel pump module is replaced immediately when it shows signs of failure.

How can I reset my fuel pump control module?

If your car has been involved in an accident, or if the fuel pump control module is tampered with, a warning may pop up on the dashboard indicating that you reset the fuel pump control module. If that is the case with your car, then below is a simple process on how to reset it.

  • Switch off the ignition
  • Inspect the fuel system for leaks, if there is a leak then fix it.
  • If there is no leak in the fuel system, open the access panel and push the reset button to reset the fuel pump module
  • Turn on the ignition to the ON position and let it stay there for a few seconds then return the ignition to the OFF position
