Can you drive with a broken fuel pump?
As a seasoned auto repair expert at Kevin's Autos, I’ve encountered countless cases of fuel pump issues. A broken fuel pump can be a frustrating and potentially dangerous problem for drivers. In this article, I’ll explain what a fuel pump does, the risks of driving with a broken one, and what you should do if you suspect yours is failing.
What Does a Fuel Pump Do?
The fuel pump is a critical component of your vehicle's fuel system. Its primary job is to deliver fuel from the gas tank to the engine at the correct pressure. Without a functioning fuel pump, your engine may not receive the fuel it needs to run efficiently—or at all.
Can You Drive with a Broken Fuel Pump?
Technically, it might be possible to drive with a failing or partially broken fuel pump, but it is not advisable. Here’s why:
- Engine Performance Issues: A broken fuel pump can cause inconsistent fuel delivery, leading to engine misfires, stalling, or difficulty starting the car.
- Potential for Complete Breakdown: If the fuel pump fails entirely while driving, your car will stop running, which can be dangerous, especially on highways or in heavy traffic.
- Damage to Other Components: Driving with a failing fuel pump can strain other parts of your vehicle, such as the fuel injectors or engine, potentially leading to more costly repairs.
Signs of a Broken or Failing Fuel Pump
It’s essential to recognize the warning signs of a failing fuel pump so you can address the issue before it worsens. Look out for the following symptoms:
- Difficulty starting the car or prolonged cranking.
- Loss of power during acceleration or while driving uphill.
- Frequent engine stalling or sputtering.
- Unusual whining noise coming from the fuel tank.
- Decreased fuel efficiency.
What Should You Do If Your Fuel Pump Is Broken?
If you suspect your fuel pump is broken or failing, follow these steps:
- Stop Driving: Continuing to drive with a broken fuel pump can lead to further damage or leave you stranded.

How do you temporarily fix a fuel pump?
A temporary fix for a faulty fuel pump can be done by bypassing the fuel pump relay. To do this, locate the fuel pump relay in the vehicle's relay box and swap it with the same type. This will bypass the fuel pump's electrical circuit and allow the pump to operate.
Can a car still run with a bad fuel pump?
Your fuel pump is important for your car, and it would seem as if your vehicle couldn't move without one. That's not always true though. Some vehicles can limp along with a malfunctioning fuel pump for a few blocks or even miles.
