In this blog post, we’ll walk you through the steps of how to start a car with a bad fuel pump. We’ll also offer some tips on how to prevent your fuel pump from going out in the first place. So, if your car is acting up and you’re not sure what to do, keep reading. We’ve got you covered.

Can a Car Run Without a Working Fuel Pump?

A car can run without a working fuel pump, but it will not be able to generate enough power to run for an extended period. The fuel pump is responsible for delivering fuel to the engine, and without it, the engine will eventually run out of gas. Additionally, a faulty fuel pump car will likely experience reduced performance and fuel economy.

If your car is having trouble starting or staying running, it could be a sign that the fuel pump is not working properly. If you suspect your fuel pump is failing, take your car to a mechanic for diagnosis and repair.

Step by Step How to Start a Car With a Bad Fuel Pump

1. Park Your Car on Level Ground.

The first step is to park your car on level ground. This will ensure that the fuel in the tank is able to reach the engine without any issues. If your car is parked on an incline, the fuel may not be able to reach the engine, making it difficult to start the car.

2. Turn Off All Electrical Devices.

The next step is to turn off all of the electrical devices in your car. This includes the radio, the lights, and anything else that may be draining your battery. Once all of the devices are turned off, you can begin trying to start your car.

3. Turn Off the Engine.

If your car is running, turn off the engine before proceeding. This will help to prevent any further damage to the fuel pump. If the engine is not running, skip this step.

4. Check for Leaks in the Fuel System.

If you leak into the fuel system, it can cause the fuel pump to work harder and eventually fail. To check for leaks, look for fuel stains under the car’s ground. If you see any, it’s a good idea to have the system checked by a mechanic.

5. Remove the Fuel Pump Fuse.

Locate the fuse box in your car. It is usually located under the dash or in the glove box. Find the fuse for the fuel pump and remove it. This will disable the fuel pump and prevent it from running.

6. Remove the Fuel Pump Relay.

The fuel pump relay is usually located in the engine bay, near the battery. It will be labeled and have a diagram of the fuse layout nearby. Remove it and try starting the car again.

7. Reconnect the Fuel Pump Fuse.

Once you have verified that the fuel pump is bad, reconnect the fuse and take your car to a mechanic to have the fuel pump replaced. DO NOT attempt to start your car with a bad fuel pump, as this could cause serious damage to your engine.

8. Use a Fuel Pump Jump.

If you have a fuel pump jump, you can use it to start your car with a bad fuel pump. Simply connect the jump to your car’s battery and then to the fuel pump. This will give your fuel pump the boost it needs to start working again. If you don’t have a fuel pump jump, you can purchase one at your local auto store.

9. Replace the Fuel Pump.

If your car still won’t start, it’s likely that the fuel pump is completely shot and needs to be replaced. This is a pretty big job, so you’ll probably need to take your car to a mechanic. While the fuel pump is being replaced, you might as well have the mechanic check the rest of the fuel system for any other potential issues.

10. Try a Different Key.

If you have a spare key for your car, try starting the car with that key. Sometimes, the problem is with the key, not the fuel pump. For example, the key may be damaged, or the chip inside the key may be malfunction. If the spare key doesn’t work, then the problem is most likely with the fuel pump.

11. Start the Car.

Once you have replaced the fuel pump (or tried all of the other steps), you should be able to start your car without any issues. However, if your car still won’t start, you may have a bigger problem on your hands and need to consult a mechanic.

12. Call a tow truck.

If you’ve tried all of the above steps and your car still won’t start, it’s time to call a tow truck. A bad fuel pump will need to be replaced by a professional mechanic. To tow your car to the nearest service station, call a tow truck.

Attach the gauge to the fuel line and turn on the ignition. The gauge should read between 30 and 40 psi. If it doesn’t, then the fuel pump may not be working properly. Another way to test the fuel pump is to listen for it. Turn on the ignition and listen for a humming noise near the back of the car.

If you don’t hear anything, the fuel pump may not work. Finally, you can check for leaks in the fuel system. Start the car and let it run for a few minutes. Then turn it off and look for any leaks in the fuel lines. If you see any, then the fuel pump may not be working properly.
