How do I know if my Ford Explorer fuel pump is bad?

Signs of a Bad Fuel Pump in a Ford Explorer
If you suspect that your Ford Explorer’s fuel pump may be malfunctioning, there are several symptoms to look out for:
1. Difficulty Starting or Not Starting at All: A bad fuel pump can cause your vehicle to have trouble starting or not start at all. If your Explorer struggles to start or dies immediately after starting, it’s important to ensure you can hear the fuel pump turning on when you first turn the key to the ON position.
2. Long Cranking Times and Irregular Running: Long cranking times and the Explorer running irregularly are other potential symptoms of a failing fuel pump.
3. Loss of Engine Power or Stalling: A failing fuel pump may not create enough pressure in the fuel system, possibly causing a loss of engine power or preventing the car from starting. It may also cause the check engine light to come on. Driving with a failing fuel pump is not recommended, as it can lead to further issues.
4. Sputtering Engine: If your engine starts to sputter once you’ve hit the top speed on the highway, it could indicate that your engine is being starved of necessary fuel, potentially due to a failing fuel pump.
5. Unusual Engine Behavior: Are you experiencing strange engine behavior, sudden stalling, or difficulty starting your vehicle? If so, it’s possible that your fuel pump is to blame.
6. Testing the Fuel Pump: If you’re interested in testing the fuel pump, there are specific symptoms to look out for, such as the vehicle cranking but not starting, and the ignition coil pack creating and delivering spark to all spark plugs.
It’s important to note that running low or out of gas can damage a fuel pump and shorten its life, so it’s essential to be aware of the warning signs that indicate trouble with the fuel pump in your Ford Explorer.
If you notice any of these symptoms, it’s advisable to have your vehicle inspected by a qualified mechanic to diagnose and address the issue before it becomes a major problem.

Will a bad fuel pump still come on?

How do I know if I need a new fuel pump?

Noises, backfires, and sputtering engines indicate a fuel pump gone bad. Typically, electronic fuel pumps won’t make a noise unless they begin to fail.

How does a car act when the fuel pump is going out?

If your engine is sputtering or stalls in the middle of your drive, your fuel pump is likely the issue. The low pressure caused by a faulty fuel pump means that your engine isn’t getting the fuel and air mixture it needs to initiate combustion and power the car.
