How to Troubleshoot Ford F-150 Fuel Pump Problemsby Alibaster Smith
The fuel pump on a Ford F-150 sends fuel to the engine. However, the fuel pump will eventually wear out. Premature failure is often caused by the gas tank in the F-150 not being more than 1/2 full or running the engine on a mostly empty tank. If the fuel pickup is not fully submerged in gasoline, it can be especially hard on the fuel pump, causing it to burn out as it draws in air and gasoline, struggling to do its job. Before having the fuel pump replaced, troubleshoot the problem.
Check the fuse for the fuel pump. Remove the fuse cover panel by pulling up on the release lever for the cover under the steering wheel and pulling down on the fuse panel cover. Remove the fuse for the fuel pump. Use the diagram on the underside of the fuse panel cover to locate the fuse for the fuel pump. If the fuse is blown, replace it with a fuse of the same amperage.
Turn the ignition to the "II" position.
Listen for the fuel pump to prime. You should hear a slight humming sound while this happens. It will only last for a second or two and you have to listen very carefully. If the fuel pump does not prime and the fuel pump is getting power (the fuse for the pump is not blown), then the fuel pump is likely malfunctioning or it has failed. Have the pump replaced by a professional mechanic.
