* Engine cranks but won't start. If the fuel pump is not delivering fuel to the engine, it won't be able to start.
* Engine stalls while driving. If the fuel pump is failing, it may not be able to deliver enough fuel to the engine to keep it running. This can cause the engine to stall, especially under load or at high speeds.
* Loss of power. If the fuel pump is not delivering enough fuel to the engine, it will not be able to produce as much power as it should. This can cause the truck to feel sluggish and slow to accelerate.
* Check engine light comes on. If the fuel pump is not functioning properly, it may trigger the check engine light to come on.
If you are experiencing any of these symptoms, it is possible that your fuel pump is bad. You should have your truck diagnosed by a qualified mechanic to confirm the diagnosis.
