If you're having problems with your fuel pump, the issue is likely one of the following:
* Faulty Fuel Pump: The pump itself has failed. This requires replacement.
* Fuel Pump Relay: The electrical relay that switches the pump on and off might be bad. This is a relatively inexpensive part to replace.
* Wiring Issues: Worn or damaged wiring leading to the pump could interrupt power. This requires tracing and repair.
* Fuel Pump Fuse: A blown fuse will prevent the pump from running. Check your fuse box (usually under the hood) for a blown fuse related to the fuel system.
* Low Fuel Pressure: This could be due to a clogged fuel filter, a problem with the fuel injectors, or a leak in the fuel system.
What you should do if you suspect a fuel pump problem:
1. Check the obvious: Start with the easiest things: check the fuel level, ensure the fuel cap is securely fastened (a faulty cap can sometimes disrupt pressure), and check the fuel pump fuse.
2. Listen for the pump: Turn the ignition key to the "on" position (without starting the engine). You should hear a brief humming sound from the fuel pump area (usually near the fuel tank). If you don't hear it, that points to a relay, fuse, or pump issue.
3. Consult a repair manual: A repair manual specific to your year and model Silverado will provide detailed diagrams and troubleshooting steps.
4. Professional diagnosis: If you're not comfortable working on your vehicle's fuel system yourself, take it to a qualified mechanic for diagnosis and repair. Working with fuel systems can be dangerous if not handled properly.
In short, there's no reset; you need to diagnose the underlying problem causing the fuel pump to malfunction.
