To find the fuel pump relay itself, you'll need to consult your vehicle's repair manual or a reliable online source with wiring diagrams for your specific year and engine. The location varies slightly depending on options and trim level, but it's typically found within one of the under-hood fuse blocks or in a relay center near the battery.
Instead of looking for a reset, troubleshooting a fuel pump issue requires a different approach:
1. Check the fuses: Before diving into relays, ensure the appropriate fuses for the fuel pump circuit are not blown. Your owner's manual will show you the fuse box diagrams.
2. Locate the fuel pump relay: Use your repair manual or online resources to pinpoint the relay. It's often labeled, but you might need to cross-reference the relay's number to its function.
3. Test the relay: You can test the relay with a multimeter to see if it's functioning correctly. A simple swap with a known good relay of the same type is often easier.
4. Check for power at the fuel pump: If the relay seems fine, you'll need to check for power at the fuel pump itself. This requires some electrical knowledge and appropriate safety precautions.
5. Consult a professional: If you're not comfortable with electrical diagnostics, it's best to take your Tahoe to a qualified mechanic. Troubleshooting fuel pump issues incorrectly can be dangerous.
Remember safety first! Disconnect the negative battery terminal before working with any electrical components in your vehicle.
