Problems that might *seem* like a relay needing to be reset actually indicate underlying issues:
* Blown fuse: Check the fuse for the fuel pump in the underhood fuse box. A blown fuse needs to be replaced, not "reset". Your owner's manual shows the fuse layout.
* Faulty relay: The relay itself might have failed. This requires replacing the relay, not resetting it. You can try swapping it with a relay of the same amperage rating from another circuit (if you're comfortable doing so) as a quick test to see if the relay is the problem. However, don't just swap with any relay; consult your owner's manual or a wiring diagram.
* Wiring problems: There could be a break or short in the wiring to the fuel pump or the relay itself. This requires tracing the wiring harness.
* Fuel pump issues: The fuel pump itself could be failing. This is the most expensive fix, requiring removal of the fuel tank to access the pump.
* Computer problems (PCM): Less likely, but a problem with the Powertrain Control Module (PCM) could also prevent the fuel pump from activating. This requires a diagnostic scan tool.
How to locate and potentially replace the relay:
1. Consult your owner's manual: It will show the location of the fuse box and may have a diagram showing the fuel pump relay location.
2. Locate the underhood fuse box: It's usually under the hood, near the battery.
3. Identify the fuel pump relay: It will likely be clearly labeled (but not always). A wiring diagram (available online or through a repair manual) may be necessary.
4. Visually inspect the relay: Look for any signs of damage.
5. Swap with a similar relay (carefully!): If you suspect the relay, cautiously try swapping it with a known good relay of the same amperage rating from another less critical circuit (after verifying it's safe to do so). If the problem moves, you've found the culprit.
6. Replace the relay or fuse: If the relay or fuse is faulty, replace it with a new one of the exact same rating.
Important Note: Working on the fuel system involves working with potentially explosive fuel. Always disconnect the negative battery terminal before starting any work. If you're not comfortable working on your vehicle's electrical system, it's best to take it to a qualified mechanic.
