If you're having fuel pump problems, the issue isn't a switch to reset. Here's a more likely breakdown of troubleshooting:
* Fuel Pump Relay: The PCM activates the fuel pump through a relay. This relay could be faulty and need replacing. This is a relatively easy and inexpensive fix. You'll need to locate the relay (usually in the underhood fuse box) and swap it with a known good one (or buy a new one).
* Fuel Pump Fuse: Check the fuse associated with the fuel pump in the fuse box. A blown fuse is another easily fixed problem.
* Inertia Switch: Some vehicles have an inertia switch that cuts power to the fuel pump in the event of a collision. This switch usually resets by pushing or turning it. It's often located under the dash or in the engine compartment. Look for a small, usually red, button or switch.
* PCM/ECM Problems: If the relay, fuse, and inertia switch are all good, the problem likely lies with the PCM itself. This is a more complex issue requiring diagnostic tools and likely professional repair.
* Low Fuel Level: While not a "reset," ensure you have enough gas in the tank. The low-fuel sensor can sometimes cause the pump to act erratically.
* Fuel Pump Failure: The fuel pump itself could be failing. This requires replacement, which is a more involved repair job.
To troubleshoot:
1. Check the fuses and relays: This is the easiest first step.
2. Check the inertia switch (if equipped).
3. Listen for the fuel pump: When you turn the ignition to "on" (not starting), you should hear a brief hum from the fuel pump. If you don't hear anything, the problem is likely in the electrical system leading to the pump.
4. Check fuel pressure (advanced): This requires a fuel pressure gauge and is best left to a mechanic unless you have experience. It directly measures the pump's output.
In short: Don't look for a "fuel pump switch" to reset. Instead, check the fuses, relay, and inertia switch. If those are fine, you'll need professional help to diagnose the problem further.
