Where is the Fuel reset switch on a 2001 dodge ram V8?

There's no single "fuel reset switch" on a 2001 Dodge Ram V8 (or most modern vehicles). Fuel delivery is controlled by the engine computer (PCM) and various sensors. If you're having fuel-related problems, it's not a simple switch reset. Instead, you'd need to troubleshoot the issue:

* Check the fuel pump relay: This is a common starting point for fuel delivery problems. It's usually found in the under-hood fuse box. You can swap it with another relay of the same amperage to test it.

* Check the fuel pump fuse: Also located in the under-hood fuse box. Look in your owner's manual for the correct fuse.

* Check for fuel pressure: This requires a fuel pressure gauge and some mechanical knowledge. Low fuel pressure indicates a problem with the pump, filter, or lines.

* Check for codes: Use an OBD-II scanner to read any diagnostic trouble codes (DTCs) stored in the PCM. These codes can point to the source of the fuel delivery problem.

* Check the fuel filter: A clogged filter restricts fuel flow.

If you're experiencing a problem with the fuel system, a qualified mechanic should diagnose the issue. Trying to randomly "reset" things without understanding the problem is unlikely to be helpful and could even damage your vehicle.
