* Blown fuse: Check your fuse box for a blown fuse related to the fuel pump.
* Relay failure: The fuel pump relay might be faulty.
* Fuel pump itself: The pump might have failed and needs replacing.
* Wiring issues: There could be a break or short in the wiring to the fuel pump.
* Inert switch: Some cars have an inertia switch that cuts power to the fuel pump in a collision. This switch might need to be reset (usually a small button). Check your owner's manual for its location (it's not a general "reset button," but more of a safety cutoff switch).
If your Lumina isn't starting, you need to troubleshoot these possibilities, not look for a nonexistent reset button. A qualified mechanic is recommended if you're not comfortable diagnosing electrical issues in your vehicle.
