If the pump is running and there is a good fuel pressure at the injectors, a reset button is unlikely to help - the inertia switch cuts the fuel pump in case of a collision and resetting it will only switch it back on. The switch is sometimes on display in the engine compartment but mostly hidden away and the location will be found in the vehicle handbook as the location is likely to change depending on territory.
If the pump is running and fuel is at the injectors it is clear the injector pulses are absent. That might be a sensor has failed or perhaps the immobiliser hasn't properly disarmed.
There is no fuel pump reset. If ou rainout of gas you may have ruined the fuel pump.
The only manufacturer that uses a resettable intertia switch is ford. This will only trip in the event of an accident to shut off the power pump.
Not aware of any re-set on Jeeps. But you said it won't crank? Starter is not working? Please clarify.
If it won't crank over from the starter, your problem is in the start circuit, and not affected by fuel pump operation. So, please reply.
Most Fords have a fuel reset button. When you ran out of gas you tripped the circuit. Most of the time the button will be on the passenger side by the kick panel. The exact location should be in your owners manual or your local library or auto parts store will have a copy of one for your specific vehicle.
the battery gets the starter running, the alternator recharges the battery and also takes care of the accessories. simple test for the alternator, test voltage without running engine, then test again with engine running, you should get 12 volts when off and 14 to 16 while running.
