The switch is attached to the brake pedal. Remove the wiring connector and the switch will either have a clip securing it or will be held in place with a plastic bushing. If a plastic bushing is used, a gentle pull will be needed to remove the switch. Install in reverse order and check brake light operation for switch operation/adjustment

could be fuel pump or even crank or cam , timing sensor. Did it start running strange before this?

You don't say if you have checked anything else. It could be any number of issues. I would look into either the crank sensor or the ECM as possible failures. Did you have any Service Engine Soon lights recently? Have you had the ECM checked for any stored trouble codes?

Does starter click? Try turning on headlamps and get someone to watch as you try to start car. If headlamps dim, likely bad starter or battery cable(s). If they don't dim, bad solenoid, starter switch, neutral safety switch. Try starting in neutral and jiggle shifter while trying. If it starts, replace neutral safety switch.

The PCM controls the ground to the injectors. Does the check engine light come on for a bulb check when the key is turned on? Check ECM fuses in underhood fuse/relay center. There is usually 2 10 amp fuses protecting the PCM circuitry.
