Where is the fuel pump reset switch located?

When set up for a couple of days,starts fine. Idle increases(between 1500-2000rpms). I turn engine off, then it wont restart.I changed numerous sensors: mass air flow sensor, idle position sensor, fuel pressure regulator, idle air position sensor. It does smell of gas but engine will not start (smells something like when it would be flooded).

Check engine light on?

yes
