P0090 Code Fix

Got a Fuel Pressure Reg. Circuit fault code p0090. Messed around with it for a day and decided check the pressure regulator solenoid. Found the solenoid wasn't clicking or diverting air. Smacked it around with a hammer and it started clickinging again. Been driving it around since and no error code. It also seems to have better acceleration under mild acceleration.
 
I like any problem that can be fixed with a hammer.
I fixed my friends car with a rock once,.. he put the key in, turned it and nothing happened ,... I smacked the solenoid on top of the starter with a rock and we got it going.

i got that code paired with a p0171 where is that solenoid located?
