P0508 Idle Air Control System Circuit Low

Question

rough idle then dies after having a new fuel pump put on

Answer 1

p0508 is for the idle air control valve 

I would clean the throttle body and idle air control valve, with throttle body cleaner 

p0522 is for the oil pressure sensor most likely the sensor is bad if you are using the correct oil weight and the oil if not more than 4k miles.
