If it was a stock rebuild the original PCM settings should be fine check all the fuses and wiring possibly something was damaged or left loose this stuff happens to the best of us.next the SES light needs to be reset with a scan tool make sure to record all codes stored in the computer as this will aid in diagnosing any problems. the car must be ran thru a drive cycle usually normal driving conditions of say a mix of city and highway driving until the PCM relearns all parameters like o2 sensors emissions sensors ect... this can also be checked with the scan tool in the readiness moniters these monitors will be reset every time the SES light is reset. when pumping the gas pedal 3 time you are just resetting the maintenance light.
