First,thanks to petrified.rabbit; i was testing for fuel pump voltage at the wrong wire.Did replace the fuel pump and ran the car for 4 miles.On the way back noticed the idle speed was low and rough.turned the car off and now it will not start.The scan shows dtc p016(map) sensor.Will this prevent the car from starting.Previous to this the car sat unused for 4 years and without a battery.Thanks
