My '89 ford crown vic, for the first time took longer then usual to start. It went about 200 feet then died and would not start. It's getting a spark and the compression on each cylinder is between 175-180 lbs. The fuel pressure to the injectors is 35 lbs. (within specs). The trouble codes are EGR valve pressure transducer/position sensor sonic voltage above closed limit, and coolant temperature sensor out of range, and intake air temperature sensor out of range. There is a pulsating voltage to the injectors when trying to start. the car as a 5 liter engine and 140,000 miles. Please help, thank you.
