Question about 1991 Oldsmobile Cutlass Calais
No fuel pressure when parked in garage in 03. 08 replaced sending unit and pump, drained tank, new fuel. Still no fuel pressure at throttle body. is there a wiring problem or selenoid issue? car has 250000 miles. has been parked since 2003.
Sounds sort of like a map sensor or the heating and cooling sensor. Both help regulate the fuel. also need to check to see if the thermastat is stuck to open. If the hot and cold sensor is giving a false reading of hot to the computer this can cause the car not to pump fuel. If the sensor is bad also replace the therm as well.
