Four versions of the fuel pressure sensor exist, the V6 engines have one on the
Fuel Rail and one on the fuel feed pipe or
Fuel Tank, depending on the model year. The V8 models have one sensor, either on the fuel feed pipe or fuel tank. To replace, relieve fuel tank and system pressure, disconnect the battery, and locate the sensor. For V6 engines, remove engine covers and intake manifold to access the sensor on the fuel rail, or raise the vehicle for the sensor on the fuel line.
