1983 thru 2011 Rangers never had a fuel pressure sensor, for sure
They have an EVAP fuel tank "air" pressure sensor, in 1996 that can be in the engine bay, on driver side near the EVAP canister on rad support, so not on the engine
Fuel injected Rangers used a mechanical Fuel Pressure Regulator(FPR) thru 2011
On the engine 1986 to 1997, and in the gas tank 1998 to 2011
Just a spring and valve setup, no electrics
1996 Ranger
What engine?
2.3l, 3.0l or 4.0l
