Initially when the key is turned to "run", the oil pressure gauge (engine
not running at this time) jumps up, ~ 3/16ths of an inch.
Upon start up, engine now running, there is no movement on the oil pressure
gauge needle. After engine warms up, approx 4 minutes, the gauge indicates
~60 %, and remains there. The is no modulation from rev-ing the engine.
Question is, should I replaced the transducer, or the gauge, both appear
to be a very difficult task.
The problem is in a 1999 Ford Ranger XLT, V6, 4.0.
Would appreciate hearing from all parties experiencing like problems.
