99 ranger faulty oil gauge?
So on my 1999 Ford Ranger FX4 level 2 with 216,000 miles (cuz i know you guys like that info) Everytime I turn it on, the oil pressure gauge says nothing (needle at bottom) like no pressure. The instrument panel says CHECK GAUGE. I wait like 30 seconds to 1 min. then the gauge pops up to the middle (normal operating pressure?) It NEVER goes anywhere but the bottom or jumps to the middle, NOTHING in between. Does this mean my oil pump is going out? Or is it simply the sensor is going bad that reads oil pressure? Was wondering if you guys have seen a problem like this before. Truck runs great. super smooth. but if no oil gets to engine that'll be quite a problem. Oil level is perfect (recently changed too) transmissions fluid, all fluids are proper levels. Just the gauge is acting funny. Any advice is greatly appreciated!
