My 2000 GT 4.6L has no oil pressure at engine start according to the oil pressure gauge, however the engine sounds normal at start, and the gauge kicks in after a minute. Oil level is normal and I recently changed the oil. This is only happening in cold weather. Any suggestions???? I'm thinking the gauge is sticking. When I rev up the motor the gauge goes to normal, and after the engine warms up it remains normal.

 

I think there was some kind of problem with the senders. Im going to move this to the Parts Desk so Randy can help you out.

 

thats correct, 1999 up had issues wth the oil pressure sender.....a new one is aval for @$10.00
