2002 F150 4.6 Oil Pressure
I have a 2002 F150 with the 4.6 liter. Lately, my oil pressure gauge has not been reading any pressure when I first start it up in the morning. It goes to a normal reading after 30 or more seconds but it tends to bounce around and then stabilizes where it should be. Do I actually have an oil pump going out, a gauge problem or a sending unit problem?
