oil pressure
well i replaced my oil pressure sensor after it blew
anyhoo, the oil level is good, but when i first start it the oil pressure is at 75psi idle, it has never been that high. thought the oil was over full so i drained a little bit out to where its need a little bit added and i still have 75psi at idle.
it does no seem normal to me, and the pressure goes up to 80+ when i put it in gear and move it.
im out of ideas

i was thinkin that too, i might disconnect it and clean up the contacts, the old sending unit was leaking past the weaher-proof rubber seal out though the connector.
but it reads zero psi when i leave the key in run with the truck off, so im guessing it functions correctly?

Too much oil will not make the pressure go higher, it is a function of the pump and the bearings. A new pump will make more pressure than an old/worn pump. New bearings will show higher pressure than old/worn bearings. Cold oil will make higher pressure than hot oil. Does the pressure drop after you have driven the truck around for a while?
