Oil pressure gauge reading
So my oil pressure gauge reads 60psi key ON engine not running. If I unplug the sender, gauge moves immediately to zero. I cold cranked the motor a few times to build up the oil pressure before I fire it up for the first time. After about a minute of cranking, it jumped suddenly and pegged the gauge. The sender is new, but my instinct tells me the pressure is good in the motor, but the sender is acting weird. Or this normal FD behaviour?

FD oil pressure senders are crap. They often get fouled with oil from leaky oil filter pedestals, but they usually fail low, not high. Try cleaning the connection. If that doesn't work, you probably need to replace it. Think I saw somebody selling a new one for like $70.

Anyone searching this forum many years from now who finds this thread trying to fix their problem:
Check the plug from the engine harness to the car harness behind the heater core. If you have a bad/loose connection, you get these symptoms. Fix the harness and problem goes away. |
