No Oil Pressure..

Friend bought a running 2000 Z28...

But the Oil Pressure gauge isn't doing anything... what do you all think is wrong... it has a 6.0 block and other stuff...

Oil pressure sensor probably broken. It's located behind the intake manifold. Shouldn't cost more than 40 bucks. Usually breaks when somebody removes the intake because a hose connected to the back of the intake wraps behing the oil pressure sensor and it can snap pretty easy.

My thread from some time ago may help a little.

Unplug it. Key on engine off should go extreme hi or lo. Or hook up a test light between both terminals on connector. If light illuminates and gage move like it should then replace sensor.

I have never heard of doing this... so you just unplug the OPS and it should move on the dash...
