Oil pressure - changed sender weird reading?
I changed out my oil pressure sender yesterday to a new Delco part. Fired up the engine and the gauge was pegged to the right, which, if correct would have meant I had massive oil pressure even at idle.
I replaced the sender because I was getting no reading previously (i.e. 0 oil pressure). However, I had diagnosed that problem as relating to damage from the intake install, the oil sender was twisted and broken.
I'm *fairly* confident that I'm getting oil pressure and that this is a gauge/sensor problem rather than a mechanical issue with the oil pump.
Anyone had this happen before - and any ideas on how to fix? I want to get a reliable oil pressure reading.

There isnt an accurate reading using a factory gauge. I replaced my sender with an Orielly piece and it reads low all the time. I verified actual oil pressure with a mechanical gauge so I dont even worry with the exact number that the dash shows.

I think this is right. Seems like open circuit is pegged to the right. If you short it I think it pegs to the left. I would inspect that wire closely and trace if back a bit. See if there is a break in it somewhere, got pinched or something.
