Default Oil pressure guage pegged

I was replacing my ls1 manifold with an ls6, must of broke my oil pressure sensor because the guage reads all the way to the right (80+ I think). We bought a new sensor and when we went to put it in, the old sensor didn't appear to be broken. We replaced it anyway and the needle is still pegged all the way to the right? If I did break the sensor wouldn't it read 0? The only thing I can think of is that it is grounded somewhere. Anyone else have this problem? Any help would be great. Thanks

Haven't had that problem before, but try unpluging the sender, if it still peggs start looking at the wiring. Hope this helps.

Did you disconnect any ground wires? If so, double check them.

Yea might be it or alternatively try to sand the contact area somewhat and see if it improves.

Hmmmm, actually, if you haven't already pulled the manifold, you might not need to. Instead just disconnect the guage, check the connections from passenger side, re-install and re-check. If there are still traces of a problem, remove guage, replace with alternate one (if there is one), and re-check. This will tell you what it is exactly the guage or the wiring.

Pegged out sounds like a wire is shorted to ground. I'd start tracing wires....

Yeah if its pegged it means its "not plugged in" you might have pulled on the wire when pulling your intake out and broken the wire inside so it no longer makes a connection.
Get a multimeter to check the wires continuity from one end to the other.

I'd be willing to bet its in your wiring. I had the same **** happen to me its such a pain to pull the intake off so i was trying to avoid it but i eventually said screw it and i took it off again. Turns out the wire for the connector broke off inside the connector so i went to the dealer and bought another one for 20 bucks and that fixed the problem.
