So when I turn the key to the on position my op gauge pegs to the right and even when I start and run the engine it never comes down from the 80 psi range (pegged). the low oil pressure audible alarm goes off before I start the engine as it should and goes off as soon as I start the engine on a 2005 stingray 185 lx. I have foudn tow sensors coming from the a nipple on the block. One has a black wire held on by a spade clip and the other is a blue wire help on by a nut. one is op switch and other is sending unit. when I test the gauge I get continuity so I think its the sender. Is that logical? any other ideas to test? Thanks.

Sounds like the sender, just take the blue wire off the sender and see if the gauge drops back down to 0.
If it does, replace the sender.
