get an aftermarket mechanical oil pressure gauge. stock is junk and works only for 3% of the people in this world lol. the only think you can trust for sure is mechanical guage.

sounds like a bad ground if your not seeing crap in your oil filter if you cut it open .. if you go with a mechanical oil guage like i have done use the plastic it comes with ive seen to many isses with them. do yourself a favor and go to the hardware store and pick up copper tubing or like i have earls makes nice braided lines for it they come in 3 and 6 foot lengths. but you dont have to worry about it breaking. if you plan on puttint it in the car, ive seen some screwed directoly onto the oil log coming off the block.
