Autometer oil pressure gauge

69 camaro, switching to autometer sport comp gauges:
Having trouble with oil pressure gauge reading. My o.p. Gauge reads about 90 psi all the time. Key on engine off, pegs gauge, remove sender wire (from gauge), reads 0. Origional problem was, engine not grounded. Ohms at sender, 224, ground engine, 56 ohms at idle, 64 ohms at 1500rpm. Reconnect sender, ground engine, no change. Not a fresh engine, 90psi seems impossible. Ant ideas. I'm lost.

Ps electric gauge, not mechanical. Have switched to o.p. Sender.

Re: Autometer oil pressure gauge

Engine block needs ground. Yes, 90 PSI is way too much indicated, normally 40-45 PSI at 2500 rpm.
I would think OP gauge would use an OP sender and Autmeter gauge use Autometer sender.
