Oil Pressure gauge pegged to 100.
Installed electronic oil pressure gauge, as soon as i start the car, it reads 100psi (pegs the gauge out).
Wires were 12v, ground, and signal (direct to pressure sender)
What's happening? Is sender not grounding or something?

Re: Oil Pressure gauge pegged to 100. (packthis)
usually when the cars cold the oil pressure is 100+ psi.. as it warms up it drops ....
also i think the stock sending unit only reads on/off.. it has either oil pressure or not.. i dont think that it can acutally give a signal for different pressure..
not positvie but eh?

a stock oil pressure gauge never pegs the needle then drops.
he has a wiring problem. do not use the stock sender either becasue the stock oil pressure sender only reads if there is pressure above like 5psi, thats why there is only an idiot light and not a gauge

no i didnt mean it like that...
when the car is cold.. the oil is thick... its gonna have higher oil pressure.. as the car warms up the oil gets thinner so the oil pressure is lower.. **** my friend's car used to have 90 psi when it was cold.. then when it warmed up it would go to like 20-30 psi

100 psi is excessive pressure when cold. If nothing is crossed in your wiring, you may want to check your pump.

Re: Oil Pressure gauge pegged to 100. (Combustion Contraption)
i had a problem similar to this with my autometer gauge, except it would peg 100 with the engine off. When you open up the gauge there's a metal cap that encases the gauge internals and it had shifted and was grounding out the sensor wire, hence making it read 100. I took it off and it works great.
