Are there any good threads on oil pressure gauge. My oil pressure gauge doesn't work at all. I checked the ground on the condensor, and seems fine. All the other gauges work. The engine light does come on, but is always on. never goes off. tried to pull codes, but light wouldn't flash just stayed on. I read something on low voltage causing the light to stay on. Any help or directions to any existing threads you might know about. Thank you

 

Grab a maunal pressure gauge and plug it in at the sender, which is near the oil filter. Give the motor a few cranks, and see if it builds pressure. If it does, then the sender and or gauge is bad. You can purchase a decent one for $50 at an auto parts store.
