just today my oil press light started to come on and off. its starts by fading slowly on about 2 min after i start car and drive . it will fade off for a few sec and then come back on. any idea what this can be? sensor plug is ok and i have oil in motor??

check if you got oil first. Does it stay on when you idle ? Mine used to do that same thing at idle because of a spun bearing, hence my user name now

no at idle its off. but when i drive it will fade on and off at random. i dont know. i recently switched oil to that quaker state Q synthetic stuff.. i dunno if that would have anything to do wit it but car drives fine and does have ful oil too. ?? i did accidentally let a good amount of water pour behind the motor today when it was raining but i doubt that could make it do what it is.. but now my reverse lights dont work either. ?? and the fuse is good.
also. the oil p sender is only supposed to have one wire right

install manual oil pressure gauge, verify oil pressure. as long as you have good oil pressure i would say the sending unit is bad. or you can take a gamble and replace the oil sending unit (17.00) and see if the oil light issue is solved.

+1, your oil pressure switch is bad. I had the same issue not too long ago.

it hasnt done it since that day now. i think i got the sensor wet somehow and that made it act up ./

Ya, someone correct me if im wrong but the oil sending unit is on the back of the engine and the connection may have got wet and then dried out. However, I suggest an oil pressure guage to everyone!!! I lost one engine that could have been saved if i had on.... Usually by the time the light comes on...its to late...
