So i have a 03 350z and I just replaced the stock pulleys with the unorodox underdrive pulley kit and changed my oil. Once i was finished i started the car the oil light was on and no oil pressure. But i checked the dipstick and oil is at normal level. and seems fine. so i then drove car and it was fine i drove for a couple hours and nothing happened still no oil pressure and light still on anyone know why this is happening.? hope to hear soon

 

So have you checked the oil pressure sensor?

 

sounds like ur oil pressure sensor isnt working dude

 

is there a chance you hit the oil pressure sensor as you where removing the oil filter? these sensor are quite delicate........
