I got a 04 G35 and the car has been sitting for a while couple of years. So took the spark plugs out put some marvel mystery oil and hand crank the car alittle bit to let the oil go down and lube the internals. after that (I have a regular key that doesn't have a chip on the key) I crank the car to build oil pressure. i crank it for a good 5-10 sec and let go for a bit and repeated 4 or more times. but the oil light stays on. doesn't the oil light suppose to turn off after it build pressure when i crank the car? now I'm scared to turn the car on. could it be a bad oil pump?

 

As far as I know, the oil light goes off after the oil pump starts pumping and the car starts.

Does your key without the chip start the car? Why don't you start the car?

 

I thought the oil light goes off when the engine has enough oil pressure build up.
no my key without the chip doesn't start the car. I just got it to open the doors if i'm locked out. I was afraid it might break something inside if it didn't have enough oil pressure since the car has been sitting for a long time. I started the car and the oil light went away thank you

 

Check that the vehicles oil level is full / remove the existing oil filter and replace with the OEM (Nissan) oil filter ONLY / before replacing the oil filter...fill it with oil! / start the engine let idle for 10 seconds / shut down / start and let idle for 15 seconds...did the valve train noise dissipate? / YES? you're done / NO? / add top quality engine oil flush/thinner (e.g BG / JB products) run engine for 60 seconds / shut down / repeat for 120 seconds / shut down / repeat for 5 minutes / change filter (OEM) and oil (5w/30 ILSAC) / start engine and let idle...engine should immediately return to normal / NO? extensive diagnostics will be required...engine replacement may also be required.
