Hey guys my 2003 Nissan 350z car has roughly around 98,000 miles and was running perfectly fine till today. My car overheated and sprayed coolant everywhere on the bottom passenger side. My car didn't want to start after I replaced the coolant. So I did some research and replaced my crankshaft sensor and then bam the car started up on the second try. We let it run for about 5 mins and the car didn't overheat. Although when I tried to turn it on after the successful start it just cranks like it did before. I think it might be the NATS but I have a spare key and it does the same thing. The fuel pump sounds fine and I checked the fuel module/relay amps and they are good too.
I think it might be the camshaft sensors now? Any help would be greatly appreciated.

Thank You.

 

Where did the coolant spray from? Might be unrelated, hard to tell. Not getting any trouble codes? The NATS problem is hard to diagnose if you think you have other problems. A spare key wouldn't help anyway if the NATS antenna is malfunctioning. Too bad you don't have UpRev or some other kind of tune...I had my NATS disabled so I don't have to deal with that crap.

 

uh, sounds like you blew the headgasket. Do a compression check on that passenger cylinder bank.

Also, check the oil, if its frothy, that means its got coolant in it, which also tells you blown headgasket, or possibly cracked block(Rare)


Good luck sir

 

Well I checked the oil and it was fine. There were no signs of coolant or water in it. The car has started up a few times but I haven't taken it out for a test drive just yet. I will take it to an Advance down the street to see what codes it's throwing out.
