I have a 2008 350z Nismo. Car will crank and turn over, but die instantly. If you hold throttle down it will stay on for about 2-8 seconds, but will be stuck below 500rpm. Brand new plugs, checked them after trying to crank and were covered in oil. Previously on the way home from collage (2:30 drive) at about the 2:00 mark car was max coolant temp. Popped hood and had a crack in the top of radiator (stock rad) coolant leaked/evaporated out. Topped up with the coolant i had in the trunk. Car got to max temp (and i mean MAX) again and stayed there for the last 10-15 minutes home. Car was parked now fast forward 3 months later (without any driving) car won’t start, and has the issues stated above.
