Car starts up fine when cold but when it reaches operating temperature it turns off. If you try and turn it on again it just cranks but doesn't turn back on until the engine gets cold. What could be the possible issues? Now I replaced the Coolant Temp Sensor and the one next to it with new OEM from Z1. The car also smokes from the exhaust on start up. Car is on CT right now and I live in NJ. My buddy is looking the car over and was going to drive it to NJ last Saturday when it cut off on him when he filled it up with gas. Feel free to ask questions and I'll answer as soon as I can. Thanks! Car is a 1990 300ZX NA
