Is your compressor clutch clicking on and off when you hit the AC switch? You can hear this even without the engine running as long as the key is to the ON position.

I agree with Mr. Shiftright. I appraise 50-60 cars a week and experience about a 10-15% accuracy rate. Beyond the underbody inspection a paint meter is a must professionally or as a hobbyist. It has helped me save 10's of 1000's of dollars in losses on vehicles that I have taken in trade with undisclosed damage. I personally recommend the FenderSplendor FS 488. I have had 2 for over a year and they are inexpensive very accurate and easy to use.

Need more info: Was any work done when it stopped? Will the blower work but no air out of AC? (will it blow heat?). Which AC controls does your car have?

I bought a 86 300zx non-turbo 5sp in GA, dealer said he sold it to a good customer who drove it to FL and it quit,towed back to dealer and I bought it. It starts for about 1sec. and quits. Valdosta nissan said that it had a 84 ecm harness and it wouldn't work but it's obvious that the car ran with this harness. I can hear the fuel pump when I turn the key. I've swapped out dist, crank sens, cyl temp sens. fuel pump, fuel pres sens, w/used units, all with the same result, starts and quits. and ecm's too. i've wrenched on motors for years, what am I missing? It's driving me nuts! It's a beautiful car and i've had these z's for years. Oh please help me z gurus.

Well if indeed it has a cobbled up '84 harness in there, your problem could be anywhere in the harness. It sounds to me like some vital signal from a sensor to the ECM is getting lost or misinterpreted, doesn't it?
 
You may need a factory manual and a good diagnostic computer to figure this one out. Once modifications have been made, all bets are off. You may need to initiate the tedious process of checking voltages and signals at each ECM port.
