I THINK the factory security system has one tied into it but I have no idea where it would be. Best I could tell ya would be somewhere between teh gas tank and the engine

The 300ZX doesn't have a factory fuel cutoff switch. Many Z owners install one though.

If you're having fuel delivery problems, tell us what the problem is and we'll help diagnose it. If you're not getting fuel, I'd suspect it's a faulty fuel pump control unit (which is a common problem).

make sure the relay is plugged in good (green relay behind the driver side kick panel. have to remove some screws and it's kinda a bitch bc the hood release cable and lever, but you don't have to take it all the way off if you have small hands). one time mine came unplugged some how...

easiest way to see if your having fuel delivery problems, get a bucket, take the hose going into your fuel filter off, point hose into bucket, turn key. see if fuel pumps out.

im having fuel delivery problem on 1990 NA 2+2, my z cranks but doesnt start, so i figured the fuel pump is bad, after running some test i found that the pump works, but it doesnt work when i connect it to the connector, the connector has power, i checked the relays and fuses. so i thought maybe its the cut off switch?? can you help??

The only fuel pump switch that I know of is in the ECU (pre OBDII and likely after). It can be turned off in active test with diagnostic tools like Nissan Datascan but that's not likely your problem.
