Question
hi I have 300zx 90model auto twin turbo, it wont start it doesn't make a sound when turned with key but everything is working like fues, lights in dash, and acc lights come on. I think its the immobilizer bec the car did not come with the oringinal key we had to make one, so iam trying to find out how to disable the immobilizer or how to check if the car has one and were from, or how to fix it. And why it don't start.?? thanks wes.  

Answer
Wesley,

If the car is not making a sounds then it is the neutral safety switch since the immobilizer simply shuts off the fuel pump.  Bridge the starter with a length of wire from the small terminal to the big one and if the car starts it is the safety switch.
