91TT will start, Batterty charged tried dissconnect of theft mod still will not start, dead at ignition, any ideas? Are starters a problem, this is the second time this has happened. Car has only 31000 miles on it, is a classic, but not good if you can't trust it to start.

make sure the cam angle sensor(CAS) is plugged in tight.
mine will just not start when its warm and i have to wiggle the CAS plug on the drivers side.

So it's not cranking over? Any clicks or lights on the dash when you try to crank it over?

There is a starter solenoid in driver side fender well...you do not have to take wheel off. Google how to. They are like 22 dollars at parts store. Test ohms to see if yours is working if you don't think it will fix. But mine did the same.

Starter Relay Guide

Taking the wheel off makes it easier, but I suppose if you're a glutton for punishment you could leave it on.

Hey BigTDogg, it worked for me, this after a Nissan dealer said It was a dead battery,then bad starter and a host of other things, they never even checked the relay, took the car back, found relay, it was the original 20 years old never touched, replaced it and car runs great, thanks for your help.
