350 TPI, 117,000 miles on engine.
Starts fine most of the time, but once in awhile you turn the key, & nothing!
I found that if I moved steering wheel up & down, it would start.
What do you think? Transmission neutral switch? Ign switch?
Help!

 

Just a wild guess, but it could be one of the two wires that go to your vat system maybe broke, they run through the column to the switch.

 

could b. my 89gta went through 5 ign modules and would act the same way. another item was a bad battery. i thought my ecm was bad this last time and i had my ign mod fixed and thought great now #6 or my vats, cause i wiggled my igniton and started. turned out to b my starter noid when car got hot. its frustrating i know. i about had it til i got it sorta figured out and i had this car for 8yrs now.

 

Could be the ignition switch. This is mounted down about half way between the firewall and the steering wheel. It has a metal rod that comes from the tumbler that connects to it. Did that come loose somehow?

I would check your wires too. Maybe you have a broken wire or bad ground.
