IML: 90 imperial no start issue AGAIN!!

["M. Esposito" <cadmat@xxxxxxxxx>]

OK, this is becoming very frustrating.. but here's where I'm at. our 90 just wouldn't start anymore, turn the key, dash lights as it should ( goes thru a test to show all digital displays are working) and them as you turn the key, nothing happens, no click, no dimming of lights, etc.. so I asked here what it might be and it was suggested that the ignition switch was bad, when I took out the switch, and removed the lock cylinder, I discovered a tiny piece of the cylinder was broken off,  ( where the cylinder seats in the ignition switch ) anyway, I figured that had to be the problem because just for grunts and giggles I glued the tiny piece back in place, re-installed the cylinder and viola, the car started right up as it always had .. but only once, when I took it apart again, I cold see the little part had separated again, so a new cylinder was in order, and on order cause my local dealer didn't have them in stock, got it today, had the locksmith re key my old key
 to it, reinstalled it and again..NOTHING!! .. I'm back where I was before.. now this car does have the factory anti theft system with a starter interrupt, could that be the issue now? is there a way to override that interrupt to see if that's the issue? I have already had the starter tested and replaced the starter relay.. so now what?  can anyone please offer any suggestions?

Thanks, Matt
