intermittent cranking
 

1995 Camaro 3.4 v6. I am having an issue with my car sometimes turning over, and sometimes not. runs and drives great when it does start, but problem has gotten worse. I put a new ignition switch, a new neutral safety switch, with no difference at all. also the vats is bypassed, on the key, and the module. the only thing I can think of is a faulty anti theft relay. what are the symptoms of that? car has been perfect up till about a month ago. it started as ever so often, now it is almost every time I try to start it.

any help appreciated, thanks
