VATS lockout - intermittent
I am getting internittent VATS lockouts. Eventually it starts, sometimes second try, I think I've had to wait up to 5 cycles before. I'll clean with MAF cleaner on a toothpick, sometimes that works sometimes it doesn't, so I'm guessing this is a true intermittent.
Any ideas where to start? I'll look at the FSM but it is tougher for intermittents.
Thanks for any help.

It cranks/runs about 90% of the time now I'd say. Usually will start after 2-3 lockout periods.

The problem is likely the wires in the ignition lock cylinder. Only way to know or to fix is to replace the ignition lock cylinder. Or you could just do the resistor method and bypass the ignition lock cylinder. That would solve the ignition lock cylinder.
Though there are other things involved as well as the starter enable relay. You can also bypass that too. Best method is to take the starter enable relay apart. Remove all the coiled wires inside. And then solder the plate thing that moves to the piece of metal it touches. Hard to explain, but I recall you want to permanently connect the outside two wires. Taking the starter enable relay apart and doing it that way means it's reversible.
Then, there is a 3rd VATS thing I believe that can only be turned off via a custom chip in the CPU. From what I recall as it's been like 15 years since I last messed with mine. I did all 3 bypasses. Ignition lock cylinder bypass, starter enable relay bypass, and turning off VATS in the chip on the CPU as I have a custom chip in mine.
