the vats system just disables the starter circuit, check the bulkhead connector, Gm had big problems with the wiring connctor that goes through the firewall. they corrode badly if moisture gets in there.

Next month is about right!

It will probably be next weekend before I get a chance to see her and the car again.

But I will look at the bulkhead and the relay center.

Thanks guys! I'll report back what I find.

Also, there would be an amber "Security" light blazing away on the dash.

Scrub the battery terminals, scrub the battery cables and bolts, scrub in-between the two positive battery cables, scrub everything. Use a wire brush.

Here'* the story guys. Mom took the car to local dealer in NE. They diagnosed as a combination of a bad neutral safety switch and bad battery. The battery was load tested again and failed. A leaking cell I was told. Hmm. Go figure. I just hope it'* fixed so I don't have to worry about her driving to and from NE to KS anymore.

Thanks for all your help guys!

sounds like you had a floater inside the battery shorting a cell at times. a reg. load tester wont pick it up unless its doing it right them, we have a small tester at work that checks the continuity of the plates and electrolite inside the battery. you just punch in the CCA and hit test. it will give you the voltage, the CCA left in the battery, and also tell you if its good,bad, good/recharge, or a shorted cell.
