I had the same problem as you back in 98. It turns out that one of my battery
plates inside the case was cracked. It would start strongly sometimes, and
other times wouldn't even click. Or, once I got it started, it would want to
quit. I assume the bad battery was drawing so much from the alternator there
wasn't much voltage left to run the electronics.
Get your battery checked out by someone who can do a full test.
Another problem I had that duplicated your AIS issue was a bad O2 sensor
heater. It's supposed to read 7 ohms or something like that, and it read
open. But I don't think that's your problem, because of your starting issues.
Hope that helps,
Austin
