But you didn't say that the security light stayed on after the failed attempt to start (it should take 3 tries to start position before it quits completely). I've had some strange one try failure with the VATS on my 98. I think it may be the starter switch not keeping or making contact for power to the VATS computer and causing a no try to start on first attempt.
I also have 138K miles and for a year the starter has been slightly off sounding when starting sometimes--thought it was my 5-6 year old MAXX battery from WallyWorld with 7 year warranty. Found out few weeks ago it didn't crank right for a split second a couple of starts over couple of days then the speed of crank was fine. One night it didn't do anything. Friend even applied power directly to starter terminal to bypass all the cables and nothing. Usually GM starters make it to 200K miles he said.
You could just have starter problem. Rebuilder said the oil on it sometimes gets inside and causes contact failures. Do you have oil hanging on oil pan bolts above the starter?
