All of the above and one more thing to check is the wiring to the starter itself. If it cranks over slowely, check the wiring, you'd be suprised how many miles a stock starter can last with a good battery and good wire contacts.
If it just isn't firing and the cranking is fine but no SES light, well, does the SES light even work? Too often previous 3rd gen owners will remove the bulb or let it burn out. You've got a 91 so it doesn't have a MAF (which is GOOD, I hate expensive finiky sensors) so if you bring the car to the next meet you can hook up my scanner and see if there are any dead sensors.
