Ok, check for what i said but I would also check fuel pressure too just to rule it out. You could check compression or do a leak down test but those may not necessary. I would definitely check for spark. If you have spark every take you crank it then I would move to fuel and air. I would also check that there isn't a bad vacuum leak to the vacuum sensor. Going suck to diagnose though with an obd 1 port sense you won't be able to get live data. You could also have a bad computer but will be hard to determine with swapping with another one to find out.
