Starting issues are normally related to ignition problems if you have good fuel pressure. Sounds like you are getting SHOT GUN tech support so far. The best thing to do is work towards getting the car to stage 0. When was the last time the car was tuned up? How old are the spark plug wires? Are your vacume lines in good condition? You're working with a 17 year old car, if all these things are very old you may have 3 or 4 small problems working against you.
