My '97 had a bad connector on the rollover valve (on the firewall) and it would cause mine to not start when it got warm. Once it cooled down, or got towed home, it wold start fine. Took me quite awhile to find that one. I cut the 2 wires going to the valve and tied them together , lots of tape and no problems. . That was after replacing fuel pump and relays, etc. I wasn't getting voltage to fuel pump.
