I had a similar problem like that with my '89 Pathfinder. It was intermitently not starting. After being pissed off and dinkin' around with stuff. I found out that it was just a $25 (Dealership price) relay that was bad. It was the fuel pump relay. Since I replaced it I haven't had any problems. Too bad I replaced the distributor, cap, rotor, plugs, wires, and ignition coil before I found what was really wrong. About $800 spent for nothing, but at least I won't have to replace any of that for a while.
FORCED to own/drive a 93 Honda Accord - automatic (YUK!) for the time being. Nissan replacement on the way! FINALLY - as of 08/10/06 I'm back in the game! '95 G20t 5spd..blk/blk
