Do this before you do anything else. If this is a 3300 (3.3L) engine, there is a common ground post beneath the air cleaner, under the crossover pipe. It loses contact on these older models. It is among other things, the ground for the ECM, and will stop the car cold. Take the four terminations, which ground a total of 8 wires, loose. Clean it all up, and buff the terminations with some sandpaper to get any corrosion off. Be sure when you're loosening and tightening the nut to use a backup wrench on the hex base of the post itself, or you'll behead the terminations of the ground wires. Snug it all down and you'll be back in business. Be sure to disconnect the battery before doing all this because you don't want to buy a new ECM. Bet this fixes your problem. Good luck.
