The reason is the PCM (power control module) it is located on the drivers side right beside the battery. It's a computer piece that tells the injectors to allow fule or not allow. I had this problem and found a replacement at a salvage yard for 25 bucks. Two bolts hold it in and take about 2 minutes to replace.

Was it running fine and quit? Does it sound normal when cranking? Ecm and distributor were common problems, dont go buy parts because you think that be the problem some light diagnostic work will make an affordable fix for both you and your pocket book
