1994 3.8, 5spd - fuel injector electrical prob..

Car Has 94K miles on it and returning from a trip out of town started running rough at idle and drinking gas bad. Once i got home i troubleshooted it down to.......
#2 fuel injector is not pulsing when noid light is connected to injector harness. When connected the light just says lit and when connected to the injecter just dumps fuel into the cylinder causing the plug to foul and the car to smoke from the unburned gas(i connected noid light to #1 harness and it pulses like it should). I've read the codes and the only code showing is for a Cylinder 2 misfire. Any ideas what would cause that circuit not to pulse other than the computer going bad????

problem just appeared no problems before hand..

Thanks in advance

finally got around to troubleshooting and fixing car this weekend. The computer went bad somehow on the #2 injector driver signal. grabbed one from the junkyard put it in and back running fine.
