Hey Friends; I'm helping a young couple with a problem.Their 95 S10 4.3 has been getting harder and harder to start and now it won't start at all.Well I checked the fire,it looked fine.Pulled the air cleaner lid and no injector pulse.I made a relay jumper for the fuel pump that was replaced a year ago and it's humming right along.I pulled the 4 wire plug from the ignition module and powered up the IC hi reference wire (purple/white) to the computer with a testlight connected to the battery positive post and NO PULSE.I checked the four wires from the module to the PCM and the purple/white was open so I ran a jumper to both ends and when I power that wire with a test light now (purple/white),the injectors will pulse with a fuel spray but still NO PULSE while cranking.That lead me to believe the problem was in the distributor.I tested the module and it showed to be fine but I put on a new one anyway,still NO PULSE.I pulled the distributor out and replaced the pickup coil and it didn't look very healthy at all.I examined the reluctor wheel as best I could.It looks fine to me.The shaft isn't loose in the distributor and the gear looks normal.I tested the distributor with my module tester attached and the reference light flashed up there as bright as the tach light on the tester. I was sure the pickup coil must be the culprit.Well I went to their home tonight and dropped in the distributor and dog-gone-it, NO PULSE.What am I overlooking here.Would someone "PLEASE HELP ME".Thanks R.D.
