Let me start by giving a little back story on this truck. Chassis - 1990 Motor - 1980 Trans - 1988 Cab - 1993 In doing the cab swap I actually took out all the wiring and swapped the ignition system over to a GM style ignition. I am running a icm from a 1975 impala and a standard 12V coil. Before I moved away for over a year I had the truck running and driving. When I left I put the truck into storage. I got back a few months ago and have been trying to get it running and am stumped. I have tested everything according to spec. Changed the ICM, the coil, and the signal generator, or pickup coil in the distributor and set it to spec as well. I am getting power to the coil but not getting any spark from the coil to the distributor. From what I know when the motor turns the distributor it sends a signal back to the coil and grounds it out to cause it to send a spark back to the distributor that then sends fire to each spark plug. Can anyone help me or tell if I am doing something wrong that maybe knows this setup? Sorry its so long.
