truck is 81 and it was running before the changes it stopped a couple of weeks after

yes the parts were replaced before the truck is 81

maybe one of the wires wiggled loose . like one thatthat connects to the coil. thy to disconnect the coil, and check the wires to make sure they are all doing their jobs

'81 and up are a bit different from the earlier models I have experience with...

Here is a link to the wiring diagram for an '81. http://www.luvtruck.com/PDF/Series11.pdf

A common problem with the older trucks is the ignition switch, do you have a remote starter switch? Another problem on the older trucks is the fuse panel, a good cleaning and wire brushing makes a lot of difference for a lot of owners....

Hope this is some help. Good Luck...
