While out wheeling my 87 22re the truck suddenly starting running awful, as if it were on 3 cylinders.

I limp the truck home and check a few things out, be performing a basic test of pulling plug wires while at idle I determined that the 3rd cylinder is not running.

I then replaced wires/cap/rotor to rule those out and toss in a new set of plugs even though the old ones looked great. Despite this the truck still is only running on 3 cylinders. The 3rd cylinder is sparking when you pull the wire off and it seems to be getting fuel as after pulling the new plug back out it was wet with fuel, and the top of the piston had some fuel on it. I also did a quick compression test which tested good

I am stumped!! The motor had about 5k on it since I rebuilt it, and the fuel injectors were rebuilt at that time by Rich at cruzinperformance
