Okay...problem solved! Although there was power to the coil,by the battery there was a pair of wires that came out of the harness...and had a male and female plug that was badly corroded. So I cleaned the wires, cut out the connector and butt spliced the wires together. That must have fed power to the computer or something...because the truck runs like a scalded dog now.

I really appreciate the help! My $500 Pathfinder is now a $2,000 ride :o)
