Did you replace the cap and rotor recently?

No. Some further info: Vehicle is started and run about once a week. SInce replacing the battery cable and battery, the truck has turned over slowly even with correct voltage from the battery, but it does always turn over. Today it is turning at normal seeming speed, but not starting. 140K miles on truck.

OK, try the cap and rotor. I have seen MANY where that alone was the issue and if you have not changed it any time recently, it may be due or overdue. It may even be why it was turning slow if the spark was going down the wrong line.

Do you have a copy of the procedure for this? I haven't done a rotor before.

It is very simple, pull the wires off the cap, remove the 2 torx screws and remove the cap, then remove the 2 screws for the rotor and remove. The cylinder numbers are cast into the cap so you can easily line them up. Just be sure to make sure the screws are not over tightened.
