Have you checked for stored codes?
Here's a link to the Ranger board's Technical Information sticky:

The 94 is EEC-IV. There's enough info there to bring you right up to speed with the system. You'll need a multimeter (VOM) to pull codes.
There's some very expert guys on the Ranger board that would be happy to help you through this problem.
