You have two choices. Get the codes read so that we know where to start looking. Or buy parts and throw them on like you've been doing.

I'll check for codes tomorrow I can't remember the numbers just something about speed sensor failure. I only disconnected one battery due to the rain about to come down on me. I'll find out tomorrow when I plug my Genesis in

Sounds like a broken or chaffed wire to the VSS. Found a print on line that says for econoline only the PCM pins 33 and 58 go to the VSS. You could Ohm them out. I don't trust online prints but use them for reference. Hopefully someone will be along that has access to prints that can verify

Mark,
Your comment is a good reminder to all of us to get as much information as possible, then post on this site asking for comments and insight, then uncork the bazooka as Rich would say. We have probably all tried a different order of these steps, usually with less than satisfactory results.
