Jesse, I looked back through your posts and I could not find what year
your van is and also if you are troubleshooting the digijet or digifant
system.  Let me know and I will try to assist.

Weird right? I know both relays are good and have swapped them out to be sure with known good relays. Makes NO difference.

I have done many engine builds/swaps and have never run into an issue like this. I really really want to fire up this new engine and get the van back on the road.
