This van was purchased with one other unit from Frito lay. Both trucks ran but there was only one ECU between the two of them. It has a cummins common rail 4 cylinder engine. Yes it ran fine with the ECU. The other truck was turned into a food truck and is gone, this one has been sitting a couple months while I decide what to do with it. We ended up taking a few parts off it - steering gear, a rear wheel, and I think one more thing.
