Try this, unplug the MAF meter and try to start the van, if it starts and runs you might need a meter. it's not throwing a code due to the fact that it hasn't run long enough yet. Also check the air inlet into the the filter box for restrictions, the little side vents on the passenger side are a great place for mice nests and what not. I do also agree with checking the exhaust for clogging as well. Try unplugging the MAF meter firstAgree, thus my question if it is possible that there is a code not readable by my OB reader, and if so would any garage full scope tool see such, or would it have to be a MB dealer specifically(proprietary codes??).
I am still hoping to solve it before resorting to the tow. In searching I found that Aqua Puttana posted some manual info in 2010 for a somewhat similar thing (no start condition). Vic, any chance you have some documentation on the sensors involved in startup/ and or troubleshooting for this kind of start, but shut down condition?
