Easy stuff. You have a burnt out glow plug. No big deal as long as you do not take it to a mug mechanic who tries to remove it cold and snap it of. Best to do it yourself, after reading about the process, the most important is the engine temperature, it must be as hot as possible even though it is uncomfortable to work on it is better than a snapped of plug. There is no need to panic you can drive the van as long as you like with a blown plug. Eric.
