We have just bought a van . The heater pump works but no heat. We looked under the van and a pipe that comes from the heater is dangling 6 ins . It drips went the pump is on. The fuel is not burning could it be blocked

If the fuel appears to be going in but not burning and something appears to be dripping out it could be the glow plug is not heating up. That's just an assumption. An internet search might turn something up. Best to either attempt to check it out yourself if you feel confident enough or take it to a dealer get it checked and serviced. Sorry, that's all I can offer.

If its dripping when the pump is on, it can only be fuel. You must have a blockage if that is the case. Can you get it out and have a look, its probably gonna have to come out anyway.
