Percy,

The Diesel heater you have was a factory option.
It's an Eberspacher DA-6. There is a shematic and
diagrams in the Bentley Repair Manual Page 82-12
thru 82-19   and 97-49 thru 97-52.

This has a troubleshooter page also if you have
trouble getting it too run.

They get gunked out from burning Diesel . I run
gasoline thru them to burn out the residue as
this heater will also run on gasoline.
Well it will even run on Kerosene.

I always do this safe and sane as the heater
smokes like a chimney when you burn out the crud.

If you have never used it before , it's very
simple to run- you just depress the on -off
switch which is a timer and turn to the right.
The farther right you turn produces more heat.

It's economical and effecient. It puts out about
22,000 BTU on high.

If you don't hear the pump  clicking (it has two)
, then you must check the safety switch which is
under the dash at the right of the steering
column.

The little red switch should be moved carefully.

If you hear.feel a small "twang" when you do
this, you should check the fuel pump fuse near
the fuse block. The manual shows the location.

If it will not run , it most likely is the
glow/spark plug, the combustion blower, the fuel
pump, or the thermostat. or just corroded or
loose or broken wires.

I stock most of these parts for the DA-6 and
BA-6.

Give it a whirl . There might be a metal cover
under your van that you can remove to access your
heater.

Check for rodent damage ( they like to build
nests in the exhaust pipe), leaking fuel lines
before turning on the heater.
