Hi Mark - At this point I have assumed either something is killing the
coils or I have had bad workmanship from Bosch - other than the spare coil
(original) which was reinstalled between new Bosch coil 1 and 2 which
continued to work when pressed into service.

I will give your suggestion a try - however if it does not start the van
then what would you then deduce?  I guess verification can also be made by
checking resistance as per the Bentley - there are 2 tests for checking the
coil.
