It might be worth a trip down to AutoZone and pickup a generic
transistorized ignition unit for your van.  When I had no spark, etc., in
January list members suggested I try swapping out the transistorized
ignition unit.  It solved the problem for about $38.  Yes, it was brand x
and not Bosch, but it has done the job so far.
