Rant, rant, rant -

Now *both* my Vans ('86 GL & '88 Westy) have flaky FI/ignition systems.

The symptom (when running) is the tach drops to zero and it's like the ignition
is turned off.  Sometimes this is brief, other times longer (seconds) and every
now and then it *stays off*.  When it stays off, turning the ignition switch
off and back on usually restarts it.

The other case, is where the the van has been off and you try to start it.
Just cranks, no spark (and no tach).  Repeated quick retrys usually result
in a start.  Recently on the '86, it wouldn't start at all.  The computer
had been sitting on a foam cushion where I left it last time I cleaned the
connector contacts - the van had been running perfect for weeks since the
cleaning.  A sharp rap on the computer box resulted in an immediate
start and it's been running perfectly since ..

Damn Bosh FI!

Some of the things I've done:
        cleaned grounds/contacts/connectors/relays
        checked inside of computer for obvious problems
        new hall effect sender
        coil swap

Seems it must be the brain box and/or it's connector or it's wiring harness.
But on both vans at the same time?

Sheesh ..
