[W126 Coupe] SEC Starting Failure After a Massive Downpour

[Dick Spellman]

Well based on what you describe you do have a wiring harness issue.  It's
very likely that your ignition wire set is the problem and if you get no
start at all I'd be highly suspect of the coil to tower wire.  You might
start with replacing that wire with a known working one.

In any event, I'd lose the Platinum plugs that the local auto parts store
pushes, they are not recommended by MB.  I'd make sure the new original
equipment set are gapped properly.  The archives have lot's of info on the
Platinum +4 and the problems you will create for your self with those plugs
installed.

Just my 2 cents.
