Your post states that you verified no spark at 5..how did you verify that condition?

I understand what you are saying; I researched the 'cylinder 5 misfire' issue at mbworld.org and benzworld.org before I ordered all the replacement parts that would be suspect for the condition. The failures seem to follow the pattern: 1. plugs, 2. plug 'wires' (the 3 wires and the 3 posts/boots under the coil) and 3. the coil itself. I only replaced the coil and post/boot related to cylinder 5.
As far as testing for spark, unplugged spark plug wire from cylinder #5's new spark plug, leaving that spark plug in place, and using old spark plug in wire with base grounded. No spark appeared. Reattached to new spark plug in cylinder #5 and then repeated the same test with cylinder 1 spark plug wire and got a spark.
Greatly appreciate the help.
