Not that weak spark didn't cross my mind. But when watching the plug fire I can't say that the spark looks any different than any I've seen before. But given that.
1.) I don't have any other options
2.) When cranking it doesn't even try, just like you would expect with no spark.
3.) I poured fuel in the intake and in the cylinder and it did nothing!
It has to burn when ignited.
I have already swapped out the ICU which I believe is what you are calling the EZL. I did clean the cap and rotor with a wire brush. But I will replace Cap, Rotor and coil. We'll see what happens.

Thanks for the suggestions.

Also, I am in need of a 1170708732. This is the fuel line from the WUR to the fuel distributor. Local MB dealer says no longer available. Unless someone has one I need to find a tool to make the flaired end if anyone knows what that shape is called or find a fitting that fits on the WUR to use a hose clamp if anyone might know the size and threads of that fitting.

Thanks again everyone for your help.
