I have dug some more through Mitchell, at my friends shop, the spacs for the EHA looh dead on, for a 1991 500sl. So I guess there is quite a bit of difference in the models.

I did more probing around, and I found that #1 injector is not getting any fuel in. Funny, when I started this, all of them were getting fuel, including #1. I checked the fuel distrubutor and nothing is coming out of there as well at #1. I guess were back to the distributor, I just can't figure out how an 8 cylinder engine would not start on 7 cylinders...

Is it possible that fuel is metered before this happens, so the end result is more fuel to the remaining 7 injectors, resulting in the overfueling? I'm really starting to dislike this Bosh solution, reminds me of the old Lucas injection problems....
