If the ABS is coming on, it could be your OVP relay. Jump it with an in-line fuse and see if that starts her up. It could also be your ABS system.

When you say you hear the pump cycling, do you mean it's coming off and on?

Also, just because you have gas out of the fuel line doesn't mean you have plenty of pressure; granted, I don't know much about MB's, but there are plenty of domestics that won't run or start if the pressure is 55lbs instead of 60.

Again, with the ether not starting it up or running it, it makes it sound like it's still a spark issue. Get a timing light!
