I would check the connectors at the pump first, make sure they are sealed properly

Well it may or may not, however seeing that it was the last thing you did before the issue took effect then i would go back to it, The next best suggestion i could recommend might cost you $14.95 go to www.alldatadiy.com this is an online repair manual that i've been using for years on all of my mercedes it is very informative not just a repair manual but it also gives trouble shooting, symtoms and solutions check it out.
