Help! my 190E 2.3 8V is DEAD!

Hello everyone, I recently got my car towed for driving while suspended, uninsured and unregistered (I know, I know, I've been a bad boy) and it was in the tow yard for seven (7) days while I made bail and made things right. It was lift-towed (Front tires lifted off the ground) when I was arrested, but flatbed-towed when delivered back to me. Here's the detail, now my car wont run. It is not my fuel pump or relay as those are new, so let me explain further. In the engine bay, I hear a loud noise of air being sucked and the engine dies out fairly quickly after that. The tow guy said it could easily be a vaccum leak, and he said maybe something's wrong with my intake manifold or its gasket. If anyone out there can lend a virtual hand, I would be most grateful and appreciative. Thanks in advance for any subsequent posts.
