    I have a '91 190e 2.3, had the same problem, turned it was the 10amp fuse in the fuel pump relay, it's behind the battery. Remove the cover and there are 2 modules and 3 relays. Mine was a silver relay in the middle with a hinged transparent plastic top. Opened the top, popped the fuse and problem solved. So much trouble and a 50 cent fix.

    the silver relay is not the fuel pump relay but the voltage overload relay,i would bet $1400 dollars its simply the cold start injector.go to a wrecker and take the centre injector with the electric plug and replace yours.it will start perfect i almost gaurantee it.
