I have a problem with my '88 190E. I tried to start it and it blew a 16 amp fuse -- number 8 I think (second fuse row from bottom, second from left).

I replaced the fuse but I can't get it to start. (I can't determine what part or module runs thru this fuse.) I have discovered that if I put a little gas in the carb that it will start, but will not keep running unless I pump the gas peddle and keep the RPM to about 4000. I've unplugged the cold start switch -- same thing; jumped the switch cable, and still the same thing. I can hear the fuel pump humming when I turn on the ignition (replaced the pump & filter about a year ago). A local tech said that it sounded like a vacuum problem. I did find a small vacuum leak and fixed it, but still no start. All I have is a Haynes manual and a multimeter for testing. The closest sure-enough MB shop with diagnostic equipment is about 75 miles away. Any ideas?

Thanks for your input.
