190E Fuel Pump, Fuel Filter problem?
 

I just got stranded 2 miles from home. My 190E had a little trouble starting, idled rough, sputtered, gagged, and stalled. Further attempts yielded the same results. Does this seem to be a fuel filter, fuel pump problem? Any direction would be greatly appreciated.

thanks,

John

Could be, and don't forget pressure regulator and leaks as part of the loop. Could also be spark, though. If you crank it a bit without starting, then quickly remove and sniff a spark plug, a gas odor indicates ignition issues, fuel system likely ok.

Most of the time the problem is the Klima relay (marked 4yzl), small black box behind the battery - the one close to the fire wall that controls fuel pump. It happened to my '85 190E 2.3. No problem after I changed it.

Are you sure the klima relay controls the fuel pump? I am pretty sure it is the relay in front of the klima relay. They look the same however have different pin configurations. I am 99% sure that the klima relay only has to do with climate control and compressor.
