Crazy Webb,

You need both pumps for the car to start/run correctly. The pumps work in concert, not as individual elements. If only one is working, there won't be sufficient fuel pressure for the car to start.

You may want to visit the W201 section of Benzworld. It is dedicated to 190's. This forum section is for W124 chassis cars.. 300E, E320, 400E, E420's etc..

Good Luck

Jayare

yes,make sure the the other pump is trully dead by tapping it with a rubber mallet and see if it comes to life.

my 300e wouldnt start until i changed the one pump that was pulling from fuel hose,tank side as it was dead.
