1992 190E 2.3 Cold Start

will turn over then die. This happens about 4 times then it will stay on. Whenever the car sits for about an hour, it does the same as above. Not the fuel pump, it was replaced. Any ideas?

Fuel Pump Relay.

Cossie, So what does that mean? The Fuel Pump was replaced a year ago? Do I need to buy another one or do you make some sort of adjustment on it? Thanks for the help.

The fuel pump and the fuel pump relay are two different things. The relay is known to go bad on these cars (it did on mine), and that failure can manifest itself in various ways, one of which you described as your problem. When mine went out, it started by stalling right after start up, then after the second start it would run fine. Then after a while it started to get worse, until the car quit while cruising down the road at 50 mph - just like I had turned off the key. I put in a new fuel pump relay (this was about 3 years ago) and haven't had a problem since.

The relay is a cigarette sized black box that plugs into a socket under the hood (not sure of the exact position in your car - either by the fuse box or behind the battery.

Bill, Just want to thank you! Bought the Fuel Pump Relay off the internet ($117 vs $175 @Mercedes), put it in myself and the car has been fine since. Thanks again, Jon
