Hi folks. After a long drive I stopped my w124 230te '91 outside my house and let the engine run on idle. Suddenly the engine stopped and I cant get it started again.
I have searched forums for what it could be and the fuel relay + fuel pumps was suggested to check out first.
An easy way to check the relay and pumps together was suggested:
-Remove the fuel return hose from the injection unit and mount a small piece
of hose to where the return hose was sitting.
-Put the new hose into a 2 liter container and turn the ignition on.
If the relay is ok the pumps will start up, and if the pumps are ok, they will pump about 1 liter in 40 seconds.
I watched a couple of videos on youtube where this was done and the pumps keep going with only ignition on. (not engine started)
-When I turn on the ignition I hear a relay click and the pumps start running.
but after 1 or 2 seconds the fuel pumps stops. I can hear something making a clicking noise first, and then the fuel relay clicks of and the pumps stop.
If I floor the gas pedal and turn key all the way, the engine manages to start for a second before stopping. something shuts off the relay.??
It seems like the relay and pumps are ok, I get a lot of fuel in the container for that short time running.
I would really appreciate getting some ideas on what this could be !!!
Thanks!
