Starts & runs fine for a few minutes then Car stalls
 

I have a 1985 230ce with 252000km from germany. it had starter issues & i now use a start switch to start it. it starts fine runs great for a few minutes then stalls. the fuel pump starts to strugle when engine gets to temps of around 80celcius makes noise then stalls like it cant pump forward anymore. i've replaced the fuel pump, fuel filter, tried disconnecting the sensors on the block. i.ve cleaned the tank & lines. it takes a longer time to stall if the cars on the road. pliz help!?

Fuel Pump Relay perhaps?

Does the car stall no matter where the throttle is or only when it is trying to idle? If it is anything like my '84 BMW's injection, and it is only stalling at idle try cleaning out the idle control valve. Take it off and run some carb cleaner through it. also check all the vacuum lines as they can really effect the idle of the car once it warms up...

Good luck

Temperature sensors and idle control valve.....solved the issue on our 300E...

resoldering the fuel pump relay solved my problem
