Please help 300E cold start injector

Bad temperature sensor for fuel injection?

Thanks for answer. I checked all three sensor on the engin block and all fine. The four terminal one, which I think is for controller, looked fine. I measured values and they ran around 1Kohm when cold, and 200ohm when hot. I also measured voltage and looked fine.

BTW, the car runs well without having the cold start valve connected. It takes a little bit of more cranking like 5 seconds to start, but it's o.k. now. However, I need to fix that for winter.

Thank you very much ...

The cold start injector injects fuel for only a very brief period - seconds, not minutes. Currently it's this lack of fuel that delays the engine from starting. OK now but not so in January.
