The 1985 Mercedes 190e could have a stuck choke. Check the choke mechanisms to start with, to see if that's the problem.
May be (probably) the cold start valve. I'm not sure how to check it to see if that's the problem. They are expensive even if purchased aftermarket. Good luck!
This is probably a separate issue. Most 190e's with the 2.6l engine are known to be rather troublesome in cold, and wet weather. As I live in Maine, we get a lot of that... The most common solution is to replace the cold start sensor. This will keep you from having to give your car a shot of starting fluid every time you want to go somewhere.
Does the engine turn over but not start or it does not turn over till cold? If the latter is the answer then your kick start is the problem. REPLY The car turns over but wont start.
its too cold
Could be a number of reasons. Visit www.mercedes190.co.uk
Most diesel engines are hard to start when it is cold. Plugging the diesel engine block heater in will help the engine start.
who give the signal in the 5th injector to start 1992 Mercedes Benz 190e 2.3
It is not so much hard for a car to start when the engine is cold as it is easier for a car to start when the engine is warm.Cars that are hard to start in the cold are usually not new cars any more and because of wear and tear there is more likely to be something that doesnt work as well. when fuel is warm it ignites more easily.
Cold start valve is bad or possibly blown fuse in overload protection relay
They seem to freeze a little in cold weather.
It means it is very hard to start and keep running in cold weather.
