Question about 1987 Mercedes-Benz 300-Class
Hello, I have 87 300e , the cold valve injector keeps spraying fuel inside intake, everytime the engine is at normal oparating temp. cousing to flatt the engine resault hard time starting long crank. If cold starts no problems. I have replaced fuel pump relay, fuel accumulator, injectors, temp sensors,check valves,fuel pumps,cold valve injector,over load protection relay so far no luck still the same problem. Do you have any ideas what it could be please? Thanks.
If you have an electric cold start valve make sure to unplug it and if keeps apling fuel with electrical conector unpluged that means the valve is not good, but if not then you have an electronic problem, possible a bad cold start sensor or cold start module or cicuit problem, and might be a time to take it to an electrical shop
