Hello community! I am currently working on an SL 380, built in 1981, American version. The car starts, and goes out after 3 seconds. In good old tradition only ignition sparks measured, was there. After that fuel pressure, pressure gauge connected to the cold start valve of the K-Jetronic. When I bridge the pump relay, a pressure indicator of over 10 bar, i.e. almost stop, surprised me. Also another pressure gauge brought the same display. I also hear loud flow noises at d the pump. Since I suspect an overpressure valve on the fuel pump, I hit the pump with a rubber hammer, the pressure slowly migrates to 8 bar. I assume that the error is due here. What effects does a too high pressure on the injection system have on it? Differently asked: can damage already be caused? Greeting
