I have a '96 E300D diesel and am having a starting problem. Sometimes the car will start normally and other times when I try to start the engine, I get no response from the starter. Most times after repeated trying the started will crank the engine. I've checked the starter lockout switch and it's OK. When the starter will not crank all other electrical is OK. I suspect the starter solenoid may be defective. Does anyone know if it is replaceable or Do I have to replace the whole starter. Or is there another part in the chain that may be defective. Unfortunately, no manuals are available for this model. Thank for any help.
