I am also having cold starting problems here in northern Illinois. (Got to 39 last night) Recently replaced the battery. Do I have one of these OVP fuses too? Where is it on a 190e? I am very new to MB fuel injection and don't know where to begin. Haynes says, "Don't try this at home" Take your fuel inj. trouble shooting to a dealer. I was going to replace the fuel filter but this seems to be an easier first step. (and cheaper)
