Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Ok have you tested power at the pump two times , fist at key on and then at cranking ? The most common issue is the fuel pump relay. I will have to opt out right now as I don't have access to that diagram right at this moment and don't want to keep you waiting. I will check back later and if you are still needing help I will get you the info.
