Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** has been tried or tested so far? Are you a technician at a shop?
Do you have any specific details for me to go on? Do you know specifically what they have tried?
Those items will cause difficulty filling the tank and could cause a no start under certain conditions. They would mainly cause a problem right after filling the tank. The shop will need to determine if there is fuel pressure in the lines and spark to the spark plugs when the car will not start. Once they determine that they can focus on the specific system. A faulty crankshaft sensor can cause no spark to the spark plugs and a faulty engine control unit or fuel pump could cause lack of fuel pressure.
