I decided to drain the fuel tank and the firast6 5 gallons were dark yellow and stunk, second bucket LOL, was light blue, DIESEL FUAL, That bonehead friend of his put diesel in a gas car and Mercedes has so many places fuel goes before it even reaches the engine. I tried draining all the lines I could but still no start, This is a job for a Mercedes Mechanic, beyond what I can do,,,,,,,,
