Ok drove my car in the day (its a 02 c270) fine got back in it later turned the key started for a split second then conked out? Turned the key again it turned over the automatic amount of times but didnt start and so on? Seems not to be firing at all which leads me to think fuel isnt getting there whats the best way to check? take a fuel line off the rail see if its coming out? could i of got an air lock ? how easy is it to bleed?
