i need a few clues to this benz. it turns over but won't fire. i even got the CDs(manual) but it don't give the basics. i pulled all the plugs and had sparks. so i pulled the fuel line coming into the electrohydraulic actuator, got fuel. pulled one of the lines leaving the fuel distributor, no fuel. but there is fuel from the cold start valve. should gas come out of the dist. during cranking? the fuel pump only stays on for a few seconds when you first turn the key. help
