I recently bought the truck in my sig. After two days of driving it, it wont start. My buddy hit the valve on the side of the fuel filter once and it start but hasn't run since. Fuel smelled like gas so i poured oil/diesel mix to dilute it and changed the fuel filter filling it up with atf. It does not even act like it wants to start. Cracked injectors 2.4.6.8 and tried to see if any fuel was coming out 2,4,8 were noticably wet but nothing major and 6 was barely wet at all. Is my lift pump out or something else?

 

ok well um....first put another new fuel filter on this time filled with diesel and try to bleed the air out of the system...loosen all 8 injectors off untill the nut on the line will spin by hand...they should start squirting fuel out not just get wet...did it quit starting after you filled it up with fuel?...if yes drain the tank and refill with diesel...have you checked the lift pump pressure?
