I have to crank it for about 4-5 seconds then it starts for about 1/2 second and then dies. I opened the bleeder screw and with 1 pump out came desiel. Tightened it back up and still no start. I have no chek engine lights, no flashing security lights, fuel filter is tight and has about 2000 miles on it since I got the new bigger one from the dealer. 1/2 tank of fuel, about 40 degrees outside. Any ideas?
