My 2001 was cutting out so I was told to change the fuel filter, so I did and now it will not start. I took it apart Sunday afternoon and found out a filter for a 99 will not work. When I got the correct filter this morning it would not start after I installed the filter. So far I have loosened three of the lines by the valve cover and tried to bleed the air at the at the two valves. I was told before I changed the filter that the lift pump may be bad. The truck is a rebuilder so it does not have warrenty that I know of. I also left the water drain open and turned the key off and on and did not see any fuel running out.
