In '03 FL truck (fairly new to us). If using regularly, usually starts fine. If it sits for a few days, have to crank for a LONG time to get it to fire. Where to start?
O/H'd one in a '98 KW last winter, and don't remember seeing any check valves in what I took off (pretty much everything). Service manual says to hook up to computer first.
C-12 Cat Fuel check valve?
