My truck is getting hard to start when its warmed up.Like if I go out to dinner and the truck sits for 15 min. or so sometimes it doesn't start,but in the morning when I come out after it has set all night it starts right up, like it's brand new.I was stuck at the car wash for an hour last week,and then even worse I got stuck at the gas station after braggin to the guy behind me with a D-max,about how awesome my Cummins is.That dude had to go to an other station becuase I was blocking the pumps.
