Hi all need some help. My 87 6.9 was running perfect. Every mourning hit the manual glow for 12 seconds start and go. The other mourning out of the blue when I started it, it started and died. Had to crank the crap out of it. I even had to use some starter fluid. Once running it ran perfect with no problem restarting. Let it sit for enough time (onernight) and the same thing happens. I assumed it had to be air getting in so I made sure everything was sealed tight and dry. There is no wet or moisture anywhere that I can find. Any ideas?
