I need some help here guys. 07 with 81,000 miles. I am starting to have rough starts. Cycling the key twice and the first try no start. The second time it will start and it is very rough. After a minute or so it is good to go so no idea what it could be. Just replaced the Glow Plug Module and had it at the dealer were they replaced the EGR and cooler. What noone can figure out is when i turn the truck off the injectors will continue to fire for around 30 seconds. Any Ideas? The dealership who worked on it last has no idea why they are still firing. I have a 2003 FICM, would it hurt to plug this in to see if it would fire and stop the after run of the injectors. I believe the fuel is building up on the pistons after they run and the fuel is making it have the rough start. Any Ideas please. About to drive this off a cliff. Thanks John
