Any thoughts would be appreciated.....
Hi guys, im new here. '05 F350 5-speed. A few weeks ago I was driving down the road and the truck just shut off and wouldn't restart, so I had it towed home and it still wouldn't start. I unhooked the batteries and let it sit over night went out the next day and hooked them back up, low and behold it started rite up. It ran rough(which was what was usual since i didnt realized at the time the FICM was bad) but still idled and ran, I revved it up 2 or 3 times and on the last time it just shut off like I had turned off the key, then wouldnt restart. So after doing some testing and finding out the my FICM wasnt putting out the rite voltages I sent it to FICMrepair.com and had it fixed. It came back, I tried starting and still no start, so I went to what seemed to be the next common issues the IPR and the STC fitting, the screen was broke on my IPR, so I replaced the IPR. I replaced the STC fitting which was loose but not falling apart. Then after putting everything back together I hit the key and It fired up, took some cranking but I attributed that to having so much taken apart and things needing to get primed back up. Then I revved it up a couple time and low and behold it shut off again and wouldnt restart. So could anyone give me any ideas of were to look from here? Thanks
