03 FICM fuse

genuineford · May 24, 2012

Hi all, I keep blowing the FICM fuse on my 03 6.0. Can someone get me a diagram for that fuse under the dash so I can try and diagnose what is going on. When it pops the starter will not turn over and the fuel pump does not turn on. It also kills the obd port. If anyone has any experience with this it would be great. I was towing a vehicle at the time and it took about 12 fuses for me to get home, it would run sometimes for a few miles and sometimes for a 100 yards and sometimes for over an hour. Thanks

I was able to get a wireing diagram on this but haven't had time to look at it. Today on my way to work the fuse blew and when I replace it it blows again right away. Are their any hot spots to look at that their may be some wire chafing? I am going to try and dig into it tomorrow after I get up from work. Thanks.

I would amagine chaffing would be the problem, she's shorted somewhere..

I would imagine also it seems to be blowing when I hit the brakes and the front end dives or when I am on a rough road and hit a large bump.

I really hate it when I am stuck at work and have an issue like this.
