I have a 2001 Ford F250 6.8l v10, on my way home today I turn 4h on and everything worked like it should, turned it off when I didn't need it anymore, when I got home I left the truck running because I had to leave again, I put my truck back in 4h and nothing happen, the light won't turn on and you can't hear the vacuum. I checked my vacuum lines they are fine.

Check fuses and relay s first then have it scanned there may be acode that will pop up. A pro may have to scan it as it may be the gem module is screwed up.
