my bosses truck decided it didn't want to start the other day. its a 2004 f-350 with the 6 litre powerstroke and 206 000 km. its cranking over and it may fire once or twice but wont start.

its been acting weird for the last couple months and the ford dealer cant seem to fix the problem. occasionally it wont idle below 1200 rpm and if you try driving with it idling high the transmission slams into reverse and slips like crazy in drive. after it idles down it will drive fine.

it will sometimes downshift really hard while driving for no reason at all. when it does the tow haul light will start flashing on and off.

sometimes it wouldn't crank over when you try to start it. let it sit for half an hour it will start right up, or cross the starter solenoid terminals and it starts.

it has been to the ford dealer many times and every time they replace something but it doesn't fix the problem. i replaced both fuel filters which were black, and attempted to drain the water separator but was unable to remove the drain plug. ford ended up replacing the separator because of a few solenoids not working? the also did some transmission work because they said some sensors or solenoids weren't working.

nothing has fixed any problems and now it wont start at all. i scanned it and no codes came up.

any advice is greatly appreciated.

 

I would recommend beginning with the no-start thread in the Tech folder

You are going to need information (ICP readings, IPR readings, FICM readings, Sync, etc).

 

What they say and what's really going on are two seperate things. I would also suggest the no-start thread.
