6.0 Starting Problems

I am a diesel rookie but I now own a powerstroke 2006 F350 SuperDuty with a 6.0. I am experiencing a starting problem that I need your advice about. Everything has been going good until 2 days ago. I started to drive it and all of a sudden it started jerking and bucking like I had bad fuel going thru. Since I was at about at a 1/4 tank I thought that might be the problem so I stopped and put some fresh fuel in. Yesterday it ran find, no problems. Now today I can't get it to start.

Any suggestions as to my problem. All filters were changed last fall, along with oil change and coolant flush.

Thanks for your help.

Check the ficm voltage, you will need a monitor of some sort. ScangaugeII is available at Auto Zone for around $165.00 and monitors almost everything on the 6.0.

it needs to be in the 46-48 volt range to be solid if the truck has had a bad battery recently that will wipe out the ficm.

Start there plus engine needs to be in the 10+ volts during crank for it to start good. At 8.5 volts and lower it will not start, this can all be monitored by Scangauge.

I would change the fuel filters as well. Maybe you clogged them up running the tank low. Get a monitor and record Icp volts, IPR % and FICM with KOEO. I'd also find a way to check your fuel pressure.
