Have an 03 6.0. During the winter, it was taking longer to crank to start but just figured it was because of the temps. Then as it got warmer, it still took at least two key cycles before it would start. Tried to start it the other day and it just continues to crank, never fires. No smoke comes out while cranking. I hooked up edge insight cs to it yesterday and came up with no DTC's. This evening I'm going to check the voltage at the FICM with multimeter. If the FICM checks out to be ok, what next? Pull fuel filter and see if bowl fills up when I turn key? Any other ideas what it could be?
