6.0 won't start

[SCJScott]

Ok, here's what I have. '06 F250 Fx4 6.0 30k, owned for 4 yrs. Banks cat-back exhaust and Banks programmer. Everything else is stock. Never had any problems until now. Truck starts right up every time in the morning (not that cold in So. Calif.) While at stop light, the RPMs would fluctuate just slightly but no loss of power or stalling. Park the truck, and when I try and start it again, it just cranks. 2 times prior, it would start but it would sound like it wasn't running on all cylinders. When I would push the accelerator pedal down, nothing would happen. Ford dealer said the truck starts right up every time they check it and doesn't show any codes. All electrical wires check out good. I changed fuel filters last month and changed oil (only use Motorcraft parts). I also use Rev-X additive for Chevron fuel. Ford has no clue what it may be. Anybody experience this? Help!
Thanks,

Scott

The only real way to catch this is with a scanner doing a live data log and see what the sensors are telling the PCM at the time of the problem.

Ive seen faulty ICP with no codes. However the pushing the throttle with no response is kinda odd.

accelerator pedal? Next time u get no throttle response try tapping/beating/hitting on the pedal. They have a sensor that goes bad, my truck has had it replaced twice already

Ford told me it needs to be diagnosed when the problem occurs. Funny, that's the reason why I left it there to no avail. I only have no throttle response when it starts and sounds like it's not firing on all cylinders. Now that was only once in a while. It was last Friday when I drove to Ford to buy the EGR gasket kit it wouldn't start, just crank. Maybe there is dirt in one/both of my fuel filters? Ford did update programs on the PCM,TCM and FICM and it shows it's getting better fuel mileage. Maybe I should buy a scanner?
