    Does it backfire when you stop cranking the engine? I had this happen on a 03 FX. I could crank and crank and as soon as I let go of the button, backfire...even blew the hose off the waterbox. Had to clean out the drawers on that one. Unplug the idle bypass control valve and see if it starts. If it does the valve is bad. Took me a while to find this one.

    Either Coils are not connected properly or icv is bad....
