FDCM symtoms?
Very occasionally my 4.6 doesn't seem to be getting fuel when I crank it. On those occations the starter cranks the engine fine, but it takes two or three attempts to accually start. 64K on the truck, and the fuel filter was changed about 10K ago, throttle body cleaned at the same time. Does this sound like a FDCM issue?

It's possible. Check the connections on the module. They get pretty corroded and could be causing it to start funny. Once started, how does the truck run? No problems with it dying while going down the road? If it runs okay my guess is that it is something else. Alot of people had problems with the module when giving it gas. Check to make sure you can hear the pump turn on, even the times the truck doesn't start.
