02 F150 5.4. at times it wont start. When this occurs the gas gauge doesn't come up, as in the key is not on. if you turn engine over during this it will fire, off residual fuel, as have checked fuel pressure and there is none. Also at times the gauges in dash will go from all way over to all way down, , Again this is intermittent. Often let set for a bit and will start. I've replaced fuel pump/sender package in tank, ignition switch, fuel pump relay, theft module. Still occasionally will do this. Its a great truck and I love it. Need some help please.
