There is likely very stale gas in the lines from the tank to the injectors. Been there done that. The 4.5 will actually start as long as it can compress the first cylinder it hits - so if your engine is turning, even at a snail's pace, it'll start (also been there done that).

The thing I did was I pulled the line off the cold start valve, drained it into a gas can - key cycling from accessory to run a few times to cycle the pump. Do it until the fuel comes out clear and not yellow. It may take 10 to 20 key cycles. Then it should start easier.
