Mr P: Since I have a switch that turns on the ignition/computer and fuel pump seperately, I can try to start the truck for a few seconds to "clean out any fuel" that may be accumulating as you are suspecting. Without the fuel pump on, the rails, injectors and cylinders should now be clean of fuel. I will wait a fuel hours and try again.

It acts as if it is a ground problem or loose connection or too much timing... Except, as I mentioned before, when I first try to start, it turns over slowly. But after the initial try, if I turn the key to off, then back to try and start it, it turns over easily.

Maybe I will make a vid/sound clip this evening.
