I'm pretty sure the fuel pump is bad, and I've ordered a repair kit for it, but I wanted to see if someone has another idea:

In the morning, 7am, when it's still 40 degrees outside, I can get my truck started. Fires right up. After the temperature warms up a bit or later in the afternoon, the truck won't start.

When I turn the key in the on position, then pump sounds like it tries to pressurize the system, but "whirs" to a stop after about a half a second - and fuel pressure stays at zero. There is 11.84 (ish) volts to the pump during that time. I'm going to take off the bed today and pull the pump and see if it needs to be cleaned or something, also in anticipation of repairing it. If anyone has any other ideas, I'm all ears.

The wiring connectors on the pump are notirous for causing issues.
