Pressure has nothing to do with the fuel pump turning off when you turn on the key. It is on a one second timer inside the computer.
Note that one second is longer than most people think.
The computer has no idea what the fuel pressure is at any time as there are no pressure sensors in the fuel system or pump.

You also need to see what codes are in the computer memory and see if the truck passes the electrical KOEO test.
Note that the computer memory (CM) will be cleared if the battery is disconnected.

Sounds like you have some open wires on top of the engine as the red wires should be hot all the time the key is on. The computer grounds the fuel injectors to fire them.

In post #19 above shows the self-test connector that has pin #6 in it. You can use that connector to count the flashes or you can use the CEL in the cluster to count the flashes of the codes.
Just ground the STI wire and turn on the key with the engine not running and count the flashes of CEL or test light. Make sure you get a paper and pin before starting so you can record the flashes.

The KOEO Electrical test is the first set of codes that are read out. Then there is a space (one flash) and then the CM is flashed out.
