SOURCE: good fuel pump, engine turns over but wont crank.
if u pour fuel in the throttle body n cranks then goes dead u may want to check your fuel injectors see if they're actually working , u say your fuel pump is good maybe not the injectors

Can try doing a relearn process, it is pretty simple and will take 30 minutes, if it'll work for you at all since your problem doesn't sound like a computer issue.
30-Minute Learn Procedure
1. Turn on the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON; the vehicle will not start.
3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF.
4. Turn OFF the ignition switch, and wait 5 seconds.
5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes.
The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK.
Important:
Turn the Ignition Switch OFF.
The vehicle learns the Passlock Sensor Data Code and/or password on
the next ignition switch transition from OFF to CRANK. You must turn the ignition
OFF before attempting to start the vehicle.
6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code
and/or password.
7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100
ignition cycles.
Without a scan tool you may have momentary starter interruptions while history clears itself.
Good luck and hope this help's. keep me posted if you need other ways to disable the passive lock system
SOURCE: truck won't start. engine turns over. checked
have someone to stand back by the truck why you turn the key to listen to hear if there is noise coming from the gas tank if it is then its not the pump then it maybe your fuel pump relay or the crank sensor give these websites a try www.alldatadiy.com and www.autozone.com wish you the best of luck Michigan Man.

Normally, when you twist the key to ignition, you should hear a fade sound of the fuel pump pushing fuel to the tubes. If you don't check fro fuse or in the worst case scenario, you have a dead pump. That will mean you need to pull off your fuel tank and remove the pump from inside there.

I would guess fuel pump. Have you checked fuel pressure?
