Okay. That is good but let's check the fuel pressure anyway because it could be other things then the pump itself.
Also, try doing a clear flood start. Hold the accelerator to the floor and try to start the engine. This may be a leaking injector causing a rich condition until it clears up.
If this is the case then the fuel pressure will show correct when the key is turned on and then the pressure will bleed off quickly.
If there is too much fuel then it will crank until it clears the cylinders of fuel and then the mixture will be able to ignite and start the truck.
