I have changed the fuel pump and replaced the filter and checked the ground connection. The truck will start but shuts off. What could be the problem?

Is it a preeure problem? Check the pressure regulator on the fuel rail, unplug the vacuum hose, if there is any gas in there the regulator is NG, Also see if any codes are stored, do this by turning the key from off to on four times and leave it on the last turn to on. Count the blinks, 22 will count as 2 blinks then a pause then 2 more blinks. 55 will be the end of your codes. Post the results here!
