Truck stalling, not starting and sputtering

[NEHoss24]

after testing looking checking probing the wires and harnesses of the fuel system and being unable to duplicate the problem at the garage ( of course) I went with replacing the fuel pump relay on the firewall. It was the original and with any switch after a million or so times opening and closing I figured maybe it was just that worn out. Guess what truck starts every time and has not repeated any of its previous problems.

no, this is old

check the pick up hose that goes from the housing to the pump, mine was leaking and caused it not to run, these spider poppet injectors require 60psi in order to fire, thats why most people switch to the multiport newer spider injectors, they only require 30 psi
