The truck ran fine for and hour. Stopped it for 5 min. Tried to start, turned over fine but no start. Getting spark and gas to the throttle body but no gas from the injectors, what is keeping the injectors from firing?

Hi rpkjr77, Welcome to 2carpros and TY for the donation

Do you hear the fuel pump come on for 2secs? If so check the fuel pressure if its within specs if okay do below

Check injector fuse A if okay its either the computer fuel injector control circuit is defective or the computer is not getting an ignition reference signal to synchronize the injectors
