What could cause the truck to not start all of a sudden?

Question

Reader says data link malfunction. Originally it was driving- it started losing power. Got home-changed battery, starter, mass air flow sensor, and throttle body actuator module… and it still will not start.

Answer 1

Unfortunately, there are so many things that could cause a no-start problem. From spark plugs, to the fuel pump or even the PCM. Have you noticed what is missing when you crank the engine? fuel or spark? Do you have fuel pressure? Do you have any engine codes?
