Some of this depends on if this is the older mechanical throttle body with a separate Idle Air Control (IAC) valve or the newer electronic throttle body ("throttle by wire")
Cleaning a throttle body is a waste of time. The software is designed to handle "sludged" throttle bodies as long as the plate still moves. (I wrote some of that.)
IAC issues usually results in crank-no start (flooded).
Cleaning the MAF can't hurt.
My gut says it is a fuel pressure issue, but the only way to know for sure is to connect a fuel pressure gauge and drive it while watching the pressure.
