Leaking injectors (most likely), Fpr solenoid or low compression.

It's called the Pressure regulator control valve in the FSM. It boosts the fuel pressure on hot starts for a period of 60 to 90 seconds or so depending upon whether you have a turbo or NA. There should be no pressure on the vacuum hose to the FPR (Orange solenoid) during a hot start.
