my sienna is having intermittent stalls on a warm engine but runs fine on a cold engine.ive done a few things already:

cleaned out throttle body and MAF
changed air filter
checked and changed some spark plugs and coils
sprayed for vacuum leaks
all in that order
currently waiting on a fuel pressure reading
already saw that the LTFT is way out of spec

ive gathered whatever info i could that led me to think it is the fuel pump assembly which made sense because my wife drives it with the gas light on very often.

But my current issue that bugs me is this code C1201.

any thoughts on whats causing this code or if there is a differnt issue beside the fuel pump?
