stator? What prompts you to look at the stator in midst of an obvious fuel system issue?
I'd urge you to get into your service manual section on fuel pump diagnosis...your answer will be found there. Very possibly a fault within the fuel pump relay...kind of the "brain" for the pump.
PS "looks good" generally doesn't cut the mustard in regards to electrical items integrity...specific tests exist using multimeters and such. Again, the service manual is your friend.
You DO have a service manual, right?
