what are all the causes of no power to fuel pump in a 2002 pontiac sunfire?

the fuse, then the relay, and then the pump,that's the only three things really on it that will cause it not too work properly,check for power at the fuse panel and then go to the relay than go back to the pump and check for power there,if there is no power you have lost it somewhere in the front of the car,the most common cause is a blown fuse ,good luck.
 
Not sure about your particular model - may also want to verify whether there's an inertia switch cutoff. This is in place on some vehicles for collision safety, the jarring motion will shut the fuel pump off.

My Ford truck has one - as far as I can tell, my '88 Grand Prix doesn't.
