Did you check the timing belt, has it been changed? Can you hear the pump run when the key is first turned? Have you pulled the fuel line to check for flow? Check all fuses?

Not much to go on, but not much will kill a running engine.

Anything that would kill the engine, should show a code apart from the fuel pump or mechanical damage. The pump could still run, but not have enough pressure to start the car.

Did you check the codes before clearing them all? You may have erased the one needed for diagnosis and it may not return if the engine is not started.

If you have access to a fuel pressure tester, you can pull the hose from just behind the airbox (the one that bolts to the fuel rail) by removing the miniature clamp. If you unbolt the side at the rail, it may leak in cold temps.

If you have fuel pressure, check for spark, a tester can be rented for free at AutoZone. You can also rent a compression tester if there is spark and fuel.

Check the voltage on both side of fuse 34. Also check the fuel pump relay, remove the cover and see if the contacts close when power is turned on.
The I think you have your supply/return lines mixed up. If no fuel is going in the supply line, no fuel could come out of the return.
