09 Corolla won't start, no power to fuel pump

#1
My 09 Corolla ran great up and down the ramps to change the oil yesterday, then today won't start. It cranks and every once in a while hiccups like it's going to run, but does not. I cannot hear the fuel pump running and confirmed this with the seat off. The fuses all look good, and I even swapped out the EFI 1 and 2 fuses for good measure...no change.

Here are the symptoms and steps taken so far:
  • Car doesn't start, but cranks
  • Has spark
  • Fires for a moment but runs rough, even on starting fluid. Doesn't seem to run as long as it should
  • Builds 45+ PSI fuel pressure when activated manually
  • Fuel pump does not run at all when key is switched on
  • Fuel pump runs when activated through Solus scanner, so all wiring through the computer and to the pump is good
  • Swapped the blue 5 prong relay at the drivers side with no change
  • All fuses good

So 2 questions:
  1. What would kill the fuel pump outside of what has been checked. Inertia switches?
  2. Would this also make it run poorly on starting fluid?

Seabeeman,

Was there a resolution to this issue? I'm having issues with my 2013 where it will start after a few trys and I can rev it up to 4k then it dies about 5 seconds after starting. I pulled the back seat and felt the fuel pump and didnt hear of feel anything...
