If it wasn't the fuel pump, then the car would run briefly and then shut off when the fuel pump relay was bypassed and 12v was sent to the pump itself, right?  Just like it did with starting fluid.....

Hold the phone!

In order to run, the FP must get the signal that the CPS is doing it's job.

But if you don't get the dreaded CPS code, and you're still no fuel, I
can't see any other option but to replace the FP.

Especially if you've applied power directly to the FP and still got no
action.  As in, got no fuel pumping to the front of the car.  That's
something I would check by taking a line loose and doing the
pump-jumpering thing.
