Is there reasonable spark at the plugs?
Is the measured fuel pressure within specs on the new pump?
If those are present, and you have access to a 'noid light or even an analog multimeter the fuel injector harness can be probed to see if injector pulses are present during cranking.

Get some carb cleaner and spray into the intake while someone cranks the vehicle......if the car starts and runs as long as you spray, it's a fuel delivery problem.......
If the fuel pressure is ok, then the injectors are not firing and that makes it sound like a Theft/Security problem......chances are a "B" code is set......most scanners and code readers can't read "B" codes....
