Answer
Hello Jason,
Without testing the fuel pressure, you can't say it is good enough.
It MUST hold 13 to 14 PSI at the throttle body when running.
The injectors are only solenoid valves, and need the pressure to force fuel thru them when they open.

If you have 13 PSI, then the ECM may not be pulsing the injectors, or the injector fuse is blown. See if power is getting to the injectors. Should be battery voltage when the key is in run.
