    Check the fuel pressure with a FUEL PRESSURE GAUGE while cranking.  Fuel pressure is zero or weak, check for power and ground at the FUEL PUMP by connecting a headlight bulb to the power and ground wires of the FUEL PUMP connector while cranking.  Headlight bulb lights up, the fuel pump is bad.

    The fuel ejectors should have one side that is hot 12 volt, constant. The actually operate by grounding out through the ECM. If there is not 12 volts hot (Black blue wire) then the problem is in the ignition switch, the main relay or a broke wire on the supply side.

    Take the air cleaner off of the throttle body and shoot a short blast of starting fluid into the throttle body and try starting it. Just because there is fuel in the fuel lines doesn't mean you have enough fuel pressure to start the motor. If it starts replace the fuel pump.

    Getting fuel is one thing, getting fuel at the correct fuel pressure is another.

    IIRC, correct pressure was around 50-55 PSI

      You can also check the oxygen sensor to see if it's cutting off fuel while idling: https://www.cars.com/articles/when-should-the-oxygen-sensor-be-replaced-1420663031800/
