Hi,
If you have spark and fuel, it should run unless the compression is low, or the timing is off. Will it start briefly if you use starting fluid? If it does, then we have a fuel-related issue. Although you are getting good fuel pressure, it may not be getting into the engine.
We need to make sure there is power to the fuel injectors. First, check fuse 7. See attached pic for location. Make sure the fuse is good and has power to and from it when the key is in the run position.

If that tests good, then we need to test for power at the injectors. If you look at the wiring schematic below, note that each injector has two wires. A pink wire at each injector is the power supply. Check that for power with the key in the run position. If there is power, we need to check for a ground path from the PCM.
The second wire, which can be a few different colors, is what needs to be checked. Disconnect the connector at an injector. Take a test light and attach the alligator clip to the battery positive. Probe the opposite color wire. Have a helper crank the engine. The test light should strobe on and off while the engine cranks.
Now, if the engine refuses to start with starting fluid, disregard the tests I provided. We will need to move on. Keep in mind, I am basing this on having an ignition spark at the spark plugs.
Take care and let me know what you find.
Joe
