that the CKP (crank shaft position) sensor is working. The fuel pump relay will not trip without the signal from CKP sensor.

Does the engine fire up every time you use starting gas, or was in only one time and never again?

If engine fire up every time using start gas, we can pretty much be sure that you have spark too, and rule out an ignition problem.

That leaves us with the injectors supplying fuel to the engine.

I'm not at work today, so I can't promise that I pull the info out of my head correctly, but.
I think to remember that the fuel pump relay also supply power to fuel injectors by triggering a second relay. Is it a chance that the fuel pump relay you installed only "looked" the same but the pin numbers are different? In that case, the relay may not trigger the second relay and so forth not supply power to the injectors?

Try to remove one of the injector connectors and measure for voltage on one of the two leads while someone cranks over the engine.

If I remember correctly, one pin should have steady battery voltage while cranking and the other pin should have a pulsing ground determined by the fuel ECU. Use a regular test light to check with.
