You did everything?

The last two of the chart is replace ecm. Replace main relay. You did both of those?

yup thats what i did, but if check engine light aint coming on that means ecm is not on which means no signal will be sent to fuel pump? right?
Maybe. Or maybe the Check Engine bulb is burned out or missing. Did it come on before when you first turned the key and it recently changes when this issue started?

Test resistance of blue/black wire from main relay to ecm. myredvert is right about bulb being burned out at times.

All this testing. Is the battery fully charged and battery cables tight and clean? If the relays turned on then you should be getting power to the pink fuel pump wire under the seat if in fact what you have said above is true about the wires having voltage at the relay.

I apologize, let rephrase that last comment. I tested all relays out of the relays socket. yes battery is good, the car is turning over fine, it just does not start.
