Does the ignition have spark? Please follow this guide to confirm the ignition working.

"THE LIGHT ARE NOT COME FROM KEY TO PUMP RELAY "
Do you mean the fuel pump relay is not getting power? But you mentioned hot wiring the fuel pump and it did not work.
Are there power supply to the fuel injectors?
Is the fuel pump that is not working or it is only the fuel injectors?
Did you check for trouble codes?
If there is a fault with the cam sensor, the fuel injectors would not work.

P1603 is a communication fault between the ECM and TCM and the most common cause is a blown fuse or bad wiring connections. Worst case scenario is a faulty Control Unit.
You mentioned the MIL indicating for a 2 seconds and engine will fire after which it would cut off. Did you test the fuel injector wire connector for battery voltage at one of the wires. Sorry I do not have the wiring color nor pin location to be sure which is the exact one. When engine stalled or could not be started, there must be battery voltage. The other is for the Engine Control Unit to ground the circuit to operate the injector.
Possible causes for this are :
1. Faulty relay, engine control and/or fuel pump
2. Faulty Engine Control Unit.
3. Fault with Immobilizer ( if equipped)
4. A bad ignition switch.
5. Bad ground or wiring connections.
6. A bad camshaft sensor.
Check all ground connections. Disconnect the ECM and check for clean and tight connections. Are there any more trouble codes present? Check the live data of the crank and cam sensors to see if they are working.
