Ok, now I checked the spark plugs today after i have been trying to start it, and they was dry no fuel on them at all , but i have fuel at the rail. so dont that mean that the injectors are not working? someone has to have a clue here.

check to make sure all of the harness plugs are reconnected and that your grounds on the new manifold are tight. Have you upgraded to the Q45 TB. if so, check the wiring on the TPS and see if you are getting fuel pressure. Most likely you did something when you moved the fuel rail and unplugged the injectors.
