Put a new engine in, it will crank but immediately shuts off and when I push the gas it shuts off. While it runs for a moment it does nothing but shuts off when I push the gas.

Is the check engine light on when engine is running? Were any changes made to the throttle and intake manifold? Check all wire connectors, ground circuits for proper installation. Air flow sensor, hoses and related components have to be installed correctly. Any vacuum or improper air flow pass the air-flow sensor can result in the stalling symptoms described.
