Robert,
Please be more specific.
If it cranks and does not fire and it is a throttle body 454, then get a timing light and hook it up to an plug wire.
With air filter open, crank with the timing light on.
If it flashes, you have spark.
If it does then you should be able to see the fuel stream in the flash.
If there is no fuel stream visible, get someone to put an ear on the fuel fill while you turn the ignition on.
Can he hear the fuel pump run? Yes/No
That is the first 100$ of diagnostic.....
