I have replaced the fuel pump and fuel filter, I now have 60lbs at the rail but holds pressure when turning over, good spark but I dont think the injectors are opening.

If its a TBI you can see the injectors spraying when cranking it over-Spider injection-check the plugs if its wet from fuel or open the upper plenum and remove a poppet valve and crank engine-before you do this disable the coil
