Fuel 1986 GT 5.0 stalls unless pumping gas pedal

[SwiftNuva]

My 1986 mustang barely starts unless using starter fluid. Once started. It dies unless you pump the gas pedal repeatedly. If you floor the pedal it doesn’t rev at all and just dies. Just replaced spark plugs, fuel filter and air filter. What else could be wrong?
