Chevrolet Repair: 88 firebird, pontiac firebird formula, pontiac firebird

Question
I have a 1988 Pontiac Firebird Formula with a 5.0 liter. It will start then stall. If I step on the gas it stalls. If I pump the pedal I can keep it running. It will stall if I hold the pedal down or no pedal at all. Fuel pump going? No check engine light or trouble codes detected.  

Answer
Fuel injected or carburated ?. If fuel injected, How many injectors, 2 or 8 ?.


What mechanical work or ANY kind of work has been performed on the vehicle recently ?. As most problems that occur after a recent repair was made can be traced back to the area of where the repair was made as a vacuum line may have been knocked loose or a wire connection came loose, Look around in the area where work was performed..
