96 350 vortec has 63lbs of fuel pressure as soon as u turn the key on but drops to 58 rapidly and it runs horrible when u floor the gas pedal please help

when you try to floor it it spits and sputters and cuts out and when under a load runs bad what would cause my fuel pressure to do that and do u think thats my issue ive changed distributor, coil, plugs, wires, cap, rotor, crank sensor, temp sensor, and maf sensor I cant seem to figure it out please help me thanks

Do you have a check engine light On or has flashed -if so scan the computer for code/s if any present post them

Lets start by verifying the fuel pressure if its within specs and report back the readings
