87 red stand

i have a auto mustang that i had parked for about 5 years. when i parked it 5 years ago it was working fine...but now afters 5 years i put a new fuel pump wires spark plugs ect...and it wont past 20 miles an hour...it starts to slug and sometimes back fires....


but i was thinking also because 3 years ago i tryed to started and i notice that some of my pullys were stuck ...could that struggle make the car go off timing?? i need help badly
