SOME CYLINDERS NOT RUNNING

1999 GMC Savana

Engine Performance problem
1999 GMC Savana V8 Two Wheel Drive Automatic 250000 miles

cylinders 5 8 and 2 don't seem to run at all but they spark when I unplug the wire. I put new cap roter plugs and wires. I also replaced the feul injector on cylinder 5 but no better?
