Question type: Maintenance & Repair

I'm losing my mind on this one. I have a 97
ford f150 with 4.6L. I've replaced the coil
packs, plugs, wires, crank sensor, cam
sensor, and pcm and its still throwing red
spark and wont start. I dont know what else
will cause weak spark. Please help :(

Check timing if it has jumped time still will get spark and fuel but just will not start.
