89 EB Bronco will not start!

1989 sull size Bronco EB will not start. The key has always been hard to turn, but will not work at all now. We were able to start it by jumping the coil with screwdriver, but now that doesn’t work. Have replaced the starter solenoid, and ignition switch, no help. Have check the fuel filter, etc. It cranks, but will not start. Help!!!!

did you try replacing the ignition switch or the tumbler?

I'm actually having the same problem but my ignition works...just sounds like the starter won't engage...replaced the starter, starter solenoid, ignition tumbler and switch, all the cables from the batter to solenoid and ground, and the battery itself. Still doing the exact same thing since the day I got it here (had to push start it to drive it home).

'84 Bronco II 2.8 v6. Out of options, flywheel looks fine too.
