To replace the ignition switch remove the horn pad be careful the wire is still attached to the turn signal switch the plastic piece push down and turn it comes out then remove snap ring on the end off the steering wheel then nut place a dot of finger nail polish on the shaft and wheel for alignment purposes use a steering wheel puller once off then install a lock plate puller compress down and remove lock ring once removed (lock plate) this is spline d to go on one way then take the cancel cam off (slides off) remove turn signal lever screw and turn signal screws lift up to gain access to the ignition switch retaining bolt a small piece of plastic is covering the screw that is the key buzzer switch it just pulls out be careful not to drop the spring steel retainer down the column it does not come out that easy and does not install that easy either. Place ignition in the on position remove and put the new one in the same way this allows the key buzzer to go in with out interference from the plastic shoe that's part of the switch. the lock plate tool can be rented from the parts store.

look directly under the switch where the key goes in. there should be a small hole. Insert the key into the ignition then find a pin or a small tool that will fit into the hole. press it inward and this will release the lock that holds the keyswitch in.

You replaced the starter and solenoid. Did you check to see if you have battery power at the large starter post, and on the small wire coming from the key switch ?
