The problem, more than likely, is the ignition lock cylinder housing on the steering column. The ignition key cylinder is on the right side and the ignition switch in on the left side. The inner rods are known for breaking down causing poor mechanical connection between the key cylinder and the ignition switch. You can verify this by removing the trim panels on the steering column and removing the ignition switch and plugging it into the electrical connector and use a small screwdriver to turn the ignition switch and see if the engine starts. If it does start, have the ignition lock cylinder housing replaced. It comes with a new ignition switch and you transfer your original key cylinder to the new housing.
Yes. The brake shift interlock system goes through the ignition switch.
That is why I asked you to verify the cause by removing the ignition switch and turning the switch with a small screwdriver and see if the vehicle starts. See below.
