Steering wheel wont lock

The two problems may or may not be related. The problem with the steering wheel is probably from faulty or broken steering column locking pin or from the steering column assembly itself.

The not starting may have something to do with the key switch assembly as improperly installed into the steering column as the locking pin being faulty. Or it could be from lack of electrical current from the battery, or broken fuse/relay.

I would check the steering column assembly locking pin first.

Ignition Switch (Removal & Installation)
Disconnect and isolate negative battery cable.
On tilt columns, remove tilt lever.
On all models, remove upper and lower steering column covers.
Remove 3 Torx screws.
Gently pull s witch away from column.
Release connector locks on ignition, Key-In switch, and Halo light connectors.
Remove switch from connectors.
To install, reverse removal procedure

Lock Cylinder (Removal)
Remove ignition switch. With key inserted and ignition switch in LOCK position, depress lock cylinder retaining pin using a small screwdriver.
Rotate cylinder to OFF position.
Lock cylinder should now be unseated from ignition switch assembly.
Rotate cylinder counterclockwise to LOCK position and remove key.
Remove lock cylinder

Installation
1.Install electrical connectors on switch assembly. Position park lock slider linkage in mid-travel.

NOTE: On column shift vehicles, shifter must be in PARK position. Ignition switch must be in LOCK position (column lock flag parallel with ignition switch terminals).

2.Mount ignition switch to column. Tighten mounting screws to 17 INCH lbs. (2 N.m). Install upper and lower steering column covers. Install tilt lever (if equipped). Reconnect negative battery cable.

3.With lock cylinder and ignition switch in LOCK position, insert lock cylinder into switch assembly until it bottoms. Insert key. Gently push in on key while rotating key clockwise to end of travel. Check for proper operation of ignition switch in all positions

The fuses are labeled by number. What number fuse is it.

That fuse also supplies power to the FUEL PUMP RELAY. If the relay is the problem it could cause the fuse to blow. Try swapping the fuel pump relay with an identical relay (in the same fuse box you should have an identical one). If the problem goes way then replace that relay.
If not, check for a wire with a bare spot on it in the large group of wires which lead from the power distribution box near the battery. These wires go under the battery box and it has been found that sometimes battery acid leaks on them and corrodes away the insulation allowing the bare wire to touch the frame causing blown fuses and other problems.

REMOVAL & INSTALLATION

Ignition Lock Cylinder

CAUTION
The Supplemental Inflatable Restraint (SIR) system must be disarmed before working around the air bag or SIR wiring. Failure to do so may cause accidental deployment of the air bag, resulting in unnecessary SIR system repairs and/or personal injury.

Disconnect and isolate the negative battery cable from the battery.
In order to disarm the air bag system, allow the SIR system capacitor to discharge for at least 2 minutes, before performing any removal procedures.
Remove the screws that secure the parking brake release handle to the instrument panel.
Remove the screws that secure the bottom of the lower steering column cover to the instrument panel.
Disengage the retaining clip that holds the right side of the lower steering column cover to the instrument panel.
Remove the lower steering column cover from the vehicle.
Remove the mounting screws that hold the upper and lower steering column shrouds and remove the lower steering column shroud.
Install the ignition key and turn the key cylinder to the RUN position. This is important because it will not only aid in removal of the ignition lock, but will also place the socket (in the lock cylinder housing) in proper alignment for the installation of the replacement ignition lock.
Press in the lock cylinder retaining tab and remove the key cylinder (ignition lock).

To install:

Install the ignition key into the replacement ignition lock key cylinder. Turn the key to the RUN position. Depress the ignition lock key cylinder retaining tab.
Align the shaft at the end of the ignition lock cylinder with the socket in the end of the ignition lock cylinder housing.

Align the ignition lock cylinder with the grooves in the lock cylinder housing. Push the ignition lock cylinder into the housing until the retaining tab sticks through the opening in the lock cylinder housing.
Turn the ignition key to the OFF position and remove the key.
Install the lower steering column shroud and install the mounting screws.
Place the lower steering column cover into correct position on the lower instrument panel and engage the clip that secures the right side of the cover to the instrument panel.
Install the lower steering column mounting screws.
Install the mounting screws that hold the parking brake release handle to the instrument panel.
Reconnect the negative battery cable.

REMOVAL & INSTALLATION

Ignition Switch

Disconnect and isolate the negative battery cable from the battery.
Allow the SIR system capacitor to discharge for at least 2 minutes, before performing any removal procedures. The air bag system is now disabled.
Remove the key cylinder (ignition lock).
Using a No. 10 Torx  tamper proof bit, remove the ignition switch mounting screw.
Depress the ignition switch retaining tab and carefully pry the ignition switch from the steering column.
Disconnect the electrical connectors from the ignition switch and remove the switch from the vehicle.

To install:

Be sure the ignition switch is in the RUN position and the actuator shaft in the ignition lock housing is in the RUN position.
Reconnect the electrical connectors to the ignition switch.
Carefully install the ignition switch, making sure the ignition switch snaps over the retaining tabs.
Install and tighten the ignition switch mounting screw.
Install the key cylinder (ignition lock). Complete the installation by reversing the removal procedures.
Reconnect the negative battery cable.
Check switch operation.

Fuse #23 powers the ignition switch. That means that the switch or anything it powers can be the cause so you're going to have to start inspecting the switch and wiring looking for something shorted out. Overloads can be very hard to identify.

Try 2-A

There are 4 things that I see over and over again, that keep an ignition lock cylinder from turning.

1.
The steering wheel lock is under pressure.

When you turn off your car and remove your key.
A spring loaded post sticks up in to one of many holes in the steering wheel.
This locks the steering wheel in place, making your car harder to steal, because a bad guy cant turn the steering wheel if they somehow get your car started without the key.

But this can also keep you from turning the ignition lock.
If the steering wheel is under pressure because your front wheels are against a curb, or you have the wheel cranked all the way to one side or the other. The pressure from the steering wheel on the spring loaded post keeps you from being able to turn the key.

So while trying to pull the steering wheel one direction or the other, try to turn the key, this may solve your problem.

2-A.
The pins are not falling into place.

You kinda need to know how a lock works for this part.
Look at a key and you will see there are different depth cuts in it.
Those different cuts correspond with different length pins in the lock cylinder.
See how the red pins are of different length?
But with the key inserted, they are all even with the blue pins.

When the red pins are held in the correct position by the correct key, the spring loaded blue pins are flush with the outer housing of the lock, and the red pins are flush with the inner cylinder of the lock
And thus the inner cylinder can be rotated.

If debris such as pocket lint, ear wax, or just plain old dirt gets into the pins and causes enough friction for the spring loaded blue pins to not be able to push the red pins back in place.
Then the red pins will be partially stuck in the hole for the blue pins and the cylinder can not turn.

Putting the key in the lock and then tapping on it with a small hammer may help until you have the chance to have the lock cleaned.

Do a search for the word "bump key" if you want to know more about how a lock cylinder works.

2-B.
The same goes for if a key is worn out.
If a key is badly worn, then it will not put the red pins in the correct spot and some of the pins will keep the cylinder from turning.

If your key is worn out, try a spare if you have one.
Or put the key in and "Jiggle" it while trying to turn the lock.

3.
A problem with the interlock cable from the gear selector to the lock cylinder. Make sure you are completely in park.
You pretty much have to take things apart and visually inspect it to verify this problem.

4.
A mechanical problem with the linkage from the lock cylinder to the electrical part of the ignition switch.

If you cannot get the key to the RUN position you will have to drill it out i'm afraid !!
