You are going to have to drain the tank and flush everything out! If it has been turned over and taken the DEF fluid into the fuel system then you will need to crack the injector lines loose and run clean fuel through them then bleed all the air from the lines before starting it! DEF fluid is very corrosive and could damage the injectors and injector pump if not taken care of in a quick manner!

Charge the battery. Even though your indicator shows that it is charged it may have gone bad, a lot of batteries will show a full charge but fail when a load is put on them, so your battery may have gone bad! Harbor Freight sells a battery tester that is pretty cheap but does the job, it places a load on the battery and shows you the true condition!

unless it was made with that arrangement it will not tilt
in that case you will have to install a later model column that tilts

It is possible dedicated diagnostic software is needed to restore default values after replacing the throttle sensor.
Just a guess...

My first guess is you have a burned out bulb. The fast flash of the ones that do work is usually an indication of this. Check the bulbs in the units that don't work.

Something wrong with the shift lock system maybe. Safety system that won't allow the gear selector to move from park unless the driver is pushing the brake pedal . Do your brake light's work ? Does your caddy have floor or column shift ?
Automatic Transmission Shift Lock Control Description and Operation (Floor Shift)
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM).The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage supply circuit of the shift lock control solenoid. The following conditions must be before the BCM will supply voltage to the shift lock control solenoid.
The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will supply voltage to the shift lock solenoid:
• The ignition is in the ON position.
• The ECM sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
• The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically unlocking the shift lever allowing the driver to move the shift lever out of the PARK position as the solenoid energizes. When the brake pedal is not applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid mechanically locks the shift lever in the PARK position.
During remote start operation, the BCM will de-energize the shift lock control circuit, locking the shift lever in the PARK position.

More then likely a problem with the shift interlock system . Stepping on the brake pedal , do the brake light's light up ? The shift interlock system is a safety system that won't allow the gear selector to be moved out of park unless driver is pushing the brake pedal . Part's involved - brake switch , inlock solenoid , wiring etc.... May also have electronic module involved , BCM - body control module .
Do you have floor or column shifter ?

Shift Interlock System
The shift interlock system consists of:
  • a shift lock actuator .
    • A transmission shift lock actuator, which clips to the actuator retainer, securing the shift lock actuator to the steering column.
    • A transmission shift lock actuator cable which routes to the floor console mounted shifter assembly lock mechanism.
  • electrical circuits to supply power to lock and unlock the shift lock actuator.
The shift lock mechanism locks the gearshift lever in PARK:
  • when the ignition switch lock cylinder is in the LOCK position.
  • with the ignition switch lock cylinder in the RUN position and the brake pedal released.
The shift lock actuator releases the gearshift lever:
  • when the ignition switch lock cylinder is in the FIRST position.
  • with the ignition switch lock cylinder in the RUN position and the brake pedal actuated.

Does it have an immobilizer? Has it started since the battery was swapped out?
