Fix It

Open the Quests front door. Adjust the drivers seat as far back as it will go in order to provide yourself with sufficient room to access the under-dash area.

Shine the work light in the drivers foot well so it illuminates the area at the top of the brake pedal arm. Retract the retaining tab on the brake light wiring pigtail with your thumb while gripping the pigtail with your foinger. Pull the pigtail off the brake light switch.

Unbolt the faulty brake light switch from the mounting bracket using a box wrench. Discard the faulty brake light switch.

Set the new brake light switch into the bracket. Bolt it in with the box wrench. Plug the wiring pigtail into the new brake light switch by hand.

Depress the brake pedal and have your helper verify the brake lights work before driving your Nissan Quest.

Insert your key into the E320s ignition and turn it. Listen for a "clicking" noise. If you hear the clicking noise, you will need to have the car towed to a garage to have the alternator replaced.

Look at the fuel gauge while the key is in the ignition. Add gas to the car if needed and then try to start the E320.

Open the E320s trunk and locate the battery. Make sure that the battery terminals are connected to the battery properly. You can tell this by the "+" and "-" signs on the terminals and the connecting wires.

Connect jumper wires to the "+" and "-" terminals on your battery and then connect the other end of the jumper wires to a different car battery. Start the other car with the wires connected and then try to start your car.

Leave the E320 running for about 15 minutes to allow the battery to charge. Turn the E320 off and wait for a couple of minutes. Start the E320 again. If the car will not start, you need to replace the battery.

Start the engine and let the 1993 DeVille warm up. On some GM cars, including the Cadillac line, once the engine has warmed up, the gearshift may be operable. Also, check to ensure the brake pedal is working by pressing down on it. If warming up the car doesnt resolve the problem, go on to the next step.

Manually trip the brake shift interlock solenoid. Start the car. Lift the rubber panel cover under the ashtray and open the under-dash compartment door.

Shine a flashlight into the under-dash compartment and look for an orange lever tab. Push orange lever tab toward the hood of the DeVille to override the automatic lock manually. Listen for a click that indicates the solenoid has been released.

Depress the brake pedal again and attempt to shift the Cadillac into gear.

Open the hood to the Suburban and look over the battery connections. These should not have any corrosion or debris on them.

Remove the corrosion on your Suburban with soda and a wire brush.

Put the terminals back onto the battery and then tighten them with a socket wrench.

Try to restart the car.

Jump start the Suburban with another car and jumper cables.

Leave the car running for about 5 minutes and then turn it off.

Try to restart the SUV. If the SUV does not restart, replace the battery.

Check the fuel levels to the car. Add one gallon of gas to the car and then try to start it again. If the SUV starts, replace the gas gauge.

Add 1 gallon of gas to your C230 and then turn the key in the ignition on and off a couple of times while you are pumping the C230s gas pedal. This will engage the cars fuel pump.

Turn the ignition and listen for a clicking noise. Have a mechanic check the starter if you hear a clicking noise

Turn the ignition over without starting the car. Check the electrical lights in your cars dashboard. If the lights do not come on or the lights are really dim, the battery needs to be charged or replaced.

Jump start the C230 with another car and a pair of jumper cables. Allow the car to run for about 5 minutes and then turn it off. Try to restart the car. If the car will not turn back on, you need to replace the battery.

Examine the spark plug wires and the connections between the plug wires, the spark plugs and the coil. If the plug wires are cracked, frayed or visibly corroded they must be replaced. If any connection is loose push it back together with your fingers.

Remove the front and back spark plugs with a socket wrench and a spark plug socket. Remove each spark plug by turning it counterclockwise and look for visible signs of fouling. The electrodes should be light tan or gray and intact. Replace if fouled.

Remove the plug wire leads from the coil electrodes. Look for corrosion on the coil electrodes. Remove any corrosion with a wire brush.

Remove the seat bolt from the back of your seat. Pull the seat back off to access the battery. Your battery is dead if the solenoid chatters when you try to start the bike. If the battery is dead, then connect the positive and negative leads from a motorcycle battery charger to the same terminals on your battery.

Charge the battery for four hours. Attempt to restart the Ultra Classic.

Examine the battery terminals and cables for signs of corrosion. Remove any corrosion with a wire brush. Replace the battery if it will not charge or if a terminal is broken.

Troubleshoot your carburetor. Remove the air cleaner cover by unscrewing the Allen bolt or bolts securing it to the air cleaner.

Loosen the air cleaner by removing the three or four Torx bolts that secure the air cleaner to the backing plate. Hold the air cleaner in your less dominant hand while you disconnect the breather tubes from the top of the air cleaner with a box wrench.

Remove the air cleaner backing plate. Examine both throttle cables. Ensure they are both attached to the throttle cam.

Access the fuel air adjustment screw on the bottom of the carburetor. Gently turn the adjustment screw clockwise with a small, flat-head screwdriver until it is fully closed. Turn the adjustment screw counterclockwise 2-1/8 turns. Attempt to start the motorcycle again.
