How to Start a Car with a Bad Starter

When your vehicle’s starter motor fails, it’s crucial to know alternative methods to get your engine running. Here are the two most reliable techniques: jump-starting your car and push-starting your vehicle. Both methods can help you temporarily bypass a faulty starter, but each has specific requirements and safety considerations.

Jump-Starting Your Car

Often, a dead or weak battery is the culprit preventing the starter from functioning properly. Providing the starter with a surge of electrical current can sometimes kick-start the engine. This process involves using jumper cables and a working vehicle or a portable jump starter. Here’s a detailed procedure:

Open your car’s hood and locate the battery. Refer to your vehicle’s manual if you’re unsure about its placement. Avoid working on a battery that appears bloated, leaking, or damaged—call a mechanic instead.
Connect the positive (red) jumper cable to the positive terminal of your dead battery, then attach the other end to the positive terminal of the operational battery or jump starter.
Attach the negative (black) jumper cable to the negative terminal of the good battery and connect the other end to an unpainted metal surface on your vehicle’s engine block or chassis—away from the battery itself.
Start the donor vehicle or turn on the jump starter, then attempt to start your vehicle. Allow a few minutes for the battery to charge and the starter to respond.
Once your engine is running, carefully disconnect the jumper cables in reverse order: remove the negative cable first, then the positive.

Note: If your battery is healthy but the engine still doesn’t start, the issue may lie within the starter itself or related components like the starter relay.

Push-Starting the Vehicle

Push-starting, also known as bump-starting, is an effective method for vehicles with manual transmissions. It is less suitable for automatic transmissions due to safety and mechanical reasons. Here’s how to execute a push-start:

Keep the engine running and shift into second gear to ensure smoother engagement and reduce stress on the transmission.
Find a clear, flat stretch of road and have a few strong individuals push the vehicle from behind to gain momentum—aim for about 5-10 mph.
Once the vehicle reaches the desired speed, quickly release the clutch pedal while simultaneously engaging the ignition to start the engine.
If the engine doesn’t turn over on the first attempt, try again after stopping briefly to reset the process.

Remember, push-starting is only feasible with manual transmissions and should be performed cautiously to avoid accidents or damage.

Recognizing Symptoms of a Failing Starter

Identifying early signs of a malfunctioning starter can prevent complete breakdowns. Common symptoms include:

Engine does not crank: When turning the key or pressing the start button, there’s no response, indicating the starter may be failing.
Unusual noises: Grinding, whining, or clicking sounds when attempting to start the vehicle could point to worn gears or electrical issues within the starter.
Smoke or burning smell: Overheating of the starter due to electrical faults can cause smoke or a burnt odor under the hood.
Intermittent starting problems: If your car starts inconsistently, especially after multiple attempts, the starter relay or connections might be compromised.

How to Diagnose a Faulty Starter

Proper diagnosis ensures accurate repairs. Follow these steps:

Check the Electrical Connections

Inspect the battery cables and terminals for corrosion, looseness, or damage. Ensure the positive cable is securely attached to both the battery and starter. Tighten any loose connections and clean corrosion with a wire brush.

Examine the Starter Solenoid Cable

The solenoid acts as a switch that engages the starter motor. Check for dirt, rust, or damage on the solenoid wire. If needed, bypass the solenoid by connecting a 12V cable directly from the battery to the starter to test whether it engages smoothly. Listen for a clicking sound indicating activation.

Test the Battery Voltage

Use a multimeter set to 20V to measure your battery’s voltage. Connect the leads to the battery terminals. A healthy battery should read between 12.7V and 13.2V. If the voltage drops below 12.4V, recharge or replace the battery before further testing.

Inspect the Engine Flywheel

Remove the engine cover or transmission components to access the flywheel. Manually turn the crankshaft using a ratchet or breaker bar. Look for damaged or missing teeth on the flywheel’s ring gear, which could prevent proper engagement with the starter gear.

Check Engine Grounds

Ensure the ground wires from the engine and transmission are free of rust and securely attached. A poor ground connection can inhibit the starter’s operation. For a quick test, attach a jumper cable from the negative battery terminal directly to the starter’s frame and attempt to start the engine.

Tap the Starter

If the starter occasionally fails to engage, gently tapping it with a hammer can sometimes free stuck parts or dead spots in the motor. Proceed with caution to avoid damage.

Inspect for Corrosion

Corrosion on battery terminals, cables, or the starter itself can impair electrical flow. Clean all connections thoroughly and replace any corroded parts to restore proper function.

Starting a Car with a Faulty Ignition Switch

If your ignition switch is defective, traditional starting methods may not work. Two alternative approaches include hotwiring and jump-starting:

Hotwiring a Car with a Bad Ignition Switch

Note: Hotwiring is generally applicable for older vehicles manufactured before the mid-1990s. Proceed with caution and only on your own vehicle. Here are the steps:

Remove the panels covering the steering column to access the ignition wiring.
Identify the wires connected to the ignition switch—usually a set of color-coded wires.
Using a screwdriver or a similar tool, connect the positive (+) terminal wire to the wire leading to the starter solenoid.
Join the ground wire to a metal part of the vehicle chassis.
Once connected correctly, turn the key or manually close the circuit to start the engine.

Remember, hotwiring can be risky and may damage your vehicle’s electrical system; consult a professional if unsure.
