Why Your 2013 Traverse Won’t Start Even After a Jump Start

There’s nothing quite as frustrating as hopping into your 2013 Chevy Traverse, turning the key, and hearing… nothing. Or worse—after a jump start, the engine cranks but still refuses to fire up. You’ve tried the cables, double-checked the connections, and even waited a few minutes, but the result is the same. If you’re nodding along, you’re not alone. This issue is more common than you might think, and it can leave even seasoned drivers scratching their heads.

As someone who’s spent years diagnosing car problems (and occasionally falling victim to them), I’ve learned that a jump start working but the vehicle still not starting is rarely just a “bad battery.” It’s a clue—a breadcrumb leading to a deeper electrical or mechanical issue. Whether you’re stranded in a parking lot, at home, or in a hurry to get somewhere important, understanding what’s really going on under the hood can save you time, money, and a lot of stress. In this guide, we’ll walk through the most common reasons your 2013 Traverse won’t start even after a jump, how to diagnose them, and what you can do to fix the problem—without needing to call a mechanic every time.

Understanding the Jump Start: When It Works but the Car Still Won’t Start

Let’s start with the basics. A jump start delivers a burst of power to your battery from another vehicle or a portable jump starter. If your engine cranks—meaning the starter motor spins—then the jump is working. But if the car still doesn’t start, the problem isn’t lack of power; it’s something else preventing the engine from firing up. Think of it like a campfire: you’ve got the kindling (the battery), the match (the jump), but if there’s no fuel, oxygen, or spark, the fire won’t catch.

Jump Start Working but No Start: What It Really Means

If your 2013 Traverse cranks after a jump but won’t start, the battery and alternator aren’t the primary culprits—at least not directly. The jump has already bypassed a weak or dead battery. So what’s left? The engine needs three things to run: fuel, spark, and air. If any of these are missing or disrupted, the engine won’t start—even with a strong cranking signal.

Here’s a real-world example: A friend of mine had this exact issue. He jumped his Traverse, the engine cranked strongly, but it wouldn’t fire. After a few minutes of frustration, he noticed the fuel gauge was on empty. He added 2 gallons of gas, and the car started right up. The battery wasn’t the problem—the fuel pump wasn’t getting enough pressure because the tank was dry. A simple fix, but one that’s easy to overlook when you’re focused on the electrical system.

Common Misconceptions About Jump Starting

Many people assume that if a jump start makes the lights and radio come on, the battery is fine. But that’s not always true. A battery can power accessories but still be too weak to support the full starting sequence. However, in the case of a successful jump—meaning the engine cranks—you can rule out a completely dead battery. The real issue is likely one of the following:

• The battery is old and can’t hold a charge, even after a jump
• The alternator isn’t recharging the battery properly
• Fuel delivery issues (pump, filter, pressure)
• Ignition problems (spark plugs, coils, ignition module)
• Electrical glitches (faulty sensors, bad grounds)
• Security system interference (passkey system, immobilizer)

Don’t fall into the trap of blaming the battery every time. Use the jump as a diagnostic tool: if it cranks, the battery isn’t the root cause—it’s a symptom of a larger issue.

Top Electrical Issues That Prevent Your 2013 Traverse from Starting

Since your jump start is working, we’re focusing on electrical components beyond the battery. The 2013 Traverse uses a complex electrical system with multiple sensors, modules, and circuits. A single failure in any of these can disrupt the starting process, even with ample power.

1. Bad Alternator: The Silent Killer

The alternator is responsible for charging the battery while the engine runs. If it’s failing, the battery won’t stay charged—even after a jump. You might start the car once, but after turning it off, it won’t start again. This is a classic sign of alternator trouble.

How to check: After jump-starting the Traverse, let it run for 10–15 minutes. Then turn it off and try to restart it without jumping. If it won’t start, the alternator likely isn’t recharging the battery. You can also use a multimeter to test the battery voltage while the engine is running. A healthy alternator should show 13.5–14.5 volts. If it’s below 13, the alternator is underperforming.

Pro tip: Listen for a whining or grinding noise from the engine bay. A failing alternator often makes unusual sounds before it dies completely.

2. Faulty Starter Motor or Solenoid

Even if the engine cranks, the starter motor or its solenoid (the switch that engages the starter) might not be functioning properly. A weak starter can crank the engine slowly or intermittently, making it hard to start—especially in cold weather.

Signs of a bad starter:

• Clicking noise when you turn the key (solenoid is working, but motor isn’t)
• Grinding or whining sounds during cranking
• Engine cranks slowly or stops mid-crank

Try tapping the starter lightly with a wrench (while someone else tries to start the car). Sometimes, a worn starter will engage after a jolt. This isn’t a fix, but it can confirm the diagnosis.

3. Bad Ground Connections or Corroded Wiring

Ground wires connect the battery and engine to the vehicle’s frame. If these connections are corroded, loose, or damaged, the electrical system can’t complete the circuit—even with a jump. The 2013 Traverse has several ground points, including near the battery, engine block, and transmission.

How to check: Visually inspect the battery terminals and ground cables. Look for white or green corrosion, frayed wires, or loose bolts. Clean the terminals with a wire brush and tighten all connections. You can also use a multimeter to test resistance between the battery negative terminal and the engine block—there should be near-zero resistance.

Real-life example: A reader once told me his Traverse wouldn’t start after a jump. He cleaned the battery terminals and tightened the ground wire to the engine. The car started on the first try. Simple fix, but easy to miss.

4. Ignition Switch or Key Fob Issues

The 2013 Traverse uses a push-button start or keyed ignition with an anti-theft system (Passkey). If the ignition switch is failing or the key fob isn’t communicating with the car, the engine won’t start—even if it cranks.

What to do:

• Try a spare key or fob. Sometimes the battery in the fob is weak, and the car doesn’t recognize it.
• Check the dashboard for a “No Key Detected” or “Security” light.
• If the car cranks but won’t start, and you see a security light, the immobilizer system may be blocking the start.

Some owners report that leaving the key in the “on” position for 10 seconds before cranking can help reset the system. It’s worth a try if you’re stuck.

Fuel and Ignition System Failures: The Hidden Culprits

Even with a strong electrical system, your 2013 Traverse won’t start without proper fuel delivery and spark. These systems work in tandem, and a failure in either can leave you stranded—especially after a jump.

1. Fuel Pump or Fuel Pressure Problems

The fuel pump sends gasoline from the tank to the engine at high pressure. If it’s failing, the engine won’t get enough fuel to ignite. A weak pump might work when the tank is full but fail when the fuel level drops.

How to diagnose: Turn the key to the “on” position (without cranking) and listen for a hum from the rear of the car (near the fuel tank). This is the fuel pump priming. If you don’t hear it, the pump might be dead or the relay is faulty. You can also use a fuel pressure gauge to test pressure at the fuel rail. Normal pressure should be 55–62 psi.

Tip: If the pump is dead, you’ll need a professional to replace it—the tank has to be dropped. But if it’s just a clogged filter, that’s a simpler fix.

2. Clogged Fuel Filter

The 2013 Traverse has an in-tank fuel filter, which is rarely replaced unless there’s a problem. Over time, dirt, rust, and debris can clog the filter, restricting fuel flow.

Symptoms:

• Hard starting, especially after sitting overnight
• Engine sputters or stalls at low speeds
• Loss of power under load

While not a common cause of complete no-start, a severely clogged filter can prevent the engine from firing—even with a jump. Replacing it is a job for a mechanic, but it’s worth considering if you’ve ruled out other issues.

3. Ignition Coils or Spark Plugs

The spark plugs ignite the fuel-air mixture in the cylinders. If the plugs are worn or the ignition coils are failing, there’s no spark—and no start.

Signs of trouble:

• Engine cranks but won’t fire
• Rough idle or misfires when running
• Check Engine Light with codes like P0300 (random misfire)

The 2013 Traverse uses coil-on-plug (COP) ignition, where each plug has its own coil. A single bad coil won’t always prevent starting, but multiple failures will. Replacing spark plugs every 60,000–100,000 miles (as recommended by GM) can prevent this issue.

DIY tip: Swap a suspected bad coil with one from a working cylinder. If the misfire moves, you’ve found the culprit.

Sensor and Computer Glitches: When Electronics Betray You

Modern vehicles like the 2013 Traverse rely heavily on sensors and computer modules. A faulty sensor can send incorrect data to the engine control unit (ECU), preventing the engine from starting—even with a jump.

1. Crankshaft Position Sensor (CKP)

The CKP sensor tells the ECU when the crankshaft is rotating. Without this signal, the ECU won’t fire the spark plugs or inject fuel. A failed CKP sensor is a common cause of no-start conditions.

Symptoms:

• Engine cranks but won’t start
• No spark or fuel injection
• Intermittent stalling when running

Diagnosis: Use an OBD2 scanner to check for code P0335 (CKP sensor circuit malfunction). The sensor is located near the transmission bell housing and can be replaced in about an hour. It’s a common failure point in GM vehicles.

2. Camshaft Position Sensor (CMP)

The CMP sensor helps the ECU determine the position of the camshaft, which affects fuel injection timing. A bad CMP can prevent starting, especially in cold weather.

What to look for: Code P0340 (CMP sensor circuit) or P0341 (CMP sensor range/performance). The sensor is located on the front of the engine, near the timing cover. Replacement is straightforward but requires care not to damage the wiring harness.

3. ECU or BCM Communication Errors

The Engine Control Unit (ECU) and Body Control Module (BCM) communicate to allow the engine to start. If there’s a glitch in this communication—due to a software bug, water damage, or electrical interference—the car won’t start.

How to reset: Disconnect the battery for 10–15 minutes. This can reset the ECU and BCM. Reconnect and try starting. If it works, the glitch was temporary. If not, the issue is likely a hardware failure.

Note: Some owners report that driving through heavy rain or washing the engine bay can cause short-term ECU issues. Avoid spraying water directly on the fuse box or control modules.

Preventive Maintenance and Proactive Fixes

The best way to avoid a “2013 Traverse will not start jump start working” situation is to stay ahead of common failure points. Regular maintenance can prevent many of the issues we’ve discussed.

1. Battery and Charging System Check

Have your battery and alternator tested at least once a year—especially if your Traverse is over 5 years old. Many auto parts stores offer free testing. Replace the battery every 4–5 years, even if it seems fine. A weak battery can strain the alternator and starter.

2. Fuel System Care

Use high-quality fuel and add a fuel system cleaner every 10,000 miles. This helps prevent clogged injectors and filters. If you drive short distances or let the car sit for long periods, consider using a fuel stabilizer to prevent gum buildup.

3. Sensor and Ignition Maintenance

Replace spark plugs and ignition coils at the recommended intervals. Inspect wiring harnesses for damage, especially near the engine and transmission. A frayed wire can cause intermittent no-start issues.

4. Keep a Jump Starter and Diagnostic Tool

Carry a portable jump starter in your Traverse. It’s faster and safer than relying on another vehicle. Also, invest in an OBD2 scanner. It can read diagnostic codes and help you pinpoint problems before they leave you stranded.

Keep your maintenance up to date, and carry the right tools. With a little knowledge and patience, you can keep your Traverse running smoothly—and avoid that dreaded “no start” moment.

And if all else fails? Don’t hesitate to call a trusted mechanic. Sometimes, the best fix is knowing when to ask for help. But at least now, you’ll know exactly what to tell them.

Frequently Asked Questions

Why is my 2013 Traverse not starting even after a jump start?

If your 2013 Traverse won’t start despite a jump start, the issue could be a failing battery, corroded terminals, or a deeper electrical problem like a faulty alternator or starter. A jump start may provide temporary power, but underlying issues need diagnosis.

Can a bad alternator cause a 2013 Traverse not to start, even with a jump?

Yes, a malfunctioning alternator can prevent your 2013 Traverse from starting because it fails to recharge the battery while driving. Even with a jump start, the battery will quickly lose power if the alternator isn’t working properly.

What are common reasons a jump start doesn’t fix a 2013 Traverse not starting?

Common causes include a dead or damaged battery, corroded or loose battery cables, a faulty starter motor, or issues with the fuel system or ignition. A jump start bypasses only weak battery power, not these other mechanical or electrical faults.

How can I diagnose if the battery is the issue when my 2013 Traverse won’t start?

Check the battery voltage with a multimeter (should read ~12.6V when off). If it’s below 10V after a jump start, the battery likely needs replacement or has a dead cell. Also, inspect terminals for corrosion or looseness.

Is it safe to repeatedly jump start a 2013 Traverse that won’t start?

Repeated jump starts can damage the vehicle’s electrical system or battery. While occasional use is safe, persistent reliance on jump starts indicates a deeper issue that needs professional repair to avoid further damage.

What should I check if my 2013 Traverse cranks but won’t start after a jump?

If the engine cranks but doesn’t ignite, inspect the fuel system (e.g., fuel pump, filter), spark plugs, or ignition coils. A jump start won’t resolve these issues, which prevent fuel or spark delivery to the engine.
