If your dashboard lights up but your engine won’t crank, you’re not alone—knowing how to fix a car that won’t start but has power is one of the most searched DIY car questions today. It’s frustrating, confusing, and often happens at the worst possible moment.
This issue is usually a sign that your battery is fine, but something in the starting system—or beyond—isn’t doing its job. Before you pay a mechanic, here’s how to diagnose and possibly fix the problem yourself.
What Does “Has Power but Won’t Start” Really Mean?
You turn the key (or push the button) and the interior lights, radio, and dashboard come on—but the engine doesn’t even try to start. This means:
- The battery isn’t dead, but…
- The starter, ignition system, neutral safety switch, or key fob system might be the issue
Quick Fixes to Try First
✅ Check the Gear
Make sure the car is in Park or Neutral. A bad shift sensor or misaligned shifter can block ignition.
✅ Press the Brake or Clutch
Most push-to-start cars require full brake or clutch depression. Sounds simple, but it’s often overlooked.
✅ Wiggle the Steering Wheel
If your steering wheel is locked, it can prevent the ignition switch from turning fully.
✅ Jump the Starter Relay
If you hear a click but no crank, the starter relay or solenoid may be stuck—try swapping it with another relay temporarily.
Digging Deeper: What Might Be Broken?
🔧 Bad Starter Motor
- Symptoms: One loud click or repeated clicking but no crank
- Test: Tap the starter with a wrench while someone turns the key. If it starts—starter is failing.
🔧 Faulty Ignition Switch
- Symptoms: No dash lights when you turn the key; accessories may work
- Test: Turn key slowly—if power flickers, the switch is worn out
🔧 Dead Key Fob or Immobilizer Issue
- Symptoms: Car acts totally unresponsive to the push-button
- Fix: Try holding the key fob against the button (some cars have hidden override locations)
🔧 Blown Fuse or Relay
- Check the starter, ignition, and ECU fuses in both the under-hood and cabin fuse boxes

This problem is rarely the sign of total engine failure. Most of the time, it’s an affordable electrical or starter system issue you can diagnose yourself or fix for under $100.
When to Call a Mechanic
If you’ve tried everything above and the car still won’t start, it’s time to:
- Run a battery load test even if it has power
- Scan for error codes using an OBD-II scanner
- Have a tech check the starter circuit voltage drop
Final Thoughts
Knowing how to fix a car that won’t start but has power can save you time, money, and frustration. Whether it’s a stuck relay, bad starter, or faulty switch, the sooner you troubleshoot, the faster you’ll be back on the road—without wasting cash on guesswork.
