Car Won’t Start?
Don’t replace the starter or battery yet. Answer a few quick questions and see what should be checked first.
This tool does not diagnose your vehicle. It helps point out possible causes before guessing.
Do you hear a clicking noise?
A click, rapid clicking, or single click can point to battery, cable, ground, starter, relay, or control issues.
Does the engine crank but not start?
Cranking means the engine turns over, but it does not actually start and stay running.
Are the dash lights dim or flickering?
Dim lights, flickering lights, or lights going out when you try to start can point to low voltage or bad connections.
Did a jump start help?
If a jump start helped, the problem may be battery, charging system, cable connection, or something draining the battery.
Is there a security, key, or immobilizer light on?
Some vehicles will not start if the key, security system, immobilizer, or module communication has a problem.
Did it happen after a battery, jump start, or repair?
No-start problems can happen after low voltage, battery replacement, repairs, wiring work, programming, or module resets.
Don’t replace parts yet.
Based on your answers, here are the first things we should check before guessing at the starter, battery, or computer.
Important:
A no-start problem needs testing. A clicking noise does not automatically mean the starter is bad.
Final diagnosis may require battery testing, charging system testing, starter circuit testing, scan data, wiring checks, and security system checks.
