Symptoms are where every car problem starts — you feel, hear or smell something before any code or diagnosis exists.
This page works from what you’re experiencing toward the most likely causes, in the order a careful mechanic would check them, with explicit guidance on when to stop driving.
Possible causes
Weak battery — lights need little power, cranking needs a lot (most common)
Corroded terminals or bad ground straps
Failing starter motor or solenoid (single click)
Neutral safety switch or clutch interlock
Immobilizer/security lockout (check for a flashing key icon)
What to check first
Try starting in Neutral and jiggle the shifter — interlock faults are free to test
Check for a security/key warning flashing on the dash
Inspect and wiggle battery terminals; corrosion fails under load
