Engine Won't Start: What to Check First
A car that won't start is one of the most common roadside problems — and most of the time, it comes down to one of three things.
The symptom
Key turns and nothing happens, or the engine cranks but won't catch.
What's causing it
Starting an engine needs three things: battery, fuel, and spark. Dim or no dashboard lights point to a weak battery. Cranking normally but not starting points to fuel or spark. Repeated clicking usually means the starter motor or battery.
What to do
Check in that order — cheapest first. If the battery checks out fine, the fuel vs. spark question needs a proper diagnostic rather than guesswork.
