Car Won't Start in Bath? Here's What It Could Be
The three most common reasons a car won't start, and how a mobile mechanic tells them apart fast.
A car that won't start is one of the most common calls we get across Bath, and the cause usually falls into one of a small handful of categories. Working out which one you're dealing with before calling for help can save time — here's how to read the signs.
What kind of 'won't start' is it?
- Nothing happens at all — no lights, no sound
- A single dry click, then silence
- Rapid repeated clicking from under the bonnet
- The engine cranks over but never actually fires
- Dashboard lights come on but the starter doesn't engage
Most likely causes
- A flat or failing battery — the most common cause by far
- A faulty starter motor or solenoid
- A blown fuse or relay in the starting circuit
- An immobiliser or key fob fault preventing the engine from firing
- A fuel or ignition fault if the engine cranks but won't fire
How we diagnose it
We start with the cheapest, most likely cause first — battery voltage and connections — before moving on to the starter motor, relays and finally fuel or ignition systems if the engine is cranking but not firing. This order gets most cars diagnosed within 20-30 minutes.
What to do next
If your car won't start at home, don't repeatedly try the key — this can drain the battery further or flood the engine. A call to a mobile mechanic will usually resolve it on the spot without needing recovery to a garage.
Frequently asked questions
A single dry click almost always points to a weak or dead battery not delivering enough current to the starter.
