What is a car won’t start diagnostic?

There are few things more frustrating than when your vehicle refuses to fire into life when you turn the key. Sadly, this is likely to happen at some point to everyone and usually at the most inconvenient time.

ClickMechanic can come to the rescue though with a network of mechanics across the UK, usually within a short notice period to come out and diagnose the reason.

Please note, whilst we offer a short notice period on this service, we are not providing a roadside rescue type service and the mechanics may not be able to get to you on the same day.

What happens during a car won't start diagnostic?

In most cases, the cause is either the starter motor or the battery that is at fault, both of which can be resolved relatively quickly.

If you notice a rapid clicking, but the engine not turning over (or turning over very slowly), it is likely to be the battery at fault. If you get a single click and the engine not turning over, that is likely to mean it is the starter motor.

If the engine is turning over fine, but not starting, then further diagnostics will be required.

Therefore, the mechanic will need to access vehicles electronic control units (ECU) via the OBD port inside the vehicle. Please be aware that on some vehicles these are in covered areas such as under the ashtray, at the back of a storage hole or even in the glove box, so the mechanic will need to remove anything that is blocking access to it.

  • The mechanic will go through the diagnostic error code and read live data to pinpoint the cause(s) of the issue.
  • Mechanic will physically examine the vehicle’s powertrain for potential faults, such as intake air leaks, boost hose leak etc
  • If the cause of the issue requires additional work and parts, the mechanic will provide you with a quotation and a detailed description of the fault(s)
