Why does my AU motor not start when cold?
Then, the AU motor is controlled by an ECU (engine management computer) and has lots of sensors (temp, atmospheric pressure etc) which the computer reads to determine amount of petrol etc to use to start the motor. If your temperature sensor is stuck on say 20 degrees, it will not supply enough petrol to start well when cold.
What causes a car to not start the next day?
The lack of oil will cause engine components to rub and cause friction. This creates heat, and in extreme cases, the heat can cause parts to weld together in inappropriate places in your car. If your car won’t start, then it starts the next day, which can sign a failing ignition switch.
Why does my Falcon AU-Ford engine not start?
It has an intermittent starting problem. When the ambient weather is low (below 15 deg C or so – having been parked overnight) it does not start. The engine cranks – but doesn’t start. It allows me to crank it 3 times, after which, nothing happens when I turn the key.
What does it mean when your car cranks but won’t start?
Some car owners think that it means that the engine is running. To a technician, it just means that the starter is successfully engaging the flywheel and rotating the engine’s crankshaft. Some technicians will interchange this with the word “cranking.”
Where is the starter on a car that won’t start?
To figure out why your car won’t start, it helps to know the difference between the starter and the ignition switch. The starter is an electric motor that cranks the engine, effectively starting the car. It is under the hood, usually on the passenger side at the bottom of the motor next to the transmission.

Why does my car not start after I drain the battery?
A broken timing belt, timing chain or timing gear means you can crank the engine until you drain the battery, and it still won’t start. Likewise, a bad crankshaft position sensor won’t send the right signals to the engine computer to allow the engine to start. 8. Smart Key Issue
