What does it mean when you start your car?
A car engine starts thanks to the ignition system. This is the unit that supplies the energy to get the motor going. The ignition system begins with a key, which you insert and turn, and ends with a spark that ignites combustion in the cylinders. This combustion is what starts the engine.

What do you say when your car won’t start?
When your car’s engine won’t start and all you hear is a rapid clicking noise, you’re likely to mutter, “Darn” (or perhaps another four-letter word) and instantly think that something is wrong with the battery. You would probably be right.
Why does my car not start when I Turn on the ignition?
When you turn the key in the ignition and the starter sends power from your battery to the engine it’s the spark plugs that use that power to ignite the fuel and air mixture in the combustion chamber. If your spark plugs aren’t working, then it doesn’t matter if you got a jump because the spark isn’t happening, and your engine won’t start.
Why does a car engine have to start at the right time?
The air intake and fuel valves must open at a precise time to supply fuel so it can be compressed and the spark plugs must fire right at the height of compression for optimum power. If they fire too slowly, the engine under-performs, and if they fire before the fuel is brought into the cylinder, the car may not start at all.

Why does my car take so long to start?
When your engine is warm and running normally it has lots of sensors to help determine the right ignition timing and fuel to keep it running smoothly. When your engine is first started, these sensors can’t help for a few seconds so the computer makes an educated guess at what the engine needs to run.
Why does my car turn over but won’t start?
If your engine will turn over but just won’t start you could have a few different problems. To start, your engine needs the right amount of fuel, a spark at the right time and air to mix with the fuel. Unless you’ve got an animal’s nest in your intake piping, it’s very unlikely that your engine isn’t getting enough air.
