Depending on the type of fuel system, a diesel engine may or may not use glow plugs. Glow plugs are generally used on Indirectly Injected diesel engines. They are used to heat the air that is drawn into the engine when the engine is cold. Since diesel engines use the heat created by compression to ignite the fuel/air charge, Glowplugs provide easier and smoother start ups. A Direct Injected diesel engine may use an Intake Air Heater or nothing at all, since the fuel being injected into the combustion chamber is atomized to a much finer degree (and therefor ignites at a lower temperature) than the relatively low injection pressure Indirect Injection system.
No , a diesel engine doesn't have sparkplugs It could have glow plugs
Unless your ford focus is a diesel your car does not have glow plugs.
glow plugs
Most unlikely. Glow plugs simply preheat to allow the engine to turn over from cold.
Possibly one or more bad glow plugs. try replacing your glow plugs.
If your car is a Diesel engine and when you turn the key on it ignites the glow plugs because diesel gas can congeal (become thick) in cold weather. So the glow plugs warm the diesel and turn it back to a more liquid state.
Possibly bad glow plugs.
The best answer is to follow the recommendations for maintenance in your particular car's owner's manual. A rule of thumb is every 30,000 miles for standard plugs and 60,000 for platinum or other precious metal plugs. Don't forget the ignition system's secondary wiring. Worn plugs and damaged wires can cause ignition coils and other ignition components to fail prematurely.

If only the ignition was on with no other appliances running you may be lucky. But the glow plugs in summer are not that critical. It could well be that there will be insufficient power to turn the engine over
the bmw 320d is a diesel car therefore it does not have spark plugs as it uses pressure to ignite the fuel rather than a spark it does however have glow plugs which function to heat the engine internally when starting and will show up on the dashboard display as a spring like symbol if they need changing ie the light does not go out after the car starts rather it stays lit while driving then you need to change them
check the battery, and make sure it is in park
