1. The terminals on the battery as one may be loose
   Whether it has gas or not
2. The sparkplugs
   The carburetor

An engine that is totally dead and won't turn over could have a number of causes. The first thing to check is that the terminals are connected to the battery. You won't believe how easily these can actually come off.

1. Put in more gasoline
   Stop the car and check the oil level. Put in oil if necessary
2. Check the coolant level in the car
   Check the brake fluid level

That light should not be ignored! If it starts to glow, check your oil immediately. If the oil in your engine is too low, it can cause massive damage.

1. Your engine is on fire, put it out!
   You don't need to fix it. This means your engine is running clean.
2. Generally, when this happens when the head gasket no longer makes a seal.
   Check the oil level

The head gasket is no longer making a seal and this is probably as a result of a cracked engine block.

1. Add oil
   Add coolant to the radiator
2. Add gasoline
   Check your battery

The battery is not taking charge and either a cell is dead or your car's alternator is not working properly.

1. Spark plugs
   The distributor
2. Oil level
   Coolant level

Fouled up spark plugs will not fire properly. This can certainly lead to your engine misfiring. In fact, it's a good idea to clean them regularly.

1. Oil filter
   Fuel filter
2. Crankshaft
   Fan belt or other belts

A wearing belt, which is generally easy to spot as it would have frayed, can be replaced fairly simply. That will solve your squeaking problem.

1. Distributor cap
   Alternator
2. Hi-tension leads
   Engine block

The alternator helps keep your battery charged. If it is not working, the battery will slowly drain of power. A dead alternator will eventually mean a car that is going nowhere. Luckily, they are fairly easy to replace.

1. Check the coolant level in your radiator. It is probably leaking
   Check the brake fluid levels
2. Check that your oil or fuel filter is not leaking
   Don't check anything, it's nothing to worry about

A leaking radiator is a massive problem. If not fixed, coolant levels will drop, your engine will overheat and could seize. A quick fix is to use a radiator sealant, but ultimately, it will need to be replaced.

1. If the wheel nuts are still tight
   The tire tread
2. The rims
   The brake pads. Sounds like they are worn.

Worn brake pads are dangerous! As soon as your brakes begin to squeal or shudder under normal braking, the brake pads should be checked and replaced if necessary.

1. Check the oil level
   You are running out of gas
2. Your car's engine is overheating
   It's not serious, ignore it

An overheating engine is no joke. If the radiator has no leaks and you cannot see coolant on the ground once the car has been standing, then the problem could like with the thermostat. This helps to regulate the engine temperature and if broken, can make the engine overheat.

1. The fuel/air mixture. The car engine is running too rich.
   Make sure the engine is not on fire
2. The catalytic converter
   None of the above

If an engine is running too rich, too much gas is been pumped into it, and it cannot be burned effectively. Not only are you wasting money but it means the engine is not running at the optimal level either.

1. Your carburetor is faulty
   Your battery is faulty
2. Your have flooded the engine with gasoline
   It's cold, so the car won't start

A flooded engine simply will not start. This is because the gas/air mixture is too rich. There is too much gasoline for combustion to take place. Wait 20 minutes an try again but do not press the accelerator when starting the car.

1. Green
   Brown
2. Blue
   Purple

Most oil although black when new, will go a browning color once cycled through the engine as a lubricant.

1. Flat wheel
   A broken motor mount
2. Faulty air filter
   None of the above

Because the driver holds a steering wheel, effectively steading themselves, some vibration are not felt as much as they would be in the passenger seat. An intense vibration felt while sitting there is in all likelihood a broken motor mount.

1. Stop your car and call a mechanic.
   You need gas.
2. You need to check your oil.
   Don't worry about it, if it was a problem it would be red, not yellow.

The engine warning light can indicate a small problem or it could indicate a big problem. It's better to get it checked out as soon as possible.

1. The oil filter
   The sump
2. The carburetor
   Sparkplugs

A problem with the fuel/air mixture could mean that the engine runs poorly. The carburetor regulates this and should be the first thing you check.

1. Sump
   Crankshaft
2. Pistons
   Distributor cap

A spark is needed for the engine to turnover as this helps ignite the fuel/air mixture. The broken distributor means that the spark won't happen.

1. Glow plugs
   Spark plugs
2. Stater motor
   None of the above

If the battery is ok, the next thing to check is the starter motor. If the engine won't turn over, it may be jammed.

1. Faulty spark plug
   Faulty glow plug
2. Lack of diesel
   None of the above

Diesel engines are very different to petrol engines. Glow plugs help heat the motor to help it start. If they are faulty, starting might prove difficult.

1. The engine is about to seize.
   You are running out of coolant.
2. The radiator is leaking.
   None of the above

This is a SERIOUS problem. Stop the car before anymore damage is done, call a mechanic and hope the engine can be saved.

1. Pump up the tire, that will do it.
   Your rims are failing. Get new ones.
2. It could be a loose wheel nut. Check they are all tightened.
   None of the above

Believe it or not, sometimes wheel nuts do come loose. Make sure you check them regularly.

1. The fuel filter
   The oil filter
2. Hi-tension wires
   The muffler

Mufflers suffer wear and tear doing their job of keeping your car quiet. If they get a hole in them, they no longer do their muffling, hence a louder engine noise as the gases escape down the tailpipe.

1. It's an ignition coil that needs to be replaced.
   Stop using higher octane fuel.
2. You have an oil leak, fix it.
   None of the above

Yes, a faulty ignition coil can cause a car to run, even though it has been switched off and the key removed. No, it's not the previous owner's ghost.

1. Not enough gas
   The gas filter was clogged
2. Spark plugs broke
   Not enough oil for lubrication

It's that simple. A car engine uses oil for lubrication. If there isn't enough, thanks to an oil leak perhaps, the engine will seize. Sadly, there is no quick fix and hopefully it was noticed in time.

1. Check oil light
   Brake warning light
2. Catalytic converter failure
   None of the above

Fairly serious as your brakes stop you, don't they? It may be a problem with the hydraulic system.

1. The car heater
   The water pump
2. The cabin air filter
   None of the above

The cabin air filter is found in the glove box in most vehicles. It helps clean the air coming into the cabin but can be clogged up with all sorts of nasties and then will start failing in its primary task. It is easy to replace.

1. Sparkplugs
   Gas injection system
2. High tension leads
   Oil filter

As the new oil will flow through the oil filter, it too will need to be replaced to ensure the new oil stays clean and effective at lubricating the engine.

1. ABS braking system
   Traction control
2. Check for an oil leak
   Check for the transmission fluid

Not all cars have traction control. This system is great in keeping your car on the road but make sure you check it out when this warning light comes on.

1. Pump up the tire
   Check the engine mountings
2. Change the tires
   Replace the wheel bearings

A whirring or rumbling sound that increases as you speed up is a classic case of a worn wheel bearing. You will need to have it replaced.

1. Fuel filter
   Oil sump
2. Catalytic converter
   None of the above

A smell of rotten eggs is generally a sign that your catalytic converter is failing. It cannot convert the exhaust gases into sulfur dioxide.

1. Alternator
   Starter motor
2. Carburetor
   Distributor cap

The easiest explanation for fading lights is the fact that your battery is not been charged as the alternator is not working properly.

1. It is not a radial tire.
   It is overinflated.
2. Your wheel alignment is out.
   It needs a new inner tube.

It is imperative to have your car's wheel alignment checked often. The slightest knock can put it out and that will lead to tires wearing unevenly.

1. The honeycomb mess within the catalytic converter has come loose
   Worn tires
2. Your rims need replacing
   None of the above

Part of the cleaning system on the catalytic converter is a honeycomb cluster. This often breaks free from the housing of the converter and will then rattle. Replace the converter to fix this problem.

1. Sump
   Fuel pump
2. Crankshaft
   Pistons

A car needs fuel to start, it's part of the ignition process. If a fuel pump has failed, it will not be pushing fuel into the ignition system and the car won't start.

1. Starter motor
   Pistons
2. Spark plugs
   None of the above

If there is a fault within the starter motor, it can often drain power during the startup process. That would cause the interior lights to dim. Replace it before it becomes something more serious!
