What to do when engine problem

First try and detect the problem, is the car not starting, running roughly, conking out, or using too much petrol?

when the problem is found, isolate the system most likely to be its cause. If it is conking out, the fuel system may be at fault. If it is not starting, the electrical system may be worth looking at first. If the car is overheating, check the cooling system.

After you have isolated the most likely system, locate the weakest link in that system. The fuel pump, for example, is often the most vulnerable part of the fuel system.

Check each successive part in the system until the problem is solved.

Get the broken part replaced or repaired. Consult your car's manual for other specific problems you might be facing. This will help to speed up diagnosis, or you could send your car to the mechanics
