Important part of the system is spark plug both mixture of petrol & air. If these factors do not ensure the car will not start the engine.
Damage related to the ignition system
The engine turns but will not boot normally, the problem may belong to the ignition system, fuel or compression. You can check easily by connecting external spark plug wires or just act cool near the well.
If only a few spark plugs, ignition, electrical problems caused by the division or less elbow axis sensor. In case all the spark plug will not ignite, potty-bin may corrupt the ignition. Check coil resistance primary and secondary levels to know if this might be the cause.

Sometimes, no cause at any distance, only by a wire that was broken, loosely coupled to the voltage does not reach the spark plug. After trying to restart a few times, unplug and check the spark plug temperature. If they are hot, but the machine will not boot, it's time to find the cause in the fuel supply system. The most common damage is to work less efficient pump.The problems of fuel supply system
On engines using carburetors, fuel pumps not in the throat due to mechanical smoke less, stuck valve, fuel filter or clogged fuel line.
In newer cars use electronic fuel injection system. Use a pressure gauge to measure fuel pressure. If there is no pressure when the ignition key in ON mode, check the fuel pump, pump relays, fuses and wires. On Ford vehicles do not forget to check the safety switch hidden under the dashboard or trunk. This switch turns off the pump when the accident occurred. Therefore, you should check it and reset if necessary. Lack of fuel was due to blocked pipes or anti-shock devices in the tank. Do not forget to check the fuel level gauges. In some cases the car not start simply because out of fuel.
Poor fuel quality, contaminated water or too much alcohol also makes the machine will not boot.
Despite the pressure in the fuel supply system but not necessarily gas was injected into the combustion chamber. Using a stethoscope placed near the injector. Kim is the best spray emits sound during opening and closing. Otherwise, check the voltage placed on the injector. ECM can not control wrong nozzle, or the source of the EFI relay has stopped working.
One other important factor determining whether the motor can start or not is the rate of mixed gas / air. Gap on the manifold that the rate of fuel / air limit can reduce fire results in the machine can not boot. Please check all of openings in the pressure area after the throttle and vacuum sealing them.
Low mixture compression ratio
Provide enough fuel, good spark plug ignition, not without serious gaps in the manifold, normal crankshaft rotation, the engine still will not boot. The remaining problem related to compression ratio
With cam engines use rubber belts. The company OHC cam belt require replacement after 100,000 km of vehicle preventive maintenance activities. Many cam belt was never replaced until it breaks, the valves open and close the load is not the right time, compression ratio does not guarantee the combustion takes place. The engine will not start.
Cam can also be placed on top and stuck tight lid off if the bending is caused by intense heat, or lack of lubrication is prohibited. Cam might appear stuck in the cold start temperatures. Even in the low-te too thin to affect the camshaft.
With cam type chain that may arise or sliding off phenomenon. In this case, remove the protective cap and watch them work.
Check oil, water and if it detects them, rings shall probably have blown-up, the engine can not start.
