Any number of problems with an engine can keep a car from starting up, making it one of the more difficult problems to solve, even for experienced mechanics. While some of these issues may be solved with a little mechanical know-how, or even a research on the Internet, many require the services of a qualified, professional auto mechanic.
The key for the driver is to remain calm and to approach the problem in a rational, methodical manner. Look for the easiest to detect and most likely problems first.
The first likely cause is a dead battery. A driver will be able to tell if this is the case by the fact that there is no sound coming from the engine and the lights on the dash do not come on. This is usually the point at drivers start to panic. The way to solve this problem is to stop and analyze the situation.
The first step is to check the posts and cables, are they correctly fastened? Are the terminals corroded? If the connections are loose, usually a good firm push with the heel of a palm can reconnect them, if not, a pair of pliers or a wrench may be used to tighten the bolts. In the case of corrosion, the battery terminals may be cleaned with a toothbrush, a little baking soda, water and a dry cloth.
In other instances, the lights on the car’s dash may come on, there may even be a clicking sound from under the hood but the engine still refuses to start. In most cases, the issue will be a discharged battery. This often happens because drivers forget to turn off their headlights and leave them on for extended periods while the car is not running, which the battery.
Drivers in this situation are often tempted twist the key and hold it in the futile hope that this will get the engine to start. Doing this for more than 10-15 seconds at a time, however, is a good way to burn up the starter. In most cases a jump start will get the car and the alternator will recharge the battery as the car is most mechanics advise against this as a regular course of
The ignition switch is a part of the electrical system and may be at fault if a car simply will not start. If there are no lights on the dashboard and battery cables are connected and their terminals clean, a faulty ignition switch could well be the culprit.
If the ignition switch in a car is bad, it will need to be replaced. Ignition switch replacement is a fairly simple procedure for people who are accustomed to working on cars. For those who are not mechanically inclined, however, a qualified auto mechanic can usually do this job fairly easily and affordably.
The engines in older cars may become flooded, creating a situation where the fuel air mixture cannot be ignited. The fix for this is to remove the spark plugs and crank the engine so that excess fuel gets sent out the exhaust.
