When a driver turns the key ignition to the start position and the engine does not turn over or “crank,” the possible problem could be as simple as a loose battery cable, or on the other hand, something more mechanically catastrophic. Let’s start at the simple end of that spectrum. First of all, we are forced to ask the most embarrassing question; If the automobile has an automatic transmission, did the driver/operator check to verify the transmission is in the PARK position? Most late model American cars will not start otherwise. Likewise, if the vehicle has a standard transmission, the clutch must be depressed on most newer models before the starter will engage. Assuming these preliminaries have been properly handled, next consider another simpler scenario. A substantial change in climatic conditions, temperature, humidity and such, can foster corrosion and subsequent bad connections between the cables that provide current from the battery to the starter motor. Since the starter requires significant current, even a small amount of resistance can prevent proper operation. The starter solenoid makes a clicking sound when it engages, but even if this sound is heard, the battery still may not be providing enough current for the starter to turn the engine over. First check the battery cable connections by giving then a slight twist or turn. If the problem persists, perhaps the battery it self is dead and needs be replaced. Most batteries have a life of 3,5 or 7 years and the batteries life is usually advertised on the battery itself. In addition, there is usually a little sticker on the battery with punch-outs for the month and year the battery was installed in the vehicle. A check to be sure the battery has not reached its end of life would be prudent. If it has, the battery should be replaced. As a temporary solution, a jumper battery or jumper cables to another vehicle can be used to start the engine. Once it is running, it will continue to run off the voltage produced by the alternator. But, if the engine will not crank using a jumper battery or cables connected to another vehicle, a more catastrophic problem may be indicated. Generally, the fuel and spark ignition systems can and should be disregarded at this point. In most newer fuel injector type engines, the fuel pump, injector system and ignition systems will not be activated until the engine develops oil pressure, which occurs only Category:Home › Autos • Will the trend toward economy-size car models lead Americans back to buying smaller-sized cars? — part 2 • You should never use after-market auto parts when maintaining or fixing your car • Should a new car be rust-proofed? • Will the trend toward economy-size car models lead Americans back to buying smaller-sized cars? — part 1 • Five safest cars in North America • How to ensure your teen drives safely after getting a license • Pros and cons of using an hydrogen generator for your car • DIY automotive maintenance: How to change the oil
