What could be causing problems with starting a car?

Answer by  viridis (59)

An engine requires three things to start: air, fuel, and spark. Spark is provided by the spark plugs, which get fouled and must be replaced regularly. In modern cars, air and fuel are typically regulated by electronic fuel injectors. Owners can typically check the air filter, and replace if necessary; fuel filters can also clog but are harder to replace.

First have your battery tested, if ok check your starter make sure your its ingaging with when switched on. Also check your fuses for the starter. If you have an non-factory alarm check your conections for the starter wire.

When you turn the key if it makes rapid clicks then its most likely the battery, terminals or cables. A single click could be the starter.
