Likely the most frustrating occurrence you can have with your vehicle...turning the ignition key over, and nothing. You're left stranded, perhaps late for a meeting. Whatever your case may be, the first thing you need to do is figure out why it will not start.

Diagnosing a no-start problem is likely the easiest one to solve. It may be a cheap or even free fix, depending on the issue. However in some cases it could lead to a costly repair bill.

This article will cover the two main scenarios of a no-start: a "dead" no-start and a "live" no-start.

A "dead" no-start is very easy to determine. Simply put, it is when you turn the key over to start the engine and nothing happens at all. This form of no-start is cause by a lack of electrical power somewhere. Here are a few tips to diagnose this problem:

1. Check your battery cables. The cables may appear to be in tact and fastened properly, but may loosen as time goes on. If by turning one or both of the cables and you notice one is loose, a small wrench or screwdriver can be the solution. Also check for corrosion on the cable ends; it will appear as an off-white substance that builds up on the battery terminal and cable end. A wire brush or small rotary tool can clean corrosion up quickly, leaving a good metal-to-metal contact.

2. Dead battery. Vehicles require a lot of amperage to turn over, thus requiring a good charge from the battery. If you turn the ignition over and nothing happens, but there are dim interior lights or headlights, chances are you need to charge your battery up.

2. Brake pedal. Many newer cars will only start if you depress the brake pedal. You may forget this safety feature if you are in a hurry. Your vehicle may be equipped with a safety button or switch located near the gearshift that will also allow it to be started once this button is pressed or switch is engaged.

3. Check the gearshift selector (automatic transmissions). A vehicle equipped with automatic transmission will not start unless it is in Park; although much older ones may start in neutral depending on the model. If your vehicle has had transmission repairs, the shift linkage may not be perfectly set up. When in Park, try pushing the shift lever a little further up and holding it while turning the key over.

4. Check your fuses. Virtually all of the electrical components on your vehicle will be protected by a fuse or relay of some sort; including the starter, fuel injection system, ignition system and fuel
