Fuel Pump Pressure Test

Modern electronic fuel injection systems are at once simple and at the same time a marvel of modern technology. The fuel pump draws fuel from the tank and sends it through the fuel line. Fuel works its way through a fuel rail and into the fuel injectors. The fuel pressure regulator senses engine vacuum and maintains the ideal fuel pressure. Fuel injectors spray fuel according to varying engine loads and speeds. In a perfect world fuel is perfectly metered into each cylinder through the fuel injectors at exactly the right moment to produce the best combination of power and efficiency...

Battery Terminal

You turn the key to start your car and you instead of the expected vroom you hear a slowly more sickening sound followed by the dreaded click...click...click. Even worse, you hear nothing at all. No whirr. No vroom. No action. Chances are the battery isn't getting the juice through the wires to turn the starter. And without that juice you're going nowhere. So how did your battery go dead?..

"That program is buggy" is the oft-heard phrase used to describe a computer program that isn't working right. Oddly enough, the phrase originates from the days when computers worked by way of on-and-off mechanical relays. The very first computer bug mistakenly crawled into one of those relays and met its maker when the relay slammed into the closed position. Since the relay could no longer complete a circuit, the computer malfunctioned. The hapless computer bug was discovered during troubleshooting, and the name stuck. Today, computers have come a long way from relays, and are an integral part of everything from toasters to automobiles. But wait a minute; what the heck does this have to do with fuel injection?..

High Octane Fuel

Every time gas prices creep higher, you might find yourself wondering if you really need to pay the extra change for the upgrade to premium or super duper grade gasoline. The answer to that question is no. Unless you're driving one of the very small percentages of performance vehicles with an engine designed specifically to utilize the properties of higher-octane premium gasoline, there is no performance gain in using premium. It might make you feel better, but your engine won't know the difference...
