Replacing a Fuel Injector

This little engineering marvel is what is known as a fuel injector. It's purpose when working is to spray fuel into the engine at just the right time to be ignited and produce power to wheels of the car and cause movement. At a cost of $180 it's an expense that has to be reckoned with when trouble comes from this part. I can tell you that when it sticks open a profuse amount of smoke is generated from the tail pipe and no more than 100 miles can be squeezed out of a tank of gas. After searching out other ways to replace the little jewel which included junk yards and internet sources, a new injector arrived via UPS for a cost of only $85 and installation plans began.

The internet is a wonderful thing. Research can be accomplished on just about anything possible. That goes for mechanical proceedures as well. After much time spent on how to replace the tiny little part, I was armed and ready to attack the job with confidence and vigor. As you can see this part is not exactly right on top fo the engine ready to be plucked out and replaced. After much contemplation, deviation from the recommended proceedure was decided and a saving of time perhaps as much as 4 hours was accomplished. Oh, yeah.

When working on car things, invaribly things will be dropped in the process. This project was no different. Even though care was taken twice a socket was dropped. Now when this happens one can only hope that what's been dropped doesn't come to rest on a part of the engine that is inaccessable to human hand. So as the socket bounces it's way downward my breath was held and a celebration dance in the middle of street overcame me when I heard the socket hit the ground under the car.

It was a very good day and in the span of maybe 2 hours wrench bending time the little fuel injector that couldn't was replaced by one that could. The moment of truth is always a nerve racking moment. As the key turns and the starter spins the engine the second it catches and sputters to life chugging and shaking as the gas lines pump there liquid up to the injectors, a feeling of accomplishment spreads over me as the engine smooths out and runs just like it should. Yea, another mechanical accomplishment done. Thanks Dad for all those times we worked on stuff together. I really was watching and learning even though it didn't look like it.
