Fuel injectors tend to fail after 80,000 miles
To prolong the life of fuel injectors, it is recommended to follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors. If fuel delivery system symptoms are present, a technician will first conduct a visual inspection. If the issue isn't clear, they will connect a computerized scanner to the vehicle to read its sensors. If there is a fuel injector problem, the technician would likely find that misfires are happening frequently on one cylinder. The fuel injector or injectors in question must then be tested and may require removal for bench testing.
There have been reports of issues with the GM fuel injectors, with some owners reporting that GM has moved the injectors from the power train warranty to the Bumper-to-Bumper 36,000-mile warranty. This has caused frustration among some owners, who feel that GM is not adequately addressing the problem.

Fuel injectors require little maintenance
Fuel injectors tend to fail after 80,000 miles, but they require little maintenance. To prolong the life of the fuel injectors, follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors. If your truck has 145,000 miles on it, you may need to replace the fuel injectors.
Fuel injectors take the gasoline pumped from the intake and spray it into the engine using a fixed or electrical aperture. The gas is turned into a fine mist that the fuel injectors conveniently shape into a cone.
Fuel injectors can become clogged, but there is a general disagreement between vehicle manufacturers, automotive maintenance professionals and even DIYers on this issue. While vehicle manufacturers have logged thousands of hours of tests without encountering a single clogged injector, the test vehicles were run under “laboratory” conditions rather than “real life” driving conditions. The engines were never shut down, but instead were allowed to run continuously to rack up as many test miles as possible. The fact is that fuel injectors, particularly port type injectors, do become fouled. The speed and frequency at which fuel flow restrictions develop depend on your driving habits, ambient environmental conditions, vehicle design, and fuel-related factors.
Fuel-injector cleaning is often recommended by shops and dealer service centres, but it probably isn’t necessary unless it’s correcting a running problem. If the injector is going to be in use for an extended period, it should only require periodic chemical cleaning. The fuel injection pump does not need to be replaced right away unless it has become contaminated with fuel. All filters should be changed as a precaution. Certain fuel injectors have been seen to run for over 100 million cycles, suggesting that they will last for many years to come.

To prolong the life of the fuel injectors, follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors
Fuel injectors in a 2006 Silverado will typically last around 50,000-100,000 miles, but this can vary depending on driving style, road conditions, weather, fuel quality, and maintenance cycle. To prolong the life of the fuel injectors, follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors. Regularly inspect and clean the fuel injectors to prevent deposits from building up, which can reduce efficiency and shorten their lifespan. It is also important to change the engine oil and filter regularly and replace fuel filters regularly. Using high-quality fuel and integrating fuel injector cleaner into your maintenance routine can also help extend the life of your fuel injectors.

If there's a fuel injector problem, the technician would most likely find that misfires are happening frequently on one cylinder
Fuel injectors tend to fail after 80,000 miles, but some sources suggest that they can last up to 145,000 miles. To prolong the life of the fuel injectors, it is recommended to follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors.
If there is a fuel injector problem, a technician will likely find that misfires are happening frequently on one cylinder. This can be caused by a dirty fuel injector, an open or shorted fuel injector, or a problem in the fuel injector driver circuit (wiring or PCM). To diagnose this issue, a technician will first conduct a visual inspection. If the issue isn't clear, they will connect a computerized scanner to the vehicle to read some of its sensors. The fuel injector or injectors in question must then be tested and may require removal for bench testing.
One way to test for a faulty fuel injector is to swap it with the one beside it and see if the faulty cylinder moves. If the problem stays in the same cylinder, it is likely not the injector itself but could be the wiring. Another method is to use an old long car antenna to listen for a "tick" when the engine is running.
It is important to note that ignition problems, such as worn or fouled spark plugs, bad plug wires, moisture on the plugs or plug wires, or a weak or dead ignition coil, can also cause misfires. Therefore, a comprehensive diagnosis is necessary to identify the root cause of the issue.
