How long do GM fuel injectors last?
between 50,000 and 100,000 milesThe fuel injectors on your car will typically last between 50,000 and 100,000 miles. The length of time that the injector lasts has a lot to do with the type of gas that is used in the car and how often the various fuel filters are changed.
Does upgrading fuel injectors increase power?
The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.
Are all fuel injectors the same?
There are two distinct types of fuel injectors: high impedance units, and low impedance units. A high-impedance injector (aka saturated) uses a high resistance value of around 12 ohms across its coil, but runs at low current levels to keep the circuitry cool.

Is it worth changing fuel injectors?
Some fuel injectors are rated to last one billion cycles or approximately the lifetime of the vehicle. But when you factor in the adverse conditions experienced in real-world driving coupled with a lack of proper maintenance, most fuel injectors might need to be replaced every 50,000 to 100,000 miles.
Do bigger injectors need a tune?
In general, injectors need a tune. Otherwise, your ECU is trying to drive the new, bigger injectors using the duty cycle and dead times for the old, smaller injectors, which means too much gas potentially at the wrong time (i.e. - running rich and potentially missing).

What happens when a fuel injector leaks?
Thin Oil – When a fuel injector leaks, all of that fuel is not getting burned in the combustion chamber. Any gas that is not fired and sent out as exhaust ends up in the oil pan. When this happens it can decrease your Yukon’s engine lubrication to the point that it’ll lock up. You will smell fuel on the dipstick.
What happens if fuel injectors aren't working?

What is the name of the Bosch fuel injection system?
The earliest reference is the Jetronic –the Bosch name for its early fuel injection system. This connector evolved into the Minitimer that now morphed to EV1. Right away, this becomes mystifying with three different ways to describe this electrical connector.
What injectors are used in 2005 LS3?
Perhaps a bit earlier, around 2005, GM switched the passenger car injector style to the Gen IV, short LS3 style that uses the EV6 or USCAR connector. This is the shortest injector of all the factory squirters, but its size should not be confused with a lack of flow potential as these injectors can crank out the fuel.
Why don't fuel rails work on different engines?
It should also be noted that Aeromotive warned us that they don’t recommend adapting fuel rails to different engines because of the potential for a high pressure fuel leak between the fuel injector and the rail. This warning would likely also extend to use of adapters.
Why are Bosch injectors less popular?
These units are becoming less popular now mainly because they don’t deliver the high flow rates now demanded by today’s more powerful engines. These Bosch injectors used a connector that is referred to by no less than three different aliases.
Does GM carry injectors on trucks?
Unfortunately, GM didn’t carry this injector over to the trucks, choosing instead to go with an entirely different injector.
Do truck injectors need an adapter?
Since most aftermarket EFI systems target the more modern EV6 injectors, using the early truck injectors will often require an electrical adapter. (Left) This is the original Bosch Jetronic injector with its EV1 connector that is also called the Minitimer.
