Today, we are going to talk about installing a new fuel injector into a car. When a car starts after being put back together, it’s always a win. Recently, I had to handle a flashing check engine light issue in my wife’s Cherokee. The scan tool revealed a P206 and a P306 code, which are related to the fuel injector and misfire in the number six cylinder.
After diagnosing the issue, I decided to order the parts from O’Reilly’s, and they arrived in less than 24 hours with free shipping. I got the new injector, gasket kit, and spark plugs, as it was also time to change them. Thus, I wanted to do the job in a single go.
The process started with removing the plastic cover and intake hose to reach the fuel injector. I was careful while disconnecting electrical connectors and removing the intake to avoid any damage. As I proceeded, I changed the spark plugs, and then it was time to focus on the fuel injector of the number six cylinder.
Removing the fuel rail and the injector, I checked the resistance of the old and new injectors to ensure the faulty one was the root cause. With its high resistance, the old injector was undoubtedly the culprit. Replacing it was the only solution, and after putting everything back together with the right torque specifications, the car was up and running smoothly.
