have an injector misfire, or low fuel level. Could be a short . I would check your wiring connection.

If you've replaced the fuel injector, spark plugs, and fuel rail, but the P0202 code (cylinder 2 injector circuit malfunction) persists and your Jeep Liberty is misfiring with a strong gas smell, try these steps to find the issue.
Check the wiring and connector for damage, use a light to see if the injector on cylinder 2 is getting the right signals, check compression in all cylinders, verify fuel pressure meets specifications, look for vacuum leaks in the intake system, inspect the wiring harness for the fuel injector, and ensure proper wiring continuity between the ECM and injector. If issues persist, consider professional help, as it might involve the ECM.

Whoa there, Jeep Wrangler warrior!
Hold your horses before you declare your Liberty kaput. Getting that P0202 code stuck on repeat for cylinder 2, even after replacing the injector, rail, and plugs, can definitely be enough to fry anyone's circuits. But fear not, fellow gearhead, let's troubleshoot this bad boy together and get your trusty steed back on the road.
First off, replacing those key components was a solid first step. It eliminates some common culprits. Now, let's dig a little deeper:
- Wiring woes: Double-check the wiring harness for cylinder 2. Look for any loose connections, chafing, or damage. A bad wire can disrupt the injector's communication with the engine computer.
- Hidden gremlins: Did you clean the injector connector when you replaced it? Dirt or corrosion can create resistance and mess with the signal.
- Vacuum leak: An air leak near cylinder 2 can mess with the air/fuel mixture and cause misfires. Check for any loose hoses or cracks in the intake manifold.
- Compression blues: Did you measure the compression in cylinder 2? Low compression can also lead to misfires. If it's significantly lower than the other cylinders, that could be a sign of deeper engine trouble.
Remember, with troubleshooting, patience is key. Take it step by step, and don't hesitate to consult a trusted mechanic if you get stuck. And hey, if it does turn out to be a more serious issue, chin up! At least you know you gave your Liberty a fighting chance, and that's more than most rides can say.
