Jeep Information


Engine:3.8l V6

I dad a code for a bad O2 sensor. I replaced the sensor and now the engine won't start. It cranks but no ignition. I checked every fuse with a meter and they are all good. Even replaced the computer but still wont start. Also tried putting the old O2 sensor back in, no luck. Help!
