    O2 Sensor issue

    Agree with the o2 foolers. I had the same issues with my aftermarket catalytic converters. Added one on each down stream cat. No cel. Be advised, only ngk o2 sensors work properly. The voltage high indicator implies a non ngk sensor. Mechanics can be wrong! The sensors are relatively easy to...

    2012 Jeep Wrangler Unlimited Sport Heater Not Working

    Two things I experienced when I did the heater core flush and had to replace the blender door actuator. I also had no heat. First I burped the coolant to remove the air bubbles. Parked Jeep on an angle with the front end up. Opened radiator cap (when cold). Using funnel added coolant until no...

    No start, no crank (still) 2007 JK

    I had the same issue. You can view my previous posts as to what I have done to my 12 jku. After much frustration and more frustration. For me it turned out to be the security fuse/breaker. I pulled it out. Cleaned contacts. Moved several breakers/fuses around. Now, no more starting issues. Knock...

    2012 Wrangler JKU, no start, no crank issue continues

    That’s probably what I’ll do for now. At least until I research the dreaded anti theft system more. Just happy it’s not the transmission neutral switch. One thing I find most interesting. On my 69 mg midget, repairing and maintenance is so much easier without all the systems car...

    2012 Wrangler JKU, no start, no crank issue continues

    Update, after several days of driving the no crank no start came back. I pulled the m13 fuse. And it started right up. So my issue seems to be with the anti theft system. Again, when this happens the anti theft light does not stay on. I’ll be investigating the skim unit next. The dealer wants...

    2011 Jeep Wrangler no crank, no start

    Following, have the same issues with my 12 jku. My jeep specialist said it is the skim module ( anti theft) . I’m starting to think it’s the automatic transmission neutral switch. (Inside the transmission) .

    2012 Wrangler JKU, no start, no crank issue continues

    Possible, but unlikely. Brand new mopar factory wire harness. New factory fuel injector harness. I’ll be looking at that next. It’s got to be a bad ground somewhere. Thanks.

    2012 Wrangler JKU, no start, no crank issue continues

    Auto trans. Jeep specialist tested starter current and connections. All good. He also tested when the malfunctioning was taking place. With direct connection to battery, starter worked. Also, while non starting, checked fuel injectors for fuel flow. They worked for a nano second, then shut off...

    2012 Wrangler JKU, no start, no crank issue continues

    Yes starter does nothing, no click, nothing. As my previous posts have noted. Everything electrical works. The only warning light is the lightning bolt, and cel, both go out after a short time. No anti theft light other than the initial come on. What I have done recently, other than...

    2012 Wrangler JKU, no start, no crank issue continues

    Ok my issues are still ongoing. To recap, random no start no drank after driving about 30 minutes. I can get it to start by using the battery cable remove, touch, reconnect . All power is on and works when this happens. Jeep specialist had it for a month, replaced the ignition. Threw codes...

    Bad blend door actuator? No heat, lots of cold

    I have the same blinking light. My understanding is that the hvac system is resetting itself. Mine appeared after I replaced the center blend door. Got the dreaded clicking and was driving the wife crazy!!! It’s a real pain to get to. Now I have a code that says blend door restrictions. No air...
