    Agree with above post . The 2.5 liter or the 4.0 ? Also , the second post shows a CJ7 trailered . You mentioned a trade , was it the CJ for the YJ ?

    Switches

    Pardon me for saying , but the jumpers on the fog light switch are crossing each other which most definitely will cause an arc. Sorry about that �� .

    I cannot identify that " module " , I'll call it , or its purpose. I'll have to say it's an add - on since its zip tied and fastened with sheet metal screws . Can't find it on a FSM ( factory service manual ) . Curiously , we would be interested where it's wiring goes and connects . Ok , a oil...

    If the cylinders have been soaking a reasonable amount of time , you can try to bar it over but if the engine didn't break loose with a few tugs , I think the breaker bar wouldn't yield much results . You can pull the cylinder head to get a look at the condition of the cylinders if you've got a...

    On the first picture post , the casing is clearly split and at the minimum , must have been arcing but what oil,is packed from the factory is long gone . Give it last rites and pitch it . On the second picture post , that's the front axle shift motor . Won't have any bearing on the no start ...

    I don't know if that trans has a vacuum operated shift modulater , which are normally fitted into the body of the trans , above the pan . They work with the valve body to control shifting . But the problem of down shifting is still the kick down / throttle valve , which I believe is a...

    Jeep Liberty Sport 4x4 Heater Problem.

    Is the issue that if losing air flow as previously suggested or is it that the temperature drops from warm to cold ? In later model jeeps there are issues of blend doors in the duct work that cause such problems as your experiencing but I'm also reminded of a friends wife's ford van which had a...

    It's good to hear that you've made progress with repairs that have made such a difference toward improving the jeeps comdition. It was very wise to remove the clip you found in the throat of the carburetor . That wasn't a wise thing for the previous owner to do since there was a major risk of...

    Thank you for your reply . the reason I stress " COMPUTER SAFE " is because I learned the hard way years ago why. We must test computer circuits with computer safe equipment . A NOID light just makes it easier in addition to being computer safe . The power for the injector circuit isn't a...

    In addition to engine compression , intake and vacuum , valve timing ( timing chain ) and fuel delivery ( fuel pump ) and ignition timing and carburetor adjustment as well as state of tune , carburetor condition may have to be considered . not just base plate gasket seal is to be checked ...

    Agree that a compression test should performed to determine the engines health . Also , test the intake manifold for intake leaks at the base gasket where the carb bolts up but more in particular where the intake bolts up to the cylinder head . In - line engines are known for intake leaks there...

    You may If you want to check the auto shutdown relay , just swap a known good relay in its place . The a/c relay will do . If you wanted to bypass , jump terminal 30 to terminal 87. But use a good relay to maintain connectivity. Although the last check of the crank sensor revealed good , keep an...

    Engine Temp

    It is possible the thermostat could be stuck open . That could mean the thermostat is faulty . Hasn't happened to me in a while but it has so I still keep that in mind if this should happen . eventually , after a long drive , the engine coolant gradually gets hotter and doesn't cool efficiently...
