    External voltage regulator or not

    Billwill , I saw & replied to your post on the other forum . I checked battery voltage with engine off on the battery posts & got 12.76 volts . With all wires connected & the engine idling I got 14.33 volts on the battery posts . Since the engine doesn't cut out till about 2200 rpm's , perhaps...

    Ground Wire Question

    2005 Liberty 3.7 , Anyone know if there is a ground wire that comes out of the harness & has a ring terminal on it that one of the bell housing bolts goes through ? The way the harness lays across the top of the bell housing & being behind the engines heads , it's really hard to see back in there .

    Dead Jeep issue

    A bad starter wouldn't have caused it to die at the light & wouldn't have caused it to run poorly after you got it restarted .

    2005 jeep liberty # 4 injector , no fire .

    The first thing I did was swapped injectors , same problem , then I started checking wires , I verified one wire to the injector had power & then I verified continuity on the ground wire that goes from the injector to the pcm . Just to completely satisfy myself I bared a small spot in the ground...

    2005 jeep liberty # 4 injector , no fire .

    I have a 2005 3.7 Liberty & I have a code for # 4 injector . I have definitely narrowed the problem down to no ground signal from the pcm for that injector . I traced the wire from the injector to the pcm connector , bared a small spot in the wire just outside the pcm connector & there is no...

    Camshaft Position Sensor

    According to what I read the camshaft position sensor sends a signal to the PCM at the appropriate time for the PCM to send a signal to the appropriate injector & that injector fires . If that is correct , if for some reason the camshaft position sensor skips sending a signal for # 4 injector...

    Motor Mounts

    While looking for new motor mounts for my 2005 Liberty I found what appears to be the round rubber mount piece with the bolt hole in the center . It doesn't have the metal around it that bolts to the engine . Anyone ever replace the rubber part in the existing mount ?

    Need Info ASAP

    I'm pulling a 3.7 out of my liberty tomorrow if it's not raining . Will removing or loosening the one long bolt through the motor mounts allow the engine to slide forward or will the engine & transmission not raise high enough for the mount to clear the bracket the mount sits in ? 2005 Liberty ...

    Weird crank but no start (long)

    Just guessing but when you get the backfire & no start , I'd pull the plugs & see if they were all wet . Since it starts after sitting a day or two , sounds like it's flooding the plugs out .
