    4.0 - replaced entire cooling system, still overheating

    I know this is an old thread but I can't find anything on whether this is a straight bolt in or even anyone else that has done it (ZJ 11 blade mech fan and clutch) on this forum or others. Anyone done this?

    96 4.0 Cranks, No Start, Has Fuel At Rail

    So doing some more looking around while I'm installing these "big 7" cables, the fuse that I believe is associated with the ASD circuit is blown. I hear it's posdible that a shorted O2 sensor can blow that fuse. If the connector with exposed wires is in fact an O2 connector that would make...

    96 4.0 Cranks, No Start, Has Fuel At Rail

    This XJ is son of a gun..96 bastard year could have any combination of 91-96 (?) and 97 + parts. On top of that the engine is not original and I'm not sure what model and year it came out of. The PDC does not match the layout described in the 96 XJ owners manual; it also has two posts (battery...

    96 4.0 Cranks, No Start, Has Fuel At Rail

    Yeah looking up CPS, that definitely is not it (at least concerning the bare wires). I think they may be NSS and one of the O2 sensors (possibly downstream O2) Last time I worked on the XJ and it started everytime without issue (about a week or two ago) I had the NSS bypassed. I do think there...

    96 4.0 Cranks, No Start, Has Fuel At Rail

    I'm wondering if one of those two harness/connectors is the CPS?

    96 4.0 Cranks, No Start, Has Fuel At Rail

    At this time I don't know what the fuel pressure is. I did press the valve and fuel sprayed out. I have not checked injector signal, I'm not sure how to do that. I do have a test light and multimeter. Have not confirmed spark. Spark was what I was suspecting after seeing fuel at the rail and...

    96 4.0 Cranks, No Start, Has Fuel At Rail

    Hi, Finally got my 96 4.0 XJ cranking by bypassing the NSS, now it won't start! SMH! The last time I worked on it I was diagnosing the no crank and when I added a jumper wire from the starter relay to ground it would crank and start right up, now not having touched it in a week or two it will...

    Cooling Fan Switch And Temp Sensor Recommendations

    Thank you! Great info! There appears to be no port at the head in my XJ. I did order an additional tee to add the third unit (sender for gauge) at the thermostat housing. As of right now, I think this will be my quickest and cheapest option to get the fans running, get the PCM the data it needs...

    1996 4.0 No Crank, Starter Works When Jumped

    I wish I could post pics | : I appreciate your help brother, but neither one of those descriptions match what I'm seeing under the hood. There is an actual 6 pin (not 8 with 2 unused) and a 4 pin (internally round in shape). The XJ is the bastard 96 model and supposedly the engine has been...

    How to Confirm Suspected NSS Problem?

    I'm planning to just leave the jumper wire installed until I can repair the damaged harness wiring on my XJ. Being that it is just a supplemental ground, I can't see any downside other than being able to start in gear; but I've never, not even once attempted or accidently attempted to start the...

    How to Confirm Suspected NSS Problem?

    When it is not starting (shifter in park or nuetral) and without touching the shifter, you can test for continuity (ground) at pin 10 or you can run a jumper wire from pin 10 (strip the end of some wire, insert wire into pin 10, install starter relay) and connect the other end of the jumper wire...

    1996 4.0 No Crank, Starter Works When Jumped

    There is a 6 pin connector that should be NSS? The other connector is 4 pin and is round inside (where the pins/sockets install), any idea what this connector is? I searched AW4 connector and didn't see the same one described above. The XJ is the bastard 96 model that could be a mix of 95 (and...

    1996 4.0 No Crank, Starter Works When Jumped

    One of the connectors with missing wire insulation does in fact go to the NSS, the other goes to the drivers side (I'm guessing to control the solenoids).

    1996 4.0 No Crank, Starter Works When Jumped

    Damnit man..well, I took a closer look at the "bundle" of four connectors close to where that suspect butt crimp connection on the black with orange stripe ground wire is and man the insulation is totally gone on the wires going into two of those connectors (both appear to be heading down...

    Aftermarket gauge mounting

    I'm trying to figure this out myself but am wanting 2 or 3 gauges (oil, water temp and volts if I can fit it cleanly). I wouldn't mind pillar mount if someone made a full replacement panel, not wanting to cut or put holes in the factory piece. I have found that the XJ aftermarket is very slim...

    36 weights to balance a tire?

    Adjust tire position on wheel and retest before adding weights? Makes sense, offset imbalance in the tire and wheel themselves as much as possible before adding weights to fine tune.

    1996 4.0 No Crank, Starter Works When Jumped

    The NSS is still connected as far as I know, at least it appears so at the connector in the engine compartment (passenger side rear, near head. There are 3 or 4 connectors there in a "bundle" and all appear to be oil soaked. There is also a wire in that "bundle" that grounds to the passenger...
