Hi,
Suddenly my 96 4.0 automatic would not crank after the last drive (maybe 2-3 weeks after parking it). When I hit the key, I get power at the dash and keyed power accessories work but when I turn the key fully to the start position, I get a single clunk/click and the brake idiot light lights up. I did all the easy stuff like cleaning grounds, battery terminals etc. Doing some searching, I thought maybe it was an NSS issue and tried moving the shifter through many cycles and then starting in both park and nuetral..no go | :
So here is where I am at now..I can start the XJ with it in park and key on by jumping the starter with a screw driver and by removing starter relay and jumping terminals inside the pdc. I'm guessing this eliminates everything else in the system including the starter, power/ground wiring, ignition switch and NSS? I tried swapping a different relay (I believe it was the electric fan relay) and that did not solve the problem, but I'm not sure if that relay is good (the XJ has an aftermarket triple electric fan setup with standalone relay not triggered by the PCM). Is it likely the starter relay that is causing the no crank?
Thank you!
