My ’86 XJS V12—running and driving as of Monday—yesterday developed the following issue:
Upon turning the key in the ignition, the engine will crank (at position 3 on the switch) but upon returning to position 2 everything will cut out very suddenly.
I also noticed that accessories that should operate in position 2, such as the power windows, are not working at all, though headlights, flashers, etc. all still operate.
Lastly, the fuel pump is not priming when the key is turned to position 2.
Does this sound like a relay issue, an ignition switch issue, or something else entirely?
Thank you to all who replied! Looks like Moss Motors carries this part; I suppose I’ll order it from them unless someone has a different recommendation (though considering the cost, attempting to disassemble and clean the original switch is tempting).
Any ideas as to how many hours an ignition switch replacement might reasonably take? Looking at my Haynes manual I see there are quite a few steps involved.
I overhauled my ign. switch several years ago, and it has given me no more trouble. It is a “fiddly” job, and I hope you are patient. A couple of hours should be enough, and repair is always better than replace, IMHO! Go for it.
