I am currently trying to sort out the Starting/Ignition system on a 1988 XJS V12. It turns over freely but it seems like it isn't going fast enough for it to actually fire up. I am starting to think that there must be a boost coil for the starter to fire up the 12 cylinder beast! Is there anything I am missing or should know ?

 

The correct forum for your car is just below this one in the forum list. You'll get better answers there, I reckon.

 

Thank you sir! I will post my question there!
