HI! May be it was already here, Jaguar XJ 6 1997, 3.2, not starting, turning key, lights on the dash coming on, but nothing happened after, engine not starting, even not trying to start, what can it be?

 

Wrong car forum, you have either an X300 or X308.
Anyway, a trick which AA uses, is to hit the starter motor with a stick.
It's not Voodoo, The theory is that the starter brushes might be worn, and a bit of vibration might cause them to make contact.
If it was a low battery, I guess you'd see some dimming. You do have a charged battery, right?

 

Thanks for the answer, yes, its x300,x330. Its new battery on it, will check starter and wires first
