I need help.

My jaguar S-type 2000 won't start.
After having difficulties turning it off, now it won't start, and now it has the driver airbag light always on and it won't start.

Any advice on fixing this problem?

Thanks in advance.

Engine? Gearbox?

 

It's the engine.
The dashboard lights light up, but it won't start.

 

Check your battery, sounds as if it's gone or very weak. Go to an auto parts store and get a hygrometer and check each cell, bet one or more is weak. If so, replace battery.
Good luck

 

Thanks a lot.
The battery was ok but the relays located beside the battery was sulfated.
I used the contact cleaner and the situation was fixed.
Thanks again,
jllantin
