So i have an 03 jaguar s-type. About 99000 miles. I got in it this morning and put the key in and turned it over...nothing happened. They radio lights and every thing worked except the engine wouldn't star..or turn over... No clicking or nothing. No check engine light either? ?? When I take the key out I here a beeping noise? ? What's going on??

 

How old is the battery? Many, many threads pertaining to flat batteries and their symptoms.

 

+1 it's 90% likely the battery. Get a hefty one...
After that, check for what the drain is 40 mins after key out.

 

Alright thank! It was a bad battery. I replaced it, but the next morning same thing was happening. It woudnt even let me put it in neutral to start? Hmmmm? I can't get it out of park?

 

Thanks**

 

Drain is...?
