P lease help! I'm a new owner to a 2010 xkr that I recently purchased with 47K Miles. I let the car sit for 3 weeks and the battery was dead. I read a lot of posts on this forum and attempted to "jump start" the battery with a donor battery and had no luck. The electronics came on progressively but there was never enough juice to start the car. I got a brand new AGM battery and installed it yesterday. When I went to start it, it STILL won't start. Not even a crank or click of any sort. I do have full electronics now but, I don't understand why it won't start. There aren't any warning lights on and nothing is different other than the car doesn't start. I know this car is chuck full of electronics. Am I missing something that I have to do or reset after a new battery install??? Please help me. I don't have a very local Jaguar dealership to take the car to and am hoping that this is a "simple" fix. Anyone else have this issue with their 2010 XKR?

 

<p>Dagny - most folks on here use some type of&nbsp;battery tender to keep the battery charged when not in daily or frequent use. &nbsp;As for why you can't get her started, I will defer to those more knowledgeable.</p><p>As this is your first post, please stop by the New Member area and post an intro - in return, you will receive a warm welcome and useful tips for forum navigation.</p><p>New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum</p><p>&nbsp;</p>

 

The first (actually, second - see the next paragraph) thing I would do is take that new AGM battery back to where you bought it and have that retailer test it to make sure that it is fully charged and fully functional and that it is a proper replacement for the OEM battery. If everything checks out OK and after you correcly reinstall it your car's dashboard and touchscreen power up but your car still doesn't turn the starter motor over, I would suspect a bad starter or something fried in the starter circuit. I haven't checked, but I'd see if there's a fuse for the starter and if there is and it's still good then I'd suspect the starter or the solenoid. Hopefully, other Forum members can give you better advice.

Another thing is that the XK/XKRs won't start unless the brake pedal is depressed. Try pressing the starter button BEFORE you step on the brake pedal. Inadvertently pressing the brake pedal multiple times causes a high pedal, which can make it much harder to close that starter interlock switch and it gives the impression that the car won't start. I'd try this first, before my above suggestion.

Good luck and keep us posted.

check the fuse panel in the engine compartment make sure all the fuses are good I had a problem where one fuse was out and when I replaced it car started dont remember which one so check all of them

 

This may or may not have any bearing on your particular situation, but when you are attempting to start the car is your driver's side door open? My 2010 XKR will not start if the door is open more than half way. Close the door all the way and try it again.

 

I am new here so please have patience! I need to find out the exact type of battery to purchase for my XJR 1996 Jag....has been sitting too long and battery is done.
Autozone "chose" a battery after looking at my specs but it will turn on lights only but will not crank. What are the cold and other cranking amps required.

Maybe the key fob is the problem. Do you have another one to try?

 

A 12V battery is a 12v battery no such thing as wrong one!
Have you tried bypassing the key FOB using your emergency key? see your owners manual if you don't know how!
are headlights bright? new batteries often need charging before use.............

Cheers, Adrian

 

Just an FYI https://www.batteriesplus.com/batter...l6-4.0l-590cca
Let the internet be your friend

 

using actual key since nothing "electric" including remote fob is working...put new battery in, all dash lights lit, steering column started adjusting, but no "click" , as in no attempt to start ...car has been sitting a long time so someone suggested the started had "seized", suggested tapping on it from underneath engine to slightly dislodge it from possible rusted position while starting to crank...?????

 

Nothing wrong with giving the starter a few love taps with a hammer, old school trick right there. I would suggest insuring the battery is fully charged as stated above, and trying all the other advice in this thread.

 

Not always so. Depending on the chemistry they have different charging needs. Some are wrong for an S-Type, for example, and will never be properly charged (it has a smart charger tuned for lead acid and nothing else).

Newer cars are getting more "awkward" due to all the electrical items...

 

Gosh, this makes for annoying, frustrating reading . . .

. . . until I realized that once more, a 5-6 month old thread (presumably the OP [Dagny] resolved, sold, or blew up his 2010 XKR) was then hijacked (I guess unwittingly) by a noob.

Best and kindest advice would have been . . . please, start a NEW thread!
(I'll lie down now)

 

Better yet, this is the wrong Forum!
Marybeth please start a new thread under XJ's. This Forum is for Al. bodied XK's..................And I didn't notice the dates, silly me!
Of course, you should get similar advice! same engine etc............
Do you have a code reader? mandatory for modern cars!!!
I have two; carry them in both Jaguars including a spare computer module for my wife's XK8....
A while back I fixed a XKE with stuck starter by rocking it in gear; sorry, no help to you...........
Good Luck, Adrian

 

After a whole day of trying everything else, pressing down really hard on the brake pedal did the trick.

Thanks Stuart!

 

David,
You're welcome, and I'm glad I could help. I'd appreciate a in my post #3, above.

Try pressing the START button before stepping on the brake pedal. If you still have trouble pressing the brake to start, the repair described in the above link may be necessary.

try jiggling the shifter as you crank it over when in park

 

Holy revived threads Batman!!

Keith, you do realise that you've replied to a thread where the previous post was from 2016!?

I'd think if they couldn't start it by now it'll no longer be in their possession
