ok i got a 1996 xj6.. the car was running fine on saturday, then on sunday morning, leaving for work the doors wouldnt unlock, when i used the key to unlock it it just unlocked the driver door and the interior lights didnt come on. i turned the key and the gauge cluster lit up and everything appeared fine until i turned the key all the way and i got no noise. it didnt even try to start. tried jumping it just to make sure it wasnt the battery and still nothing. anyone have any ideas???

 

also, i cannot access the gas tank since everything is locked.... need replies!!! please...

 

abut the gas tank, you can access it from the boot. just take off the liner and you can unlock it manually.

 

An easy place to begn is carefully checking the battery cables at the battery. Are they clean and tight? Really tight?

These cars are very sensitive to battery condition and such.

Also, there are "+" voltage junction/distribution posts at the firewall and at the fuse boxes at the right left fenderwells.

There ae many other possibilities (including many other places where a poor connection can occur) but you got begin somewhere.....

thanks for the advice. i tried everything, and still cant get it started. i just put the car up for sale this morning...

 

Did you find the inertia switch ?.....Roger.

 

key only unlocking the driver's door is normal, but I think you should've gotten interiour illumination. Takes a double-twist to unlock the rest of the doors. Sounds like inertia switch or something afoul of the security system...somehow it isn't satisfied it should restore the starter-interlock.

Nahh..wait...am I mixed up? I think inertia switch would let you crank, just never start...it secures pwr to the fuel pump, no?

 

Bought the car around June 28th. No start problem, so selling it on the 30th ! Do I believe this ?.......Roger.

 

On mine if you lock it with the remote and then for some silly reason unlock it with the key ALL the doors etc unlock, BUT, if, when locking with the remote it has activated the security system (single chirp as you lock it), the key will unlock the drivers door only, and the car is still in "dead mode".

If you locked the car with the key (not using the remote) and activated that chirp, it SHOULD unlock everything with the key again, and then you turn the ignition to position 2 to de-activate the security within 30 seconds??.

The enertia does only kill engine start as you thought, it will crank all day, but no fire.

I reckon you have a battery issue, or voltage out of battery issue, OR the syecurity system is just having a Jaguar moment, and that can be anything I suppose, and having never experienced one of those moments I am not much help.

A common suggestion, and Doug has mentioned it, is to remove the battery cables, clean them as mentioned, and resecure them. The removal will/can "clear" any issues, and the cleaning will do no harm.

You may be lucky.

 

Apart what I said just a minute ago, try relocking the car, then unlock it again, maybe it will clear whatever is wrong.
