have a red blinking light on gear shift . want start. when i try to lock and unlock the door all the windows go down as soon as i start to turn key. no remote.

 

What state is your battery in ?


These old Jags do some weird and wondrous things if their battery is not 100%

 

almost new 900cca

 

That's the Cold Cranking Amps, what you need to check is the Voltage.
If it is too low the control modules tend to have brain farts!

 

Did you mean to say "Won't start"? As I recall, the windows lower for a trip of the inertia switch.

 

Did not know that!


Just proves, you are never too old to learn something new.

 

Well, I am not sure my memery is correct for an X-308. What did you find?

 

okay people it's not the battery(wish someone would come up with something diff) have 5 others. 1 98,2 99's, 2 2000's. put the battery in each one for a day. no problems. changed out key/transponder from another and it turned over for a day. then found out bad fuel pumps. changed out ,now back to square one. will not turn over. now i found out the other 2000 windows come down about two inches when i unlock.not good when it's rainning

 

I found these other posts on "no crank"

"99 XJR won't start, just a "CLICK" noise" thread - Forum member Sean B comment: "The false bulkhead connector, a heavy black cable bolted to the brake pedal assembly cover and a similar cable that runs to the fuse boxes and interconnects try unbolting them and checking the connections tidy them up with sandpaper/wire wool..... A freshly charged battery too."

2nd thread - " Help! Car won't start - Hoping i didn't fry something"
Here is link to my post there --- has information about the fuses and false bulkhead connection:
