I'd change the plugs as per this link, and swear by an 'internal service' by chemicals as manufactureed by BG Products available on Ebay (The chemicals are for professional use so stick to the instructions). If you haven't seen this thread, take a look.

Hello Eric Lovins,

Your ignition switch goes directly to your BODY module and the engine control module... (with only a RELAY) in the mix...
for "starting purposes only"

My experience with Jaguars (magnificent vehicles) has
taught me to FIRST SUSPECT RELAYS... (easy access the switches (really hard to reach... If you plan on keeping the car
(mine being the last V12 Convertible they built)... I keep spare relays... HOWEVER...

Control of the running (or not running) seems to be the
Ignition control directly from the steering column to the BCM.

Logically your Ignition switch (highly used & difficult to get to) should be most suspect... (there are also high risk of triggering logic circuits with RESULTING AIR BAG DEPLOYMENT (EXPLOSIVE FORCE))... Use of care and full knowledge
is advised here...!!

I have the Factory Service Manuals for MY '95 XJS...
They are impressively expensive... but WERE cheaper
(NEW, PAPER) than a single "visit" to one of my
neighborhood JAGUAR DEALERS...
(assuming all thing go well... they usually don't).

While the Factory Service Manuals are collectors items themselves you might remain in convinced of their inherent value... you can use the FREE data base at BBB Industries
website... (registration required)

(also see Jag Lovers site below (very bottom)).

I found no Technical Service Bulletins on your ignition lock
(a good thing)...
but in my car it would be very simple to eliminate DOWNSTREAM electronics... simply by removing the wire from the ignition (the engine should stop)

You can then confidently pursue that wire into your ignition lock...

My vintage vehicle has no PATS (passive anti-theft system) keys... but I will assure your life will be happier if you make SURE you have all the required keys & fobs BEFORE you get into the lock.

i dont think there is a seperate fuse for the fuel gauge the only fuses are for the instrument pack if one of these fails other instrument pack functions would be affected also, the usual cause of fuel gauge problems is the sender unit in the fuel tank it is located behind the trim panel forward edge of boot, or a wiring fault,

If the key won;'t work, your only other solution is to remove the rear seats. You may be able to reach through the rear seat bulkhead and pull the release catch.

if the wires are on the right plug then you could have injector problems. when you changed the plugs did you gap the plugs to specs as if they aren`t then it can cause this problem. you could also have one or more bad ignition wires.

Happens a lot. Always use the best high octane you can find. Check wire connections to knock sensor (most common cause for 'restricted performance light, sometimes outside temperature plays a part). Then disconnect negative terminal from battery, wait 2 minutes, reconnect. Then take car for a drive in various conditions, like city traffic, highway driving, and more. After several restarts, mine went away. Occasionally comes back, then disapiars. Ignore orange engine light.
