Yes tbird6 they all are the bosch type relay, I did that couple of times and nothing... So it has to be an "Electric interruption" on the 30 terminal of the Fuse Board, not the Relay itself. Thus I will Hotwire it (30term) today and the engine should crank but then the true question, why is there an interruption???
I checked the fuse F27 for the starter and is fine. So are all the other ones that deal with ECU, ignition, Starter etc...

Sounds like the PCM is refusing to provide the power. Which would most likely be because it's chosen to (anti-theft etc) but could possibly be a PCM fault. The former is the one to chase first. Check online etc sources for all the reasons the PCM would refuse to crank. Or a competent jag tech 
I would NOT bypass any relay without knowing I'd done all the checks first, plus checked the circuit diagrams very carefully, and even then on such a hi-tech car.... maybe not.
If the PCM is disabling crank it'll disable the injectors, too.

mystype4, please take jagv8's advice. By-passing a circuit by providing power via a jumper may short circuit expensive modules. I wouldn't do it. Even if your brought the car to a certified Jag tech and he found a simple solution out of this, your saving tons of money compared to if she becomes more screwed up. Just think of it...she started before you simply re-set some A/C relays...it can't be too complicated to get her going again? There are way too many sensitive electronics to gamble with. Get her to a Jag tech, please.

★★★★ relay wiring diagram bosch
Uncategorized
♔♔♔
The following Relay Wiring Diagram is produced by Bosch. These wiring diagram and electrical circuit work with most American, Japanese and Korean cars. Herein you will find detail illustration and description of Bosch relay wiring diagram including Alarm Trigger Inverter, Engine Disable System, Ignition Kill Circuit (to prevent car from starting after the alarm has been triggered and until alarm is reset), parking light flasher circuit, two-way flasher, flasher circuit for European cars (this circuit using two relays, and will work with BMW, Audi, Saab, Mercedes Benz, Jaguar and Roll Royce), positive-switching door locks, car alarm, fake alarm flashing LED, Active Antenna Driver, ignition bypass to eliminate noise, AMP system remote power switch, basic fog light switch systems, horn alert with buzzer.

★★★★ jaguar xj6 charging system circuit diagram
Uncategorized
♔♔♔
The 1993 – 1994 Jaguar XJ6 charging system includes the alternator, an internal voltage regulator, a charge indicator light, load dump module, the battery, an ignition ON relay, an in-line fuse and the wiring between all the components. The charging system supplies electrical power for the ignition system, the lights, the radio, etc. The alternator is driven by a drivebelt at the front of the engine. Below schematic shows the Jaguar XJ6 typical Charging System Circuit. The volt regulator limit the alternator’s voltage to a preset value. This prevents power surges, circuit overloads during peak voltage output.
---------------------------------------------------------------------
I don’t know if this diagram applies to our S cars, but the 30 terminal wire comes straight from the Battery and it is shared with the starter Solenoid too, so, should I check and see if the solenoid gets any electricity?

Great tutorial here: how to test a "Starter Slenoid"?

The car is FIXED!!! Apparently the way the Fuse cover and the car's Manual Fuse drawings showed the F27 fuse spot directly line up with the rows above of fuses, so I constantly assume it was on the right spot. Well I took the fuse box apart and found out I was using the wrong fuse spot the whole time.
Well thanks again,
JG

Totally awesome! See what the fruits of our suggestion bore? i.e. going over your work, especially if the car started before yanking fuses, relays, etc. Now I'd love to hear that your'e planning to uncork the STR's intake and exhaust with: K&N flat panel air filter, hi-flo cats, x-pipe, 2 1/2" pipe, delete stock resonator, flow through mufflers, 1.5 pulley, low temp. thermostat, ECU tune = "BPG" (big power gain). Now you must wait for Riski's reminder post that I'm "nut swinging" on the full exhaust mod, LOL!

Glad it worked finally
Now I have similar problem,
Jag/XJ8/2000 with 90K
The car was running just fine until yesterday, as of a sudden the car went into immobilizing mode, not a single electronic work anymore, only the driver side door can be unlocked manually by the key and the only blinking light is the red led next to the J Shifter.
There was nothing I can think of done to trigger this, no work, no fuse swap, nothing. Just as of a sudden
I tried lock/unlock the door technique, on/off ignition, open/close all doors, etc. nothing worked really. The trunk can not be opened (keys or otherwise) so I can not disconnect the battery at the moment.
Any good suggestion?
Thanks in advance!
