Probably a sticking piston. You do not grease brakes!!!

The error codes P0251, P025B, and P025C indicate an issue with the fuel system. The P0251 code suggests that there is a problem with the fuel injection pump, while the P025B and P025C codes indicate issues with the fuel pump module. Given that the car is not firing up consistently, it's likely that the fuel system is not delivering enough fuel to the engine. This can cause the car to go into limp mode and eventually cut off. The P2463 and P246B codes are related to the diesel particulate filter (DPF) system, and the B1412 and B100D codes indicate issues with the climate control system and passenger airbag. Based on the symptoms you described, it's possible that the fuel system issue is causing the other error codes to appear as well. It's recommended to take the car to a qualified mechanic or a Jaguar dealer to have it diagnosed properly. They will be able to use a diagnostic scanner to read the error codes and perform further tests to determine the root cause of the issue.

There is a small bulb or an LED under the cover. Some are replaceable, some are soldered.

The car is showing a hard code which I would need to tell what is the problem when the computer locks it out it mean a danger problem is set good luck Mike L.

bad damper motors, defrost mod. you mean wind shield defrost vents I am sure,.

On most glove boxes there is a tooth moulded into the actual hinge on the lid panel. This tooth rests against a spring loaded switch behind the glovebox. When you open the lid it opens the switch and turns on the light. You usually have remove the whole glovebox to access the switch.

PO251 is Injection pump metering control problem according to my list of codes Get a leak down test done on the injectors to see if they are ok as generally they are the reason . Also pull the fuel filter and drain it into a clean container and check for swarf in the fuel. The replacement parts. The glow plug light coming on is a related issue.

no sequence, just stage thema all down in 3 strags hand tight first. then stug, make sure it is all fitted up snug. and add torque wrench. say 5 ft/lbs. then 1/2 max then full max. just like all things like this. (head bolts a whole other matter) basic mech, engine 101 facts.

we can't tell you what you can do, lacking skills and tools and spares. I can tell you what a shop does. sure. P0300 means all cylinders of the engine are missing, means (physics) weak combusting on all cycl. bad spark all or bad injections to all (lean) or engine cam out of time? P1 codes are factory only codes. Jag codes P1000 means car is not ready for smog tests, the , onboard readiness is not complete, means drive for a day or 2 and is caused by scan tool DTC reset or battery on car went dead or was disconnected. next P1316 _ Misfire Excess Emission, get the shop to find it. there are a battery of test to do. even low fuel pressure can trip p0300. goes lean ,combustion goes weak and BINGO gross misfire. or bad spare, but how can all fail and not get one cmp or ckp errors>? bad fuel> too. put diesel in the gas? park parked over 1 year or parked less, with 1/8 tank for long long months? we can not guess history of any car.

what in the world is a starting inhibitor? why not post a problem first, an end goal? what is failing or tell a goal . my wild wild guess is , a car alarm that blocks the stater motor ? that is a super old car. and will have vast $$$ problems is this an upgrade question? we sell no car parts here so there is no COST we only do free words in a text box here. 100% free the costs of all things are not the same on earth. so use google + buy to see those prices no goal or problem told. just nebular, starting inhibitor if need and alarm on the car (and blocks cranking) ask a shop in your town for help and or advice. in some towns USA there is a store called Car Toys I like that name but every town as place to install alarms. any major sized town. (parts and labor)

no by-pass or hotwiring system ---check key for excessive wear or damage as well as ignition cylinder ----have vehicle scanned for problem codes

Question edited for clarity. There are fuse boxes all over the place! https://www.manualsdir.com/manuals/132991/jaguar-xk8.html?page=24 More here. Strangely, the best fuse box sites don't list this model. https://www.google.com/search?q=2000+jaguar+xk8+fuse+box+diagram ..

Question edited for clarity, correct model name. This is a job that you can only try and see what happens. The most obvious is that the ECM will be managing and metering the fuel and engine management for a 2.5 engine and it is actually a 3.0 engine. This is born out in the link, so ECM swap as well preferably from the engine you are buying if secondhand. https://www.google.com/search?q=2003+Jaguar+X-Type.+What+issues+will+I+run+into+swapping+out+the+2.5+for+the+3.0+litre+engine ..
