you may try adding a engine oil flush follow the instructions on the container if the lifter is blocked that may help but that engine at that model/year suffered with worn nicosyl coated liners which made the engine poor starting/noisy unless it has been reworked with cast liners

Is it the PSI specs good {30PSI?} If not u have to start w checking 4 vacuum leaks, oxygen sensors, get emissions test to get all other emissions read (HC, NOX, CO) All the readings will give the tech a path. U have to have the right amt of fuel going into the pump & regulator to get the right PSI too. Clogged exhaust? The possibilities go on. Good Luck

Could at either plug(corrosion) Most wires break close to the plug, Check voltage a couple inches back. Unplug it(if you haven't already) check it. If you have voltage at the brake switch and a couple inches back(probe the wire) nothing at the Shifter solenoid. I would run a new wire to it. Way easier than removing the console and dash to find the short. If you have other problem, I would be looking at the fuse panel .

the age of your car suggests a throttle body problem. the the logged fault codes i think will confirm this

Possible bad wire in motor so it opens up and stops motor after heating.

Are you sure it is the coolant light? The coolant system is a sealed unit and should not need topping up unless there is a leak!

the cause of this is the pollen / cabin filter, renew it and it will cure the problem

I understand they are not adjustable in the normal sense and are self leveling via a servo motor that determines the ride attitude and moves the lights accordingly. Find a jag owners forum as to what to do next.

As i understand your quest you cant open the doors? Can you open the back trunk? If so you can disassamble the back seat wall and enter this way to the car. Post back.

Is the check engine light displayed? If it is, that's where you start, by retrieving the fault code(s). If not, then you could have a security system fault, fuel system breakdown, etc. All codes, regardless of the systems affected, will cause the vehicle computer to immediately default to a failsafe mode, till the problem has been fixed, and this drastically affects driveability, causing no-start issues, idle problems, etc.

I believe one one more of your drive belts, eg alternator or A/C, needs tightening.
