I have a suggestion for you to pursue.
This is not specific to your Jag, but any car with the
symptoms you described. When the engine starts it needs
the battery to crank the starter motor and to power the ignition system. Once it's running, the alternator provides
the power to run everything. If the battery is weak and
only good enough to get things started, but the alternator
is not powering the system, the weak battery dies within
seconds as the ignition system drains it down.
( Thus - the ignition dies.) Put a volt meter across your
battery terminals while cranking & with engine running.
If it doesn't read over 12 volts ( engine running ) you
might look into a charging system problem!
That would also explain the weak battery - no charging.
Otherwise, suspect a bad fuel pump. I've had new
replacements fail on me right away. Some auto parts
are just poor quality and don't last. How to know?

If you are not competent to adjust the fan belt, a local garage or mechanic can do that for a small fee. Probably wise to fit a new belt at the same time, being an older model.

Have you checked the starter motor ? Is there a good bond between the body and chassis metal parts? Determine if a fuse for the starter relay has blown.

I unlocked my gas cap also by using the key in the drivers door and unlocked the whole system. I hope it works for you.

Hi Marek,
I presume that you are asking what this code means. Also, I think that you have missed "p" out of the code. Try searching online for "error code p1646 jaguar x-type". You'll find hits on a number of sites. You are going to have to trawl through them. The main one is:
