Friend just picked up a mint low mileage S type 3.0, 2002 with
106000km on the clock. It needs brakes, but before getting into that
it has another issue. It starts perfectly, then after a few seconds of
running the CEL flashes, it runs rough, and gives message it is
running at reduced power. Code P0300 comes up. Is this likely to be a
cam sensor problem? (disconnecting both makes NO difference - which
makes me suspicious) or a fuel pressure problem? (is there a schrader
valve on an 02 where I can connect the pressure tester - if so where?)
I've done some work on old Jags - e types and MkIIs and old XJs - but
out of the loop on the new high-tech Jags. Looks a lot like (my old)
Mystique 2.5 and Taurus 3.0 18 valve engines but totally different
ignition and fuel systems.

I don't have a suggestion for the repair but have a hint.
There is a website/forum for the Ford/Lincoln LS, which is basically the
same as the Jaguar S-Type. Sheet metal is different but it appears the
engine, drivetrain, suspension and most everything else is all Jag.
https://www.lincolnvscadillac.com/forum/forums/lincoln-ls.7/
There is also a section for servicing, including some manuals.
I beleive yours would be the same as a Gen 1, six cylinder.
There are a few regulars on there that seem to eat, drink and know pretty
much everything to know about the LS. They may be able to suggest a starting
point.
I don't want to mislead you but the fuel pump is a likely suspect, I've seen
enough posts about replacing it where it looks like it's something that
doesn't last the life of the rest of the car.
Good luck.
