XJ8 3.2 Fuel rail pressure
Just an update on my car not starting after replacing the fuel pump
it is not the cutoff switch
I could only get a push on tire pressure gauge
it showed 48psi when turning on ignition for a couple of seconds then dropped to 38psi probably not accurate its only a cheapie
I have read learned it is supposed to be 44psi,
anyhow at least there is fuel and a great spark as well.
so I've removed all spark plugs sure are dirty and a lot of oil around them when I took them out
I have attached 3 photos of them but unsure how to convert them
so I figure let it air out for a few hours its 30degC here, and thought I would put 10ml of oil into each before putting the plugs back
Not a nice colour ( new set required)
How does the oil get here
only gauge at auto part shop
not sure when I crank again to press the pedal to the floor or don't touch anything?
probably try not touching anything
any help would be good

Your fuel pressure is okay, but I would get rid of those autolite plugs and use NGK iridium, but plugs are a personal preference. The oil on the plugs indicates leaking seals, so replace the cam cover gaskets, and don't forget to use new seals for the screws.
As long as the plugs are out, put about a tsp. oil in each cylinder and hit the starter a couple of times with the pedal to the floor to distribute the oil and blow out the excess. Place rags over the plug holes to catch the spray. The engine will smoke when you start it.

#1 Second fuel pump (SC models only), #2 Rear window defroster, #3 Side marker, license plate and trailer rear lamps, #4 Fuel pump, #5 Stop lamps (HMSL and trailer only), #6 Accessory socket (where fitted), #7 Fuel filler flap lock, #8 Fuel filler flap unlock
So as per your and mine # 2 Fuel pump relay is missing from mine
#1 relay fuel pump relay (Actually referred as relay #4) is in its next to the 10amp(red fuse) and 20amp (yellow) fuse
Stop lamp relay is in mine and Accessory missing plus another one next to it
