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.
Those spark plugs seem well overdue for replacement. Just to mention two things: the gaps appear too be way too large (at least looking at the pics) and the brown stains at the joint between the ceramic insulator and the metal "hex" mean that the plugs have done a lot of mileage.
I have come across that a few times in my searches but was unsure as to it being for the XK8 4.0 aj27 engine
some other references have been
AJ84575

PFR5G11E
BKR5EVXA-13
all in all I think to go with the BKR5EIX-11 @ 1.1mm gap
Thanks for your time Dutchy
Now w/ my base 4.0 only having 1 fuel pump the diagram shows 2 relays, are both active w/ the singular pump option ?!
KC, I don't think so, if you look at your trunk fuse box I think you will find that the relay #1 location is empty, as per this diagram per Lady Penelope.
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
I have uploaded a workshop Manuel for my XJ8 the link is at the top of the forums (threads under sticy's name you look across and will see Dutchy but here's the link anyway, also a lot of info is avaible from quick links took me a while to find it. https://drive.google.com/open?id=1VS...QGS7_bTuCvpzYq
