    Too much pressure, yes. Should be 42 psi. I don't know this car at all, so I'm in the dark here. There IS a sealing ring for the evaporative loss flange at the tank.

  • I need a free download manual, for a 1990 Sovereign. Scope of service work requires exact info and pics, tired of slow dancing. I know there's a Haynes or Chilton out there, I got it and deleted it cause it was a lot on my computer.

    you can buy one used for $8 bucks. Surely your baby is worth that? :P

    used Haynes Manual for Jaguar on Amazon

  • There is no question but that the early 90's Jags had lots of fuel supply, and consequent starting problems. I have been there (with a 92, XJ6). But, there is one possible fix that has worked for me a couple of times, when I thought I had a fuel starvation problem, and the engine would not hit a lick. Try re-setting the Computer. Disconnect the + battery side for 10 min. or so. Turn on the switch, then reconnect. Leave the switch on and disconnect the battery again. Turn off the switch. Re-connect and see it she won't crank up.

    You may be getting fuel to the fuel manifold, but not past the injectors, if the computer is off-base (or shot).

  • I have an 84 XJS HE that has a fuel leak on the pressure side just after coming out of the pump on the wheel well side. A rubber hose is situated between the differential saddle and the frame. Does any one know how to replace this hose without having to remove the saddle?
  • @nancyisenberg said: I purchased what appears to be an inline fuel filter for my 1999 Jaguar XJ8. The parts place says it's located under the car on the drivers side, nope, Jaguar says it's in front of the drivers side wheel well nope, anybody replace the fuel filter. Looked in the truck and under the back seat no luck. Car won't kick over but does crank. Suggestion? @redrocketman said: Just found this forum and interested to see the same problem that I am facing. I have a 2002 XJ8 which cranks but won't fire and I suspect fuel starvation. I can't seem to locate a workshop manual for the car and would love to know where to find the fuel filter, fuel pump and fuel reset (if there is one). Does anyone know where these items are located, or any other likely cause of this problem? Also, does anyone know of an aftermarket workshop manual published for these cars? Thanks

  • what is the answer

    On the 1999 XJ8 sedan the Fuel Filter is located along the frame rail, next to the fuel tank, and near the driver side rear wheel.

    On the 2002 XJ8, same place.

    A 'no start' condition can be caused by many things--it would be a long list. First thing you can do is have the car scanned for trouble codes---sometimes chain stores like autozone or OReilly will do this for you for free.

    Also, here's a CHECKLIST of things you or your mechanic can look at:
