SOURCE: changing rear shocks on a 1990 jag

No. But if can't get it on a lift or high enough to work under comfortably..it will be very awkward. The calipers get in the way when you are removing the springs and shocks as a unit. You can move the part and get it out and down, but you will need to remove the rear wheels and let the rear springs hang down.
Make sure you have a good spring compressor to get the old springs off....in most cases it is the springs that go soft and not the shocks...
Don't assume that it is the shocks unless you know for sure they are bad.

SOURCE: where is fuil pump in

The fuel pump is usually located in/on the fuel tank, but with your jag, it is mounted externally from the tank. Frame mounted design with an inlet and outlet fitting...

Jack up the rear left hand side. Put the car on axle stands. Remove the left hand rear wheel.

You should be able to follow fuel line back to the fuel filter (just forward of the wheel arch) and then to the fuel pump which is behind wheel arch, (before the rear silencer/muffler).

One thing though, you might just have a faulty fuel pump relay, which on your 1990 can be found in the engine bay, left side, attached to the brake pedal hanger.

If you do decide to remove the fuel pump after all, then depressurize the fuel system first.

Remove fuel filler cap, disconnect the fuel pump relay, start engine and wait for it to stall. Turn off ignition, then disconnect battery.

Take all the usual precautions before disconnecting fuel lines, rags, container to catch spilt fuel etc.

Hope that helps, please rate me too thanks!

I HAVE A JAGUAR XJ6 3.2 1994 , AN NEED THE IGNICION AMPLIFIER CIRCUIT, IS MY FAIL I THE COMPUTER CAR FAIL 24, SORRY FOR MY ENGLISH


Typically code 24 is reserved for the ecu to ignition amplifier. Recheck your fault code by just switching the ignition to "on", wait 5 seconds, then re-check your code(s). Code 24 is uncommon, and very few people have documented this

Other possibilitie is the ignition amplifier is bad or the connection is corroded. The part is easy to get to, and is easily replaceable, but I would not suggest trying to test it yourself unless you know how to use a voltmeter.

If you want to replace it I would first buy a Haynes manual and follow the instructions (they have pictures).

Check additional details in the Jaguar Online Manual in this link: jag-lovers.org/ebooks-index; check the section 10 Engine >> 10.14 Ignition amplifier module (need to register for free).

Also, check this interesting info AJ6 4.0L Engine Management System Diagnostic Guide (pdf format).

Hope this helps; keep us updated.

Replaced the ignition amplifier and coil and purchased new computer for 1990 Jaguar XJ6 and the car still does not want to start. First I had no fuel now I seem to have to much fuel.


You can't clean a CPS, it is either bad or good. Replace it. Also, if there was any water in that gas tank you can crank it till the cows come home.

Possibile ignition control module problem Check for spark when problem occurs No spark.. Follow wires from distributor to icm box. Open box and you will find a gerneral motors ignition module. Remove module and have tested at local parts store. Replace if bad. Jaguar wants over $300.00 for IGNITION AMPLIFIER UNIT. You should get gm module for under 50 bucks.
