Never owned one but maybe your car is Vapor locked...It's when your gas tank pressure becomes greater than your fuel pump..It's caused from years of over filling your gas tank...Your car is designed to burn vapors. But gas goes down the line instead and clogs up your canister meant to filter fumes...Then it builds pressure up in the gas tank. When the pressure in your tank becomes greater than your car...It shuts off and want start back until the pressure has gone down...If this is the problem just loosen your gas cap...it releases the pressure immediately...You usually will hear a suction sound when you open your gas cap....Hope this helps...It could be the problem...maybe not...But something you might not think about or know

Hello Did you check the fuel pressure

check if your car has a speed sensor located in the diff rear cover if so from memory early face lift xj40 models used that sensor for the cruise only signal . the speedo signal came from the abs circuit. does the speedo fail at the same time? the sensor in the diff used to change spec when the oil increased in temp whatever sounds like the speed signal is at fault, blue wire i think at the seed control module good luck

you don't have all the air out of the system yet, or you have a bad master cyl

I buy a lot of parts from rockauto.com and also try jaguarspecialties.com! I check both for price comparisons

Hi,
The fuel filter is located under the car, in front and in a little, from the L/H rear wheel.
