could be related if condensation is on inside of windshield indicates heater core is leaking in heater box under dash on pass side car may be over heating check coolant level, coolant fan, and thermostat if working, also keep eye on temp gage if equiped

Of course you realize that the pressure fluctuates according to your acceleration right? If it's going lower than it normally did than there can be a compression problem with the engine or possibly the oil pump is putting out a low output.

If you put your AC on, and you get hot air instead of cold, you are likely out of Freon. You can buy it and fill it up yourself or you can take it to a car shop.

As far as condensation, you mean in cold weather right? After you drive after a while, your car is hot, and if your vents dont completely close, that hot air will go into your car. Thats a problem with your air vents, they're either not closing completely or the seals are bad.

I hope this helps you

it is located againts the inside fire wall above where your left foot sit towards the top you have to feel for it. its hard to see

Check fuse for the fuel pump in the pasenger side fuse box and lift the relay off of the bracket it could be shorting it out

first of all you have to have the car up on jake stands or ramps and take the nuts are bolts off the straps and then take a floor jake and a small board so you do not put a hole in your gas tank and then low the tank down and take a hammer and a good size screw driver and lose the center ring and then you have you pump out also be careful not to break the wires on the top of your tank when you low it down

Hi irvj6ohn:
The 1993 and 1994 XJ6 Fuel Pump Relay is located in the trunk of the vehicle on the right hand rear side. It is light blue and black in color.
I hope this helps.

First and foremost I would demand the dealer to access the situation since I assume you paid them to fix the problem. This sounds like an electronic issue between the transmission and the idle switch. When you brake with an auto transmission it downshifts thus adjusting the rpms to compensate. If this is malfunctioning it could very well stall it..

its not the computer its the wiring going to ur fuel pump relay once the get warm they will ground out run a new wire and make a power jumper

Generally speaking if a EFI car wont start but will "turn over" there are many points in the fuel system that could be hindering the process. I would start with the fuel filter. Also if when you begin to turn the ignition on you should be able to hear a light humming noise (this is your fuel pump engaging). If you dont hear this humming it could mean a bad fuel pump. A temporary fix is to take a none abrasive or punctioning object and tap on the fuel tank... Fuel relay would have to be checked electronically...like the previous poster stated...

a person can take two jumper wires and bybass your relay by going straight to the pump. in return if your motor will start then the relay is bad. also by doing this you are testing the wiring as well due to the fact that if you bypass the relay and it starts then you know that the wiring is carring the juice needed and that the relay is out. however if you bypass it and it still doesnt start try using a seperate car batter as a power source and put your jumpers on there. if it starts that way then it means that maybe you have an electrical isue. but when you do it with the other battery try it before the relay and then with out the relay this should confirm the situation. also you can take a voltmeter and check the continuity befor and after the relay to determin how many volts your getting there, if its going though the relay, or if you are even gettin power that far.

its on the main power supply board.
and there are 2 fuses.
thanks

93 Jaguar XJ6, sadly the pump is located in the gas tank and the tank has to be removed from the trunk to gain access
Pretty basic replacement except above the rear axle underneath the car are where the fuel lines are connected, they are quick connects and are help in place with a spring pin, do not remove the spring pins, you just turn the pins to one side and the hoses will pull off, but you will need a rack to do this, It is impossible to get to the hoses with the car on the ground.
The tank itself is self is pretty easy, just be careful when you remove the screws holding the fuel filler gater assy as you can tear the rubber and they are expensive to replace.
Hope this helps

im sure the oxy sensor is because the right bank is not running first you need to see if you are getting spark on the right side,
what im thinking is if you have spark you have a cam that has jumped and you could do a compression test to check.
lets check spark first
later

i have a 92 xj6 i just replaced the fuel pump should be the same for yours remove spare tire in trunk there are two straps two bolts take bolts out jack car up there are locate your fuel filter mine was under the rear door drivers side follow the hoses and they will lead you to the two hoses connecting the gas tank there are two pins to remove one on each hose do not loose those trust me they will be hard to find and be aware there is very little space to work in after removing tank the rest is easy remove the pump located in the tank and do everything in reverse also dont forget to replace the screen to clean all the rust out of the tank there is a bolt in the bottom of the tank to let all the debris out good luck

fuel fiter is dirty

The started is located on the left rear corner of the engine, ontop of the car, not underneath.
If you look in the engine bay down ontop of the transmission on the elft rear corner you can see it.
I do not suggest hitting it with a hammer, most of these started now have plastic gears unlike the older ones.
Usually it wont come to life by hitting it.

It is a fuse that is out.
