This video shows (more or less) how to replace the fuel pump on a Jaguar XK8. My car is a 2003, which has a slightly different fuel system than the 2002 and …

Must’ve been the camera man @ 4:32 hahah. Thanks for the effort and solid instruction, Sam!
It is a 99 XK8. I hadn’t started it for several months. I also have a
problem with it going into Limp Home Mode ocassionally. The readout says it is a coil. #3B I think. Do you know which bank ia A and which cylinder is #1 (front/rear)?
Thanks for the info!

You can unplug the connector which powers the pump and apply 12 volts from the battery straight to the pins in the connector. If you hear the pump running then you can assume the problem isn’t the pump.
What year is your car? The design of the fuel system changed in 2003. If you’ll tell me what year it is I’ll look up the connector and pin numbers. for the 2003+ cars the connector is in the trunk on the front wall of the trunk towards the bottom right.
How do you tell if the problem is the pressure sensor or the pump?
thanks
Great Job! Have not had to do this yet, and hope I don’t. But good to know this is here.
2001 XKR, I had a guy replace my fuel pumps (2) last week. When I went ot pick up the car now I have a suspension fault. I never had suspension fault until pumps were replaced. the 2001 has the CAT system. have you ever heard of this situation? I read another guy on internet with same car had same scenario. But never posted fix?
The pipe thing is cool but.. Hopefully ill patent my idea of the tool… I just use the white little fuel disconnect tool and push it in with the 3/8 extension that is long enough…
1:18 you did alot of unnecessary steps… With the fuel bowl and actuator…
Used your video to replace my fuel pump today.
Thanks a ton.
My wire harness to the pump was actually melted. WHen the pump starts to go, it pulls too much currant and melts the wire. The plug fell apart in my hand. Jag wants $250 for a new float/sender assembly (it’s attached to the melted wire). I’m just going to splice, and heat shrink the wires.
I also found that if you just pull the tank straight back, it gives you plenty of room to work.
Thanks for the info. See you back at Jag Forums
It is probably the fuel pressure sensor. The ECU regulates the fuel pressure by pulsing the fuel pump on and off. Normal fuel pressure is about 55 PSI. If the fuel pressure sensor is constantly telling the ECU that the pressure is too high, then the ECU will never tell the pump to turn on and you’ll have no fuel pressure.
Hi Sam
I have a friends 2003 XK8 the issue is it cranks but will not start i have fuel (pump 1 year old)& spark.
I do have code PO193 Pressure Sensor Voltage Hi.
On the scaner the ragulator is stuck at 70PSI no matter if i’m cranking or not.
I will order a new sensor today,let me know if you think of anything other then the pressure sensor.
Very nice video.
Thanks

Excellent instructions!!! Having convinced myself that the check valve on the fuel pump in my ’03 XK8 was leaking, I decided to follow your video directions. Sure enough, the check valve “ears” were damaged and it was halfway out. The two most difficult steps were getting the fuel line to release from the tank (made a tool similar to yours), and plugging the fuel line back into the tank – it’s hard to get leverage in such a tight spot. You saved me a bundle of cash! Thanks again!
Your my hero Sam! I too had to make a few tools. I found that if you leave more plastic to go around the 10mm line more (like 3/4 of the way around) it worked like a charm. You have to snap it over the line with a bit of force.
You saved me atleast $1600 on my 2004 XKR, I had a similiar problem where a plastic piece on top of the fuel pump had come apart due to a broken clip. Wired it up like you did and Walla!
Thank you Sam and God Bless!
I need help with a 2002 jaguar fuel pump replacement
This is very helpful. I am sure I am developing this same problem with my 2002 XJR. Is the check valve the same when this car has the return line? I have a 2003 XKR that had the brake switch problem. I followed your instructions and went to the link that you posted. I found a way to position the the switch with out much trouble. I would like to add my suggestion for others that have to do this job but I don’t know how to do it. Your video it just great! Ernie Jenson
