XJ8 Fuel Cut off switch
I'm picking up a wrecked 1998 XJ8 L on Friday. The car starts for a second then shuts off. I think there is a fuel cutoff switch that tripped in the accident. There is no manual in the car, so I can't look it up that way... I searched all over here and the internet and couldn't find any hints.
So... Can anyone tell me where the fuel cutoff switch may be? Any other reasons why it would instantly shut off that I can reset just to get the car onto the trailer?
Thanks for any help!!

RE: XJ8 Fuel Cut off switch
Thanks guys. It's my brothers car (long story there) but he did say it's really low on gas as well. He's going to add a couple gallons and check the fuel pump switch.
It will make it a million times easier to get the car on the trailer if it will run for 5 minutes...
Thanks again!

I have the same problem with my 99 xj8. I just replaced the fuel pump, I'm thinking maybe there is a safety that shut the switch off? I had a "failsafe" message on the dash, not there anymore though.

I would think no
the engine may fire due to leftover fuel in the cylinders
the inertia SW stops the ignition (spark) as well I believe and the fuel pump
so if you turn on the ignition you should be able to hear the pump run in the tank (boot access) or remove the cap if there is not much fuel you may hear the pump
you can also bypass the pump relay by jumping the switch contacts of the relay
my XJ8 kick but won't run plenty of fuel plenty of spark new fuel pump and with the help of the forum we are down to maybe a flooded engine the fpr replacement next
there's also the WOT (foot to floor) to clear out any excess fuel
anyway I wish you luck

I installed 2 fuel pumps on Jaguar XJR 2000. I might have bent the fuel line or return under the tank. The car runs now but shuts off after approx 30 seconds. I did not remove the tank completely. Could this be the cause of the performance and whats the best way to fix it without removing the tank completely? Thanks

Hi Naresh
I am not sure if your car/tank is the same as my XJ8 1998
but I removed the tank just enough to get my arm in the top and get the pump out, and new one in
Then when I pushed the tank back it kinked the fuel line supply.
so I disconnected it from the filter
pulled the tank 1/2 way out again and used a pipe cutter tool to cut it off about 2" long
then brought some high-pressure fule rubber hose and 2 clamps
connected the tank first put it back
then under the car, I had also cut off a 2" piece from the filter nut and then joined it all together
tucked it up away from exhaust and cable tied it
this was just to try and get the car going But if you don't mind not genuine its seems fine.
I am downloading a video for you
I will send a like soon
