No error code, die going 70 mph solved, dead fuel pump
I have a 2004 XJ8 with 80,000 miles. Yesterday, I was driving on interstate going 70 plus mph and approximately 2 miles from home. The Jag suddenly went in restriction performance and die with three to five seconds after the warning. That was enough time for me to pull to the right shoulder. I do have a code reader that specific designed for Jaguar for there was no code. Engine cranked but would not start. I checked every possible and potential loose wire in the engine bay. I checked every possible fuse to ECU to fuel system and none were blown. I had to tow the Jag home which cost $150.00. I hooked up a trickle charge since last night and tested the battery under load and it was in good condition.
I was completely puzzled since there was no error code. I am posting this so members might have the same issue when car stalled with no error code.
My intuition indicated engine it's not getting fuel. I sprayed starter fluid to air intake and the Jag immediately started and shut down. It always good to have spare used Jaguar parts .I have been accumulated fuel pump, throttle body, coils, air shocks, compressor, sensor etc. over last several years. I mainly was hoarding parts that well recorded to break down. (thanks to forum members)
Replace fuel pump was not that difficult. But it was a pain since the fuel tank was full. I had to stick my arm into the fuel tank to feed the fuel line to the sender unit. To my surprise, disconnect and connect fuel lines did not need special tool.
Disconnect battery
Remove rear bottom seat.
Remove two rubber caps.
Unplug harnesses from fuel and sender unit.
Unplug fuel line. (no special tool needed). Just press and pull.
I used rubber hammer and a flat chisel to unscrew the two lock rings that hold the fuel pump and sender unit.
Remember to mark orientation of fuel pump and sender unit with marker before removal.
Disconnected fuel lines from pump to sender unit. No special tool needed , just press and pull hose apart.
Removed fuel pump unit.
Replace with good working fuel unit.
I used a rope, feed from the sender unit tank side to the the fuel pump tank side.
I tied rope to fuel lines and pull the fuel lines from fuel pump side to Sender side.
The remaining procedures were just reverse order.
I re-used same sender unit and only replace fuel pump.
And voila, car started.

I replaced the entire fuel system and not just the fuel pump. However, I will disassemble the old fuel housing and will find out the fuel pump specification. All fuel pumps listed on Ebay from China are junks. Don't waste your time. Only buy well known brand name. I am in track car as hobby. Chinese fuel pumps don't last.

Annamiata, I assume you could not hear the bad pump run when you turned on the key?
Mine (same car) sits in the winter. It would not pump when very cold. OK when it warmed up. Until this spring, now nothing. Even when warm. No codes, no noise from pump. I guess it is bad. Almost 20 years, so I guess it is time. Thanks for the info.
