[xj-s] Growling Fuel Pump.'93 4.0 Convertible

XJ-S
1

The XJS developed a growling from the trunk on twisty roads in the
mountains at 9,000 feet altitude. The sound was such that I thought
it was from the diesel engine of a pickup truck behind me but it
continued after the truck was gone.

After sitting for an hour the sound resumed as I continued my
drive, getting no louder or softer.

There was no loss of power or other symptoms (like flames leaping
out of the trunk!)

Because it is a Jaguar of course the next day the sound was gone!

Is this a warning sound from the car that it wants a new Fuel pump
( after 120,000 miles?) or just ‘‘one of those things…’’?–

Paul,

I agree with your thought it’s the fuel pump. Should be easy to check when making noise. When holding the pump you should feel the sound vibration.

submerged in the tank :wink:

Ok, hold the tank or press your ear up to it!

Thanks for catching my error.
