Where is the fuel pressure regulator located?
I think my FPR is pushing too much fuel into the car under cold start-up. This makes a strong fuel smell that goes away in a few minutes when the car warms up. It seems to also happen under repeated heavy acceleration. Where is it located in the engine area?
Anyone else have the same issue?
Thanks.

You might like to read the fuel trims.
I doubt it's anything remotely like what you've guessed.
Is it definitely a fuel smell or exhaust smell? Also, where do you smell it? If in the cabin, how (where) is it coming in? You may need a passenger to sniff as you boot it and get them to sit in front and back.
edit: if you like, you could read the actual fuel pressure and compare with the car's fuel pressure sensor. I'd pursue the leak instead

A possible suggestion is to start on the passengers side of the engine. Gently pull up the portion of the wiring loom that sits over the rocker box and next to the S/C cooler tank. This will give you much better line of sight to the fuel rail.
With the engine ticking over look at the mushroom headed protrusion that hangs down from the fuel rail. There is a high probability that this is leaking and running back down the engine and dripping out onto the bell-housing before evaporating.
As this is close to the intake for the HVAC system the smell of raw fuel is more prominent and your symptoms indicate a leak in this area to me. If this is a recent event there may not be any codes set but worth checking for any in pending.
As always with any fuel leak take safety seriously and be cautious searching to resolve it quickly
I hope this is possibly of some assistance.

I have a 2000 vondon plus 4.0 with 62000 mils. That i inherited so I am new to the jaguar. The car set in my mother-in-law‘s garage for over a year not being used the car cranked up fine I drove it home which was a 3 Hour Dr. when I got it home I changed the fuel filter. The fuel that came out was black. I purged the fuel system until clear fuel started coming out After refueling and added seafoam fuel cleaner, the car runs perfect and normal city driving but when hard acceleration occurs to check engine light come on with a code of P 1000 along with reduced performance and the car stumbles had the fuel pressure checked and confirmed OK When analyzer connected to car it was found to be running lean no other codes or problems noted any ideas ? Thank you

First P1000 only indicates that someone has cleared the codes which also resets the readiness monitors. Your will always have either P1000 or P1111. The P1111 code indicates that the readiness monitors have been set and the car is ready for inspection. So neither of those codes help with troubleshooting.
You most likely don't have a code reader that works very well on Jaguar's? What code reader are you using?
Again post what the fuel pressure is? Post what lean code your getting?
One thing that stands out is the car has been sitting for multiple years? Plus the car is now approaching 25 years old. It's common for fuel pumps to need replacing in these conditions. Good that you changed the filter.

Lots of codes are required to flag only if they occur in similar situations during 2 warm ups. A code clear restarts the 2 so don't be clearing any! (And you can't clear P1000 as it's a status not a code.)
