I have a fuel issue with my 2000 XJ sport. It has trouble starting when I initially turn the key. I have been manually priming the fuel pump by turning the key to the on position a few times for a couple of seconds before I start it up. I don't believe it is the fuel pump because once started, it runs like a champ. I've got a feeling i'm losing pressure in the system whenever i turn it off. Anyone ever experience anything like this? I'm planning on dropping the fuel tank and replacing the filter and some other components. How hard is it to drop the tank? Any input is appreciated.

Check your fuel pressure regulator. I don't remember exactly if it is on the fuel rail or tank. If it is on the rail it will at the front of your fuel rail and has a vacuum hose attached to it. If it is in the tank its part of the fuel pump and you gotta change the whole thing. BEST OF LUCK.
