how much fuel is in the tank? what fuel tank and pump are you running?
does it have a swirl pot?

i'd assume its fuel related personally..

Hi Dean,

Fuel tank full - no difference. Mine is a wagon. I have two high pressure pumps, both external. One at the rear on the arch of the sub frame close to the tank, the other up in the engine bay. Today I'm checking all electrical connections to see if there's anything loose - everything on top seems tight.

When you accelerate from stop, as soon as you touch the pedal the engine cutout occurs, then it clears and runs strongly. Wondered about vacuum advance or air intake box settings. This whole thing has just happened suddenly.

Cheers, SC

yeah if it has an air flow meter from an XF EFI it could well just be that.. they used to be troublesome(i say used to because most cars with them are extinct now) if you can find someone with one to trial theres, that would be a good thing to do.
there'd be minimal people that would know how to get around it i would bet these days also if so.. other than fitting EFi wiring from EB falcon(non smartlock if so.. even that will be probably getting hard to find soon)
