I think I have a similar problem. Since buying my car a few years ago there's been an immediate high-pitched screech on starting (thankfully muffled) from the rear seat behind me, which settles down to a disgruntled mumbling. It didn't seem to cause any problems, so I haven't pursued it, but now I suspect it's causing fuel starvation when under sustained heavy load. It can manage about 2.5 gal/hr but not 3. (40mph @ 13mpg -- starts to die after about a minute). Seeing as it drives well otherwise, and hasn't got worse, do you think it is likely to be the pump or the control unit? @Vanthrax01 Is your spare fuel pump still available? I will be driving to Bedford in a week or so.
