It doesn't go till you floor it??? might not be the pump...that could be a number of things. be good to know what engine (zetec(4) or Duratec(6)) and atx or mtx. Also what mods, mileage, and maintance done to it.
It could be that injectors are crap or are clogged. that would cause a lack of gas until the pressure built up enough to escape. You may even be due for plugs(poor ignite = lots of unburnt gas). Thats my $0.02. I'm sure some other guys can chime in.
Edit:
Sorry didn't look at Sig, all info is there.
oh by the way you don't have a CEL do you?
