The prototype nova-like variable VY Sculptoris was observed by the IUE during four different optical brightness states of the system .
The FUV flux level from the highest state to the lowest state declines by a factor of 28 .
We have carried out model accretion disk and white dwarf atmosphere fitting to the spectra .
The corresponding accretion rates range from \dot { M } = 8 \times 10 ^ { -9 } M _ { \sun } yr ^ { -1 } at the highest FUV flux level down to \dot { M } = 1.9 \times 10 ^ { -10 } M _ { \sun } yr ^ { -1 } at the lowest flux level .
We report tentative evidence for the detection of the underlying white dwarf with T _ { eff } = 45 , 000 K in the spectrum with the lowest flux level .
