Enriched isotopic abundance ratios of ^30Si/^28Si in several presolar SiC and graphite grains qualitatively indicate oxygen-neon (ONe) nova origins but fall short of ONe nova model predictions by factors of 20-90. The ^30P(p,γ)^31 S reaction rate uncertainty in ONe novae spans four orders of magnitude through which the predicted amount of ejected ^30 Si can vary by a factor of 100. By measuring the ^31P(^3He,t)^31S^*(p)^30P reaction we have determined the energies of astrophysically relevant ^31S excited states to ± 3 keV, and have found one new resonance. Proton branching ratios have been constrained by detecting decay protons in coincidence with tritons. Implications for the ^30P(p,γ)^31S reaction rate, ^30Si production, and S-Ca production in ONe novae will be presented.
