On the 95 I beleive there is a connector near the fuse/relay box that is the plug for the solenoid wire to the relay wire. You could put a volt meter in the relay side of the plug and wiggle the shifter around a bit and try a few gears and check for low voltage or intermittant power loss. The NSS, like the relay could be an iffy thing, sometimes and sometimes not making good contact (I once found a bad solenoid wire, that had fatigued almost completely through from vibration). But most times, when the solenoid clicks and the starter don´t turn, the brushes (either oil soaked, mud covered or worn) were the cause of the problem. Really not that big of a deal, to take the starter off, mark the case for reassembly and pop the back cover off and look at the brushes. If your oil filter mount is leaking, it could be as simple as oil on the brushes and a squirt or two of brake cleaner will get things working right again. Takes two people and some patience, to push the brushes back into there holder and put the rear cover back on.
