Chevy did not use a crankshaft sensor in 1995. If it won't fire then I would check the ignition module in the distributor and more then likey replace it. Also check the ignition coil and WIRE / coil wire.
red wire goes to positive battery white and black wires are for the light white wire being the positve and the green wire goes to the ignition control modtral on passenger side motor on the coil packs it goes to the white wire
Disconnect the cable at the battery. Trace the wire to the other end, looking at how it is routed. Disconnect the wire and pull out. Put the new wire in, routing in the same manner. Connect the cable ends back up.
