Problem fixed: No oil pressure indicated, not starting, no alarm.

This was difficult to diagnose because of the many components involved. There is a slave solinoid near the distributor, an oil pressure warning switch almost under the distributor, an oil pressure studown switch next to the oil pressure sending unit located on a fitting with the oil pressure sending unit above the oil filter. In my case, the slave solinoid had become weak so there was intermitent action when turning the key to the start position, but it also interfered with the gauges an alarm. The oil pressure switch wasn't allowing the ignition to fire. Once the components were replaced, the engine fired right up.
