Bulkhead pins had grease on the tips, cleaned , reassembled along with every connection under dash , no change , no start . Is there anything under the seats or passenger footwell electric connections that would cause this ? Next I'll check into neutral safety switchAccording to the manuf. spec sheet for dielectric grease, it is not advised to use directly on low tension/clamping connectors, only on larger points such as starter cables-to-starter. In your example, the manuf. suggests coating the mating surfaces where the shell on one slides over/outside the other...the idea is to create a moisture barrier, discouraging moisture from reaching the pins.
