Sometimes the D or drive light flashes while car is in park, not started but when trying to start it cranks but won't turn over, already replaced distributor, but what in the heck does the D or drive light for the gear shift have to do with the car not starting??

Da same thing happen with my 1993 honda accord , but I think is something that has to do with da transmission like a fuse or something on da transmission

Check for transmission codes.
