I did not see a response to the type of ballast if its a dual sided ballast go to store pick one up, stop and get beer on way home replace ballast open beer turn key and listen to car run. on dual ballast one side handles start one handles run, start side goes bad = "crank" position on key spark will not be there but run position will be = no start with a possible spark witnessed when key returned to run position. run side goes bad= key in crank position it sparks engine fires then stalls as key is returned to run position due to no spark because of run side ballast issue. not looking to start issue but lots of time and money spent chasing ballast problems over the years by many. If it doesn't fix it I would then check bulk head connections steering column connections then triple check the new wiring but who am I anyway. I hope your drinking a beer listening to her run soon..stay at it
