Car Starts in Gear

Im baffled because I can Wire the factory NNS as schematics show and I can start in any gear. The original shifter had a reverse light switch built in. Got that covered. So I,m wondering if the new NNS i bought is no good or not. I rebuilt the trans and the rooster comb was good and correct. having the same fun with an aftermarket fuel sending unit.

Thanks,Tim
