It sounds like you may have a defective distributor, here are the wiring diagrams for the distributor so you can see how the system works. And white wire goes to a condenser noise suppressor so it should not matter. The engine wiring diagrams included the ignition distributor BTW.

Here is a guide to help you test the wiring:

Okay Ken, so with that being said about the distributor I've got throwaway distributors whatever you want to call it but I've changed all the parts in them and I've got several pieces and I've interchanged everything what's happening now is what's happening is the fuse on the inside of the car for the ECM is not there's no power going to it and yesterday when I checked the wiring on the plug for the distributor the six pin I mean six the black and white wire there's no power to that wire and there's still no power to I think the crank sensor wired I'm not sure I'll have to check that but that's my answer that's my reply right now I appreciate it the getting back and I'll be looking forward to your next thing I'm concerned about the fuse on the inside of the car fuse box everything else every other fuse under the hood inside the car lights that that went on inside the ECU has no power.
