If you have power to everything and your grounds are good, I'd certainly swap out distributors and see if it runs. If it does I'd blame the mag pickups.

Finally got my new dizzy after purolator screwed up on shipping.$400 later I have it in there and still nothing.This truck is really pissing me off.Why would I have over 11VDC to all the ignitor parts but no spark?I thought it was the dizzy but that put me right back at square one again?What else is needed to make spark on these motors?

Maybe its your timing chain? J/K
Have you confirmed that you have power to the + on the coils? Rotor is in good condition? You didn't replace your dizzy due to a burnt fusible link, did you? Hopefully its just something simple that you have overlooked somewhere along the line...
Like Mark Twain said "It ain't what you don't know that gets you, it's what you do know that just ain't so"...
Good luck man.

Motor is in awesome shape.But I did replace every little thing in the ignition system.I did find something odd tho.Why would all 3 of my coils only getting 9.3 volts?Any ideas on the cause of voltage loss?I think this is my problem now.Especially with DLDFIS.I redid the grounds and new connectors everywhere and still 9.3 volts while the battery has 12.7.

Hey J9FD3S would a faulty ignition switch cause a 3 volt power loss?My stepdad seems to think that the ignition switch would be the cause.That or a bad ground but my grounds are as well.Ideas?

Ah, I see it's in a rotary powered B series truck, not a genuine REPU. That's a different story. I've done DLDIFIS in both. In the B series, the battery is in the engine bay. It's very easy and highly recommended to add a relay.
Yes, the ignition switch could very well be the cause of your low voltage problem. In the B2000 I worked on, the fuel pump and electric fan were also wired directly on the same circuit. Dumb... I hooked up two relays; one for ignition, one for the fan, and left the fuel pump on the ignition circuit. It was a facet so I figured it would be ok like that. Anyway, the bucksnort problems went away and it no longer loaded up at idle.
Add at least one relay specifically for the ignition and get back to us.
