I fired a fresh motor tonight only to have a rattle trap of a valve train. Noise didnt go away after a few minutes so I pulled a valve cover and poped the distributor cap. Bumped the pointer around and re adjusted all the rockers, put the cover back on, cranked the motor and no spark. Well my dumbazz forgot to screw down the cap and broke the pointer off by accident. I put a new pointer on put everything back together exactly how it was marked before I fired the engine, cranked it over and still have no spark. WTF!?!
Yes, the coil wire is attached.

Could be the distributor sensor. Strange as it sounds, I had one go bad in an instant a couple years ago.
This should help, there is a troubleshooting flowchart toward the back. I used to have one for the TB IV but can't find it at present...

The trouble shoot chart above will direct you right to the problem.. I change them frequently. The new ones have a separate ground lead. They can stop working for no apparent treason.
When you remove the rotor and sensor wheel you typically need to pry up with a screw driver.. Any metal to contact the sensor pickup will damage it. Be extra careful not to touch it with anything but your fingers.

Thanks guys, I probably hit it by accident while rooting around with a screw driver.

On another note, I've never time a TBV (only TBIV's) and need to do one tomorrow. According to the manual I need to ground the Pur/Whi wire to put it in Base mode, so then I just set the timing straight up at 0? That's what it looks like in the book...

New sensor did the trick. The new ones are a hell of a lot faster to change. Cheaper too.

TDC Top dead center for timing what kind of motor?
