How dirty is the base of the dist.? The hold down clamp, base, and intake where the clamp touches have to be spotlessly clean or there wont be a good ground path for the module. For that matter, poor grounding at the block will also cause problems. Ive had both of these problems before.

Hate to say it but this is really pushing the rules of the forum.

Take the 2 wire connector from the distributer to the coil off on both ends. Ohm the each wire while flexing the wires. I bet you find a break in the wire.

Another test is to crank teh engine and see if the fuel pump/injectors come on. if so, you can immediatly rule out the pickup and probably the module.
