No spark and i can only get 5V at the coil.

Sorry I had it disconnected in the photo. No you want power hooked up, and then ground / unground the indicated distributor terminal

"On a side note," you can also use the Mopar ECU with points, IE convert to a points fired electronic ignition by hooking the points to that terminal. This does not work with the GM HEI, LOL

Make darn sure the ECU is actually grounded
