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

Per 67Dart273, there is a test of the ECU; I forgot all about that.

You can check the standaed ECU's response to the reluctor by disconnecting the 2 wire harness to the distributor and momentarily grounding one lead to the ECU and then the other while looking for spark. One or the other should produce a spark each time it is grounded/ungrounded. If grounding either of the distibutor pis to the ECU never produces a spark with everything else hooked up, then the ECU is bad for sure.

I think he snapped a photo right when it sparked when disconnecting power to the system.
