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

The thing is his wiring IS AFU. And in my experience, a bad ECU has been RARELY the problem in a failed Mopar ignition. In my experience the problems have been

Bad ballast

Bad connections at the distributor pickup

Bad distributor pickup or strike damage on the reluctor (usually worn distributor)

Misc wiring problems usually bad connections AT CONNECTORS

and last.................a bad ECU

Now bear in mind, this is "mostly before" the chineseoisasssssification of replacement parts, so that might bias the results

I can agree with that, but conversely, in my experience it's always been ECU's, and 1 pickup module. I guess the thing to do is use the K.I.S.S. rule.
