No spark
Ecu is grounded you can see in the picture i scrubbed it down to bare metal and did the same on the back of the ecu. Used new shinny bolts. I am getting like 10.6 at the coil and coil wire. I don't understand what you and trailboss are telling me to do. So I run a lead from the ground to the the connector that runs into the ecu?
We are trying to get you to test the system without the dist. Hook the entire system up, ECU grounded. All connectors hooked up
Now "rig" a spark test gap such as a spark plug from the coil tower to ground, this is so you can see if you have spark.
Next disconnect the dist. two wire connector. Turn the key to "run" so system is powered. Now take ahold of the connector half which leads to the firewall harness and not the dist. The connector has a bare terminal. If you touch that bare terminal to ground, it should make one single spark at your test gap. This shows the system is OK except for the distributor
You need to run the voltage checks for three reasons
1..........to see if the system is getting power with key in 'run'
2...........to see if the coil is drawing current. If the ECU box has lost power or ground or is bad, the coil NEG will be at full battery voltage. This shows no current is being drawn. Checking voltage at coil POS and it should be no more than say, 10V, this also shows current is being drawn. This is normal and what you want
3...Checking coil POS voltage "in start" shows the system is getting power during cranking. There are two circuits involved from the ignition switch
