After removing bulkead connectors to clean no start

Start by making some tests. First, suspect that you may have pushed one of the terminals out of the connector. It's possible your problem has nothing to do with the bulkhead connector, or that you wiggled/ shook loose a connection nearby.

So what is it that gives the coil starting voltage?

What is it that gives the coil/ ignition RUNNING voltage?

Go to MyMopar.com. Download a service manual. While you are there download the simplified aftermarket diagram for your car, it's sometimes easier to follow, but often not as detailed

There are TWO sources for ignition voltage, IGN1 and IGN2 come from the ignition switch. IGN1, traditionally "dark blue" is ONLY hot in "run."

The IGN2, traditionally brown, is ONLY hot in "start." Stick a meter or even test lamp on your coil+ You should have "same as battery" during cranking, and at least 10.5V

Well I checked the bulkhead connectors once again and checked voltages at ballast and connector to ECU with key in on position and they were lower than the .5 volts lower than charged battery. Since I had replaced the ECU not long ago with a blue high rev one I decided to re install the blue box I had on hand. Tightened it down and connected it and pumped the gas twice and she fired right up, I put the newer blue box in and she would not fire up. SO what ECU is the best to use. I've heard orange are no good these days and since the new blue high rev did not last long at all should I go with a chrome one. I've heard they are good.
