Put the key in the RUN position , then jumped it from the relay , and it STARTED .

So what does this mean? It starts in RUN position now with the key, what does it matter that I started the car in the RUN position by jumping it at the relay?



It means the ECU or coil is not getting enough voltage while the key is in the crank position. Could be a bad ignition switch or poor connection at the bulkhead connector.

You need to check both the coil+ terminal and the voltage feed to the ECU during cranking to see what the drop is. That is how I found out our power wagon had a bad ignition switch as the ECU voltage would drop below 9 volts during cranking.
