Roll eyes as much as you like but new parts have the habit of fixing old problems, but the air pump loss would not stop the starter from working. Faulty solder joints in the RCM will stop the starter from operating. A new RCM should not have those bad joints therefore it should start. I was pointing out the fact that it was not the burnt contacts and that the problem lay elsewhere.
I hope the problem is solved and the problem does not arise again.
