RE: Testing Starter relay switch
Command to start doesn't come through the ECM on Paccar. Smacking ECM won't help anything here. The best way if you can get it to act up is with a DMM while it's not cranking. You will have 12v from the CECU to the key switch going to a relay in the cab then that relay on the firewall then to the starter.
