    did you enable the engine fan? if not turn it on manually and have your a/c turned off. I unhook the discharge line from the air compressor also. any of these will abort the test.

    15w-40 will be ok and shouldn't be a problem. Did you replace the two outside wire harnesses that go to the ecm? If you didn't maybe pull the two plugs that go to the ecm and see if there is any bent or pushed back prongs? I really don't know what else it would be. You checked the ground wire going to the engine? I was hoping when you replaced the two harnesses in the engine that was going to take care of it.
