Ok. Looks like something is definitely not right. Next I will look at the crank circuit and see how that is supposed to work. Looking at the diagram, none of those wires crimped with the alternate wires seem to be associated with the crank circuit, so makes no sense! Did you try bridging the wires that go to the temp sensor? If not it's worth a try as it should tell the ECU to run the fan. If it does, then the sensor is not switching to a closed circuit to activate the fan relay. I need to check the diagram again, but left the printout in my office and can't print at home at the moment, so may not be till tomorrow now. I will get back to you as soon as I can.
