At the cooling fan relay two terminals should have voltage....then if you jump terminal 30 to 87 this shoudl cause fans to come on....If so check to see if dark green wire between relay and pcm is broken....If not replace pcm. Fan should come on with coolant temp sensor disconencted.
Then disconnect pcm and pcm and ground dark green wire from relay to see if it comes on....If so thsi verifies wiring is good and ecm/pcm will need to be replaced.
