I've had my 6.0L powerstroke in the shop 4 times in the last 3 months for the same issue, cranking but not starting. I replaced the ICP connector(not the sensor). Problem continued, dealership replace the Cam position sensor, this worked for about a month, problem cam back. Dealership said I needed a new FICM so I have them replace it. A week later the probelm came back and they now say I need to replace the entire wire loom, $1,040 for parts and labor, this is outrageous! I think they are throwing parts at it now and don't really know what the problem is. Any other ideas on what this problem might be?
