I think this is a common problem. Here is a copy of something I posted twice for two different people who were having this issue. For both of them, it did also turn out to be the pin on the CAN network in a plug just above the parking brake...
I also experienced the Starting System Failure. When I turned the key to on, I noticed the glow plug indicator light was not on which I thought strange. All else appeared normal. I turned the key to crank the engine and absolutely nothing happened - not even a click. I shut it off, then tried again. Everything was the same, except this time when I released the key from the crank position, a series of messages rotated through the LCD display - "Low Oil Pressure", "High Engine Temp", "Advance Trak Service Needed", "Starting System Failure", then a picture of an open-end wrench. This series kept repeating. I tried over and over with the same results. Long story short. Had it towed to the dealer. They found a bunch or really strange codes were stored, and changed some parts. Truck ran fine and I got it back. Two days later, same issue again. After having it towed to my dealer and after tireless work, the shop manager found a 'private' network between the Advance Trak processor and the Passive Restraint Controller wiring harness had a resistance (measured with an ohm meter) of .3 ohms, but when he wiggled the connector just above the parking brake, it went up to 100 ohms. It seems that the only information sent over this is data from the yaw sensor, which the Advance Trak processor apparently shares with the Passive Restraint controller. They added two wires in parallel with the existing wires and have soldered the connectors to rule out the crimping. There now is no variability in the impedance of the network, as it stays at .3 ohms (even when wiggled). They put the truck back together, then test drove it and it ran fine. Following this, Ford engineering contacted the mechanic after he sent an update on what he found. They advised him that if you skip over the next pin in the connector, the next two pins are one of the primary high-speed networks (yes, the CAN). They advised him to also parallel those two wires and solder them. They say that connection could have caused my issue of Starting System Failure. I have had no further issues. Common problem with this particular harness? Just a thought.
