I have a interesting problem, I have a 2007 is250 awd that has thrown a u0105 code. I have took off the ficm and seems to be no issues with the wires or module itself. Prior to this I had no issues, but I drove the car in decently deep snow 2 days ago and no it wont do anything. I have everything else electronically working, new battery and newer alternator. It did start for 20 seconds after a new battery and it turned itself off. Now when I hit the button I here the starter relay and nothing happens. Any input would be great

There's been a few cases of this around here. It's either a faulty module, or the fuel pressure sensor is dead. The sensor itself is a $30 part off eBay, part # 89458-30010

Indeed it does sound like the fuel pressure sensor. Behind the surge tank is the connector to the sensor...try disconnecting it and see if it starts (I should have done that before replacing mine because it turned out to be the fuel pump). At any rate, you may have to take a few things off to get to the connector but that will at least narrow it down.

Edited to add: here is the link that shows the location.
