This morning I went to start my truck and it just cranks, but no start. I hadn't driven it for a couple days and has been running fine for the four years I've owned it. Fuel pressure is 50-60. I changed fuel filter anyways. Engine[v6] will start only by squirting fuel into throttle body and will continue to run as long I as I keep feeding fuel. I connected a scanner to retrieve codes and scanner does not boot up. I tried the scanner in another vehicle and the scanner works fine. Any help or ideas will be greatly appreciated.

 

If the scanner needs power from the DLC, check to make sure the Cigar fuse isn't blown.
