I had the same problem, unhook the 42 pin connector under the turbo pipe and cycle the key and see what happens. I had the same problem and traced it that way. mine was the connector to the uvch on the driver side. just changed it and it fired up. Even cold starts now.

Please don't throw money at your truck. Take the time to test so you don't buy parts that wont fix the problem. It could be a bad wire at valve cover connection, where main harness crosses over valve cover, or in bundle from IDM.
