No start. New ficm power module. Ran for a week then felt like power was being lost. Ended up shutting down. Code p0113 for high stake intake air temperature sensor. Replaced. Still just cranks but wants to start.

Make sure your FICM connectors are seated correctly.

AIT sensor shouldn't cause a no-start...well, unless it has something to do with VRef voltage (not sure if that one uses it or not). For giggles, unplug your IAT sensor and see if it starts. What year 6.0? Did this just start happening out of the blue, or was there any recent work done to the truck (besides FICM)?

Otherwise, we need more info. Please provide the following values KOEO and while cranking.

It's a 2007 f350. The ficm power module I replaced then a week later this issue. While driving home just felt weird. Pushing the gas was fine but just cruising it was like back and forth.

Don't know if you figured this out but you need to check the injector harness going into the ficm, and the engine harness going into the ficm.
