Wareaglescott's Coyote build thread - INDEX ADDED TO POST #1

The box with the pcm was delivered in a tremendous rainstorm and was wet. I fear moisture has got into the pcm and is causing my issues.

Highly unlikely the PCM was damaged by a little moisture. Those things are made for the harsh environment under the hood. Including heat, cold, water, salt spray, etc. The internal circuit board is actually completely sealed with potting material during final assembly. One of the reasons they're basically not repairable. That plus all the miniature components surface mounted on the circuit board. Pretty certain they're all made similarly, but this one I have personal knowledge of. Spent lots of time at the plant in Texas with my former employer where these specific Ford modules are made.
