Hummer H3 Problem Solved | Thank you for the help!

Hummer H3 problem - intermittent crank no-start on first crank but immediate start on second crank. Model: 2006 Hummer H3 w/2008 to 2007 converted 3.7L engine.
Cause - 2006 3.5L intake cam sensor was incorrectly placed on the 2008 3.7L swapped engine resulting in improper computer timing.
Solution - relocate intake cam position sensor hole & set proper "air gap."
Thank you so much to everyone who has provided ideas and input with troubleshooting this issue! I hope my findings can be of use to others in a similar scenario. Leave questions and comments below! :)
