UPDATE: the mechanic who installed the engine did not fully tighten the bolt on the ground wire! ( located on the wall behind the compressor ) All of these problems were because of a ground wire that was loose. It took a month for it to fully stop working as a result of the mechanic not tightening the ground wire. It only ran right for about 3 days and then it started having problems where it kept dying. so, the lesson learned from this is that if a mechanic installs something on your car and a month later it dies maybe they forgot to tighten a ground wire!

I made this video showing all I know about my problem with my 2010 Chevrolet Equinox hoping that a genius will help me find the solution or help me with a list of items/actions to troubleshoot. New used transmission, new used engine, new starter, freshly charged battery. Over $5k within a year went into this damn car which is not paid off.
