Hi there,
Reading about some of the crank no fires, Trying to Narrow it down here, Compression Combustion Spark.
It's really cranking but no combustion and start, one thing I noticed, is that when I have the key just turned on in the ignition, not even trying to start it, i'm getting a super loud buzzing coming from the Fusebox area it sounds like. Could it be possible that theres a Blown fuse for something that's keeping it from starting properly?? I think I saw theres a fuse for the fuel pump I believe, wondering if that might be a place to start?

One thing I noticed yesterday was that - it took about 3 or 4 cycles of trying to crank, and it finally did start and get combustion. But I let it try for maybe 10-14 cycles to try and get it heated up a little bit and see if anything.. no avail.
