Drove it to work now won't start, doesn't even try to turn over. Has ignition power, but NO power to OBD2 port and fuel pump NOT coming on. Mini Fuses under hood all good. (Not blown). What could it be?

Sounds like a battery problem is the 1st thing to rule out. Have you tried jumping with another vehicle that has a KGB? ( known good battery)

I'm sorry. I've read some posts here that seem to indicate the FOB / key can cause start problems.

For me, it ended up being intermittent issues with the transponder in the key. Brought my second key in case and it started right up. Started using my second key and no problems.

Yellow with black wire corroded. If You get a P1633 KAM code. This is Your issue which will eventually lead to a NO START.
Fixed now.

Glad you found the problem...it's just astonishing how these issues unfold. You were able to drive it to work and at THAT exact moment is when it decided to go kaput when it is likely that wire had been like that for at least several months...
I know! Insane. I've had the p1633 code come and go. So I knew it had to be something to do with that. There's a great YouTube video of the same symptoms I had so I went ahead and went for that wire or those wires. There are 2 yellow with black that comes from the fuse box that are combined at that point to go to PCM. I clipped them both about 2 inches of wire and added fresh wire. Problem solved.

Well the open wheel well driver side is what I think causes the moisture to get up there into the harness. The wheel will throw water or in My case snow and dirt and soaks the wires in the loom and it doesn't dry out too well. Closing off the rest of the wheel well would be ideal.
