Random issue out of nowhere. Got a couple things from the store and when I came back out, the truck wouldn't start. Cranked strong, but injectors weren't firing.
Checked everything over and was about to swap in a fresh cps when I noticed my Hydra was on 00. Flipped it back to a setting with a tune and she lit right up.
1. is high idle
2. is daily driver
3. is the hot tune
00. ?? that would be stock as I understand it, but she just cranks, no start.
My pcm is still split shot. I was under the impression that it would start, just run like crap with single shot injectors. Until now I've never tried it.

What bothers me is how the hydra changed settings on its own. I'm starting my trek to sunny Montana Wednesday, now is not the time to be having issues. So a lil bit of panic.
I've picked over everything. Connections are all good. No shorts anywhere.
Ideas?
