Won't start on incline and cold (Cold Start Injector bypass?)

Did you ever solve the issue?
I have a similar situation.

 

I actually did solve this problem. I did tons of research and timing off will cause low compression readings and hard starting. I put the 3 degree cams in a couple years ago and for some reason the truck stopped liking them. I thought I must have put them in slightly off. Two weeks ago I pulled it all apart and the cams were fine. I flipped them back to normal timing put it all back together and I haven’t had a single problem since. I’m sure this doesn’t help you but that was my issue was timing. Not sure why the truck didn’t like the 3 degree deal but she is happier now that’s for sure.
