Won't start

Ok so the title isn't completely true. It starts. But when it's cold it takes a couple tries. When I say cold I mean Cali cold. Like low 40s. BUT when I have her facing downhill she will start up every time on the first try. What could be causing this?

Anymore info?
Year?
Miles?
Recent work?
A way to monitor data live? ICP and IPR when cranking would be nice to know

Early build, most likely your HPOP is going south towards the border.

2003 (12/02 build) 125k new tranny 4" exhaust new injectors studded bulletproof egr cooler and oil cooler.
Why would gravity effect the HPOP?

That's right you had ICP issues last week?
Welcome to the club of the early build weak a$$ HPOP's.
It likely starts easier facing downhill because your not draining the pump and losing your seal/prime.
Only way to know for sure is an air test, but my money is on the pump.
Recently studded?

Yourself? $1000 or under with stock pump. A shop will charge mucho dineros with labor and mark up thrown in.
Go with a good pump, Adrenaline would be my choice(with I had looking back), but they are over a grand for sure last time I checked EDIT...........still at a grand. I think the OEM is around $700.

It's not that bad a job, but will take some time for the DIYer

Well, it's either that or you end up with an STC fitting, dummy plugs or standpipes, or all three on the later builds

When it's been started at least once that day it starts no problem no matter the temperature.
