I had this exact issue last season. Spoke to tuner and he said crank air/fuel needs adjustment. Never took it back and oddly enough it hasn't done it at all this season and temps have been hotter. I'm not complaining.

Mine did it again on Saturday, It cranked for about 20 seconds then started, The only thing that makes sense is Meth in the intake tube. If this is the case would it require a new Meth Pump?

Mine actually did it yesterday for the first time this season. I don't think it's meth related, at least not in my case since I don't have it. It's in the tune.

Frustrating? If only there was an easy solution posted 20 times.

You're being made fun of because your question has been answered several times but you're still asking waiting to get an answer that you want.
You're being what they call an ASKhole. You ask questions then argue with the folks giving the advice or ignore the advice given.
p.s. You don't have a carb genius...it's an EFI car.

Okay, assume the cranking airflow has been adjusted all over the board and still can't get it to hot start, what do you do then? It's getting spark and fuel, fuel pressure is good, injectors aren't bleeding off, and it has roughly 11 degrees of timing during startup. I've had this issue since it came from a reputable shop who tuned it.
Once running, the car runs great.

There's a cranking VE table and a cranking fuel table that I'd play with next. I've never really messed with them very much, but that'd be my best guess.
I'd just try a fairly large change both ways, say 25%, and see if it changes anything
If you have a wideband in the car I'd try to get it warmed up/working prior to starting the car and try to see if it's lean or rich right after startup. Not sure how accurate the sensor will be at that point but it's worth a shot.

The timing in the hotter tables goes from 7 degrees all the way to -10. The 200 degree area where this does it is where I'm having troubles. I bumped it a few degrees and added a little more airflow to it. It seemed to help but being so random it's hard to say and we've played this "great, it starts and it's fixed" game before only to have the better half asking if we need to trade it in on a C7. The laptop might just need to live in the car for awhile. These issues were why I was asking to see your tune.
