Car will crank but no Start
So when i crank the car it fires, and did a log is goes up to 600 rpm but then stall out instantly.
Sometimes it starts, When the motor warms up, i starts right up always. Thats the weird part
Things i checked.
-Spark plugs
-timing
-loose wires
-fuel pump
-compression is good
- Cam angle sensor
The only thing i can think it might be that i havnt checked is Crank angle sensor

It may be just a cold start problem. I was having the same problem till I reflashed the car. I'll go check exactly what I changed to get my car to start. It use to take me 15min to start my car and starter fluid till I figured out how to fix it 
I'm on E85 so my car is a bit different than yours.
I had to go into main map fuel settings in the ECU and change my Injector Cranking Enrichment IPW.
-0* - 108.1ms
18* - 83.1ms
45* - 58.1ms
68* - 48.6ms
As your coolant temp increases your cranking ms should decrease gradually.
That seemed to fix my car. Not sure if it will help you out or not.

i'd maybe check the iac valve. had the same problem but it was consistent to a low idle when i started. it died to if i didn't gas it. just pull it out and check it. make sure that it is still in one piece. when i took off my old one, the whole top half was gone. all the plastic was pretty much gone. good luck.
