New battery tested good, but car not starting

Just wondering if anyone with similar issue and found a remedy to the issue.
I've searched and performed a few recommended tips below with no success.
Any suggestion is appreciated. Thanks

Basic trouble shooting performed today:

- Engine turned but would not start
- Battery is less than one year old and tested good (see pic)
- CCA is above recommended number at 854 cca
- Battery terminals are clean and tight
- Viper alarm disarmed (no engine start installed)
- Tried valet the key with no success.
- All cluster lights on bright but not dimmed
- Brake lights working
- Z4 would not start in P or N (even with all lights turn off)

Ok it finally started up, but it was choking and pushing out alot of smoke. I have to hold the gas pedal to keep it from shutting off. Seemed like the fuel was not making way to the fuel lines or something. Maybe the fuel pump is dying on my 2003 E85 Z4

What color was the smoke? Black? If so, that would indicate a rich condition, not clogged fuel lines or a bad fuel pump. Possible causes might be a bad MAF, TPS (throttle position sensor), or some other sensor.

Best bet would be to run a scan on the car for codes and see what that tells you about the problem.

could it be bad gas? Was the car sitting for a while and gunked up the lines?

Alot of white smoke came out upon startup that day,
and yes the car has been sitting for a few days in the cold garage
with temperatures in the mid to low 30s.

I've been driving the car daily this week with no issue upon starting.
