I have a similar problem. Brand new battery, and alternator output is good. Sounds weak and takes a little bit of cranking to start. Subbing to see what is posted.
From the bit of searching I've done, a low compression motor (90 or less psi) could cause this (probably not your problem since your motor is new).

Could also be the fuel system depressurizing while the car sits. To rule that out, jumper the F/P and GRND pins in the diagnostic box to run the fuel pump - run it for 5-10 seconds, then see if it starts up normally or takes a while.
If it is depressurzing, it's either a fuel leak or something with the fuel pump and assembly.

My baby was doing the same thing. Taking longer and longer to turn over until finally she didn't even start and would just crank away. When my bud was over helping me diagnose (fuel/spark etc) he noticed the microtech dash display wasn't picking up any rpms while cranking. Uninstalled the crank angle sensors, cleaned them and the harness plugs, tested their resistance (perfectly within spec) and reinstalled. She starts every time now. I think it was just 20 years of crap that built up. Not the original engine but I know the sensors were reused.
