E70 x35d no start after repairs

[GMuntz]

Hi Folks, I had stalling and low coolant temps so I narrowed down the issue to the crankshaft position sensor and the thermostat. I had codes for the CPS, nothing for coolant temperature.

After removing power, replacing parts over a few days, it's all back together and cranks but will not start. It's on a set of ramps and I got the DSC 4x4 warning and angle steering sensor. Cleared those (Foxwell NT540).

At this point, I've triple checked all my connections during the repairs. Checked fuel related fuses (although I didn't open the fuel system). I can't figure out why it won't start. No codes when scanning for BMW codes. I now have a low battery warning but the failure to start has been consistent from the beginning.

Any ideas on this one? Is there something I have to reset after having the negative battery cable removed for a few days?
