A couple of starting issues

[aeonflux]

Still struggling to get my '75 240D starting properly, and was checking to see if anyone has had similar problems. I have two issues that I am not sure are related:

1. The car begrudgingly started before I swapped out the fuel injectors. It started three times after the swap, and when it is running, it runs better than ever. Good idle, no smoke, better acceleration, no stalling. The problem is it won't start. When I crank it now, I don't hear fuel delivery.

2. Before I changed the injectors, it would start sometimes, but the battery would lose charge after 30 sec or so and after that would need to be jumped. It still does this after the injector change, which I new it would, but I can't even jump it now.
Batt tested good
Starter rebuilt
Alternator tested good
Battery at 13.05 volts off, drops to 12.10 volts while the glow plug light is on, and rises to 12.55 volts after relay clicks off. 12.10 and 12.55 too low to get starter moving.

This girl won't let me rest. Just one month of worry free driving, start small right?
Thanks again for any insights. This site has been a lifesaver.
