It sounds like your preheat system is not working properly on the cold startup. Haynes has a Diesel Engine Repair Manual, part #10330 that will help you correctly diagnose and repair.
Battery volts at 13 is good but a fully charged battery should be close to 14.2. It would be a good idea to get the alternator output checked and a load test done on the batteries.
Hope this helps.

P0100 OBD-II Trouble Code
Mass Air Flow (MAF) Circuit Malfunction
Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.
You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness.
A code P0100 may mean one or more of the following:
* The MAF may be disconnected, or a wiring connection may be bad.
* The MAF sensor may be faulty.
Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back.
Then start with the cheapest, easiest repair procedures:
* Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires.
* Unplug and reconnect the MAF wiring harness a few times to clear the contacts.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information).
* Replace the MAF sensor.
