I am not sure what type of injection system I have but it definitely is
fuel injected. I too think (am hoping) it is technique related,
certainly the least expensive route to a solution. I am leery of
burning up another starter while trouble shooting technique. My
un-preheated cold weather/cold engine starting technique is very
similar to my warm weather/cold engine technique and is as follows:

throttle open 1/4 inch
mixture full rich
electric fuel pump/prime on
wait a few seconds (2 at the most)
crank

In warm weather it starts right away. Colder weather takes 4-5 seconds
of cranking before it starts. Cold weather takes major cranking and no
fuel pump after the first attempt. Sometimes I get it going and
sometimes I don't. Both engines are very difficult and uncertain,
although the right engine is much more cooperative than the left.


I believe you are WAY under-priming your engines, when they are
un-preheated. Next time, try:

Throttle, Wide Open
Mixture, Full Rich
Fuel Pump, Prime for 6-10 secs, then Off
Throttle to 1/4 inch
Crank

Be ready to turn the fuel pump back on, if the engine starts to die
after it starts, otherwise, just leave it off.

As a side note, the older Senecas, with the TCM fuel injection and a
Cold Start kit, were unstoppable in the winter. You couldn't *not*
start those engines, no matter how cold they got. I don't have any
experience with the RSA system mated to a Continental 360, but the above
technique works very well on any injected Lycoming I've tried.
