El motor te costaba arrancarlo porque tenías cerrado los tanques de combustible, que por cierto en la Comanche no se abren los dos, se opera con uno abierto y otro cerrado, y más adelante cambias. Además la mezcla debería estar rica, y por último no has usado el fuel primer, que con la buena meteo que hay, con dos o tres veces es suficiente.

P.D. Igual me equivoco pero viendo la meteo del campo en el que estás, el pitot heat no te hace falta para el arranque, en todo caso una vez alcanzado tu nivel de vuelo.
Taxi y Landing lights tampoco, consumen mucho con el motor apagado.
En teoría no pasa nada por arrancar con ambos tanques dando combustible, si es cierto que como indica MicMic en los vuelos con el Mustang es práctica de algunos pilotos gastar primero un tanque y luego el otro en lugar de ambos a la vez o ir alternando. Pero tampoco he visto en el Handbook que hablen de líneas de retorno de combustible, de hecho no he conseguido un handbook con la gráfica de las líneas de combustible.
También es cierto que los que tengo son, uno de 1958 y otro del 60 revisado en el 73.
1) Are there any balance or load limitation between:
* fuel quantity in the right vs the left main tanks
* fuel quantity in the right vs the left wing-tip tanks
* fuel quantity in the main tanks vs the wing-tip tanks
I am not aware of any limitations but in practice, it's at least recommended to burn your tip tanks first, then the mains. You also don't want to have a big load diff between left and right tanks to avoid having a heavy wing in flight. Some burn one tank at a time (and consider this the right way to manage fuel so you can verify fuel available) and others burn both left and right together. If my fuel was ever very low in the mains, however, I would resort to burning one tank at a time if not already, because if one goes dry it can prevent the other from feeding the engine if both (the dry and wet tank) are selected. Also, with the tip tanks, the fuel gauge roughly reads 2x how much fuel is available (F = 1/2, 1/2 = 1/4, 1/4 = 1/8, etc.). This is how it is in our Comanche 250 and since we modeled our airplane, it's like this in the sim. So, when a tip reads just below 1/4, I stop and then leave it as an emergency reserve.
2) When exectly to use the electrical fuel pump?
* Should I turn it off after the engine is running? maybe only after take-off? another stage?
As a general rule, I don't think "use the electric fuel pump on takeoff or landing" but rather "use the electric fuel pump whenever I am low and I can't glide to safety if my engine quits." I also think you are supposed to use the electric fuel pump when switching tanks.
3) In which order should I use the fuel? Should I use the the tip-tanks first?
Yes
4) Should I use the tip-tanks also during: startup, taxi, take-off, landing?
No
5) Should I use the fuel selector in flight on "both" or is it better to use only 1 tank each time?
I think I addressed this above. It's personal preference, but better practice is one at a time
Also, for whatever it's worth, when burning tips I burn like this:
15 min left, 30 min right, 30 min left, 30 min right, etc.
