A pilot script can be very hard to write, because it's potentially a rather different kind of episode to those that follow. It can be difficult to get the tone, structure and flow -- and, vitally, the story -- right when you're also trying to introduce the audience to these characters and dynamics. It takes a lot of skill to write a really good pilot, I think.
There are no set rules, though. It depends on the kind of sitcom you're writing. Some reset with each episode, some tell a story across the six episodes. Are all the characters "in place" from the beginning or is episode one a setup episode that shows how X starts working with Y or moves in with Z? If it's already starting in place, then episode one should be the same as any other episode, so it would make no difference.
If you are writing a sitcom that has a specific starting point for episode one (character going off to university/moving into a new house/starting a new job etc), it's often recommended to write episode two first and send that out as your pilot, because then you don't need to worry about how you're moving your characters into position -- they're already there.
Ultimately, though, the important thing is that the script you send out makes sense and makes people laugh. According to the comedy people at the BBC, "funny will get you a long way."
I don't know if any of this rambling has helped, but good luck!
