No, it's just a fact of necessity from the plot that Jaylah had moved into the Franklin and was actively repairing it with the intention of eventually leaving the planet; that she was actually pretty close to getting it working, but Scotty, being more familiar with Starfleet technology, filled the gaps in her knowledge.
We are meant to INFER this without having to be spoonfed a heavy-handed "Here's a list of all the things Jaylah repaired and here's a list of everything she didn't." Because Jaylah had found the Franklin, had been living in it for years, had built defenses and camouflage systems around it, and was in the process of trying to get it flight worthy, are all relevant factors here. If we were meant to assume Jaylah hadn't actually done anything to get the process started, she wouldn't have been living in the ship, she would have simply known where the ship was and asked Scotty to fix it.
If it was capable of escape when it first arrived, Edison wouldn't have abandoned it. That, too, is a requirement of the plot: Edison couldn't leave the planet, so he made use of the local technology in order to survive. The theory that the NEBULA was what was keeping him there doesn't really fit, because the nebula would only be a factor once the ship was actually in orbit, which is exactly where Franklin would still have been a hundred years later.
So in the immediate aftermath of the crash, Franklin wasn't going anywhere. The years marched by, rock slides and weather and sediment half buried the ship, and then Jaylah found it and started repairing it. Years later (Five? Ten? Fifteen?) Scotty arrives and finds the repair effort well under way. Jaylah's already patched up the MAJOR damage, so it's just a matter of finishing the job.
No, it pretty much hangs on whether or not we should choose to interpret a major plot point of Star Trek Beyond in the exact opposite way it was MEANT to be interpreted, for no reason whatsoever.
