A friend of mine has a 2003 Sentra SE-R that occasionally won't start, or cranks for a long time before starting. The dealer replaced the starter which obviously didn't help anything, and generally gave my friend the run-around. It seems they are waiting until the car is out of its warranty period and they are no longer responsable.
Anyways, has anyone run into this problem, and or know of some sort of solution?

Next step would be to check if its getting spark or fuel.. test the spark plugs see if they are still "sparking", and make sure its getting fuel. Its a process of elimination... also have your battery and alternator checked as well, autozone and walmart do it for free.

There is a TSB on the fuel pump. That is causing your problem. Running a fuel system cleaner, changing spark plugs and running high quality gas will settle most of it, but the dealer will replace the pump.
My wifes 2001 sentra wouldnt start this morning. It stalled on her once yesterday but ran fine after that.
I opened up the air box and sprayed some quick start in it. It would sputter but nothing else which tells me it is not getting any fuel.
It is my local mechanic no, I'm thinking I need a new fuel pump.
That could be a lot of things. Your injectors could simply be clogged. Try running Techron which cleans intake valves and injectors safely. If your gas mileage is low, it is very possible it is the injectors. Also check the spark plugs. IMO the most lilkey problem is clogged injectors. If they are clogged too badley, you will need to have some certain things done.
it could severely restrict flow, and start ups are where it will show most. if this was happening, you would have low gas mileage. what brand gasoline do you mostly use and what cleaner did you use?
Gas mileage was fine - getting about 650km to a tank (405 miles)
I usually fill up at shell with 87 octane gas.
The cleaner I used was a Canadian Tire brand.
Apparently dealer discovered that the ECM was fine and that there was no power getting to it. There was a couple of corroded wires that powered the ECM - cost was $200 at the dealer.
My 02 Sentra SER is having that problem too, sometimes it'll turn on quickly, but sometimes it'll stuter, especially after running the car for 15+ mins, turning it off for 5 or so mins, then trying to turn it on again. I'm thinking of taking it into the dealership.

Could be the fuel pump...mine is starting to go but until it becomes very readily reproducable I'm not going to take it to the dealer. Even when it does, since I'm modded to high hell, I havent a clue if they will help me.
The long crank time is due to your Fule pressure regulator in your tank is bad. It is integrated into the fuel pump..So replace yor fuel pump and you will be all better. I have seen wuite a few that way.

Sapo
Is that where the actual problem of the fuel pump TSB stems from?
