Question about 2005 Nissan Sentra
I have a 2005 nissan sentra 1.8 Liter my problem is the car will not start cold ... I have started it before and once warm will start every time ... once it cools off ( like sitting over night ) it will not start ... the car is turning over and sometimes you have to really pump the gas pedal to get it to start ... I thought the issue was with a injector as ive read that a leaky injector can cause such a problem .. i replaced 1 injector that looked horrable very gunked up ... #1 injector acted like they didnt want to come out .. #4 injector looked clean and even had some gas on it that was clean as well ... usually i would lean to believe that its the coils but as ive found with coils they usally work until warm then theres a problem so i know that thats not the issue ... is it possable that the fuel filter could be the issue ?? is there any known issues with this particular car pretaining to cold starting and or fixes for this issue ??? the car has to be firing on all 4 cylenders due to the car running smoothly when it does start and everytime after till its cold .... what would you suggest that it could be ? is there any tests that i can do to find this problem ???
These vehicles had issues with fuel pressure bleeding down when they sit for a period of time (like overnight). Nissan has issued a Technical Service Bulletin (TSB) on this issue.
There is a check valve in the fuel pump assembly that holds fuel in the fuel line so that fuel is readily available to the engine. This valve fails and allows that fuel to slowly drain back to the tank. The reason you have to crank the engine for a long period of time is that the fuel has to be pumped from the tank all the way to the engine- may take 10 seconds or more.
Once you start the vehicle, fuel is available and since the drain back to the tank is slow, restarting after even a few hours will be much easier.
The repair involves replacing the fuel pump "module" assembly (it's a service kit that contains the check valve mentioned earlier). The fuel pump assembly is removed from the tank and disassembled and reassembled with several new parts. This is a dealer-only repair. Depending on your level of expertise, you may be able to perform the repair yourself, but will have to buy the parts from the dealer.

Just had my 2005 Sentra in for the 3rd time - took five days of diagnostics and some other work which needed to be done.
Last year they said it was the fuel pump. Then they said timing sensor. *This* time, after checking with Nissan company, they were advised to replace the timing chain. I am going to document results, and my dealership also wants to be advised. Will keep you informed here....at least the timing chain was still on warranty.

Sounds like either it has a bad valve, or worn rings. With the mileage, I would suspect it's just plain getting worn out, when the engine warms up it internal tolerances are better then cold.

First from the fuel tank in side the fuel tank there is filter remove the screws on the top where the fuel gauge fitted when you remove gauge you can see fillter that is one sometimes blocked.
Next if you check fuel filter it is ok, but nissan sunny has fuel filter inside the caburator where fitted fuel pipe from the fillter clean that filler.
ather thiing is check your connections any leak or loose.
