Question about Nissan Altima
My Nissan Altima usually only starts on the second try. If I hold the key in the ignition and let the fuel pressure build up before starting it, it starts almost immediately. I have heard that it might be the Camshaft position sensor and I replaced that, but it didn't help. I also heard that it might be the fuel pump pressure check valve. I can't find any help on that valve online. Any help would be greatly appreciated. Also while driving, the car lurches forward when switching from 1st to 2nd gear. I know it has to be something with the fuel but I'm not sure what it is.
I would put a canister of fuel injector cleaner in your vehicle to start out with. Only cost you about $7 bucks. This should help if you have some fuel line gunk causing the stall. I would not think it is a spark plug or sensor issue because you are able to start it when the fuel line is pressurized. This leads me to believe that it is a fuel pump issue. I know the Altimas have a sensor to detect that enough pressure is being exerted, but it doesn't mean that it can get to that pressure immediately. If this is the case you will have to change the entire fuel pump assembly. I suggest you get use to putting on your seatbelt after you turn your key halfway to let the pressure build. I have a Nissan Sentra and it had the same issue, I replaced the fuel assembly...it went bad again after 2 years.

Have you done a tune up like replace the fuel filter, change oil and replace the spark plugs.

i would try a fuel filter first. the fuel gauge going crazy is most likely the sender they go bad and eventually stop working. the bummer is you have to replace the fuel module. these aftermarket are about 200 bucks. the module comes with the pump and sender which is the next part you want to look at. gm has some issues with the harness to the fuel pump externaly. it actualy will melt and start to lose conection. i would check this by visualy inspecting the plug on top of the tank. unplug it and take a look. if it is at all disscolored replace the pump (module). the new pump comes with a replacement harness (make sure its in the box)hope this helps and good luck

BEFORE YOU TRY TO START YOUR CAR, TURN THE KEY TO THE ON POSITION AND STOP TO HEAR A WHISSING SOUND COMING FROM YOUR FUEL TANK. IF YOU HEAR THAT NOISE, THAT IS YOUR FUEL PUMP ENGAGING AND IT IS WORKING FINE. IF NOT, YOU SHOULD DEFINITELY GET IT CHANGED. ITS A GRUELING PROCESS SO HAVE A MECHANIC DO IT. IF YOUR FUEL PUMP IS WORKING, TRYING CHECKING THE PRESSURE OF YOUR FUEL. YOU MIGHT NEED A NEW FUEL FILTER(IT CAN GET CLOGGED UP) OR YOUR FUEL PRESSURE REGULATOR MAY BE MALFUNCTIONING.

You are incorrect sir. There is a very good Youtube video showing you exactly where it is that is how I changed mine. The Crankshaft is located behind the engine block below and around from the cam sensor which is easly spotted looking at the engine. The crankshaft is in a difficult spot but once you figure out where it is it's easy...ish hope this helps
