Recently change the starter 2 weeks ago because the old on die out at first it was working really well 1 crank the car started up but now all of a sudden i have to crank a few time before i can start up the car got the starter from Nissan Dealer the Starter is less then 1 month old now i am having trouble starting up the car i try with another Starter still have the same problem i replaced the Crank Sensor and Spark plugs are new any idea why i am having this problem can anyone help me out THANKS

 

If it's cranking ok, but not starting, it's not the starter thats causing your hard start.

 

YOU MIGHT WANT TO JUST GET THE CAR CHECKED OUT A THE DEALER ....THEN FIX THE PROBLEM YOURSELF....ITS NOT THE STARTER.....

 

Here's what you do, if you already haven't tried this. Get in your car, turn the key to ACC so all those lights turn on. Wait for the 5 beeps to stop beeping and crank on the car. What that does is it warms up your fuel line. I live in Chicago and the past few nights and mornings the temps have been in the 0-15F range, and so far no problem starting. The copper plugs I'm putting in this saturday shouldn't hurt either...

 

Easy on the caps.

the starters only job is to turn the engine....if the engine is spinning that's not it. if its spinning slowly, your battery might be getting old, and the cold weather brings out the bad ones....local auto parts/battery stores will test them for free. it is normal for it to take a little extra to start a car in the winter....but if the engine is cranking and cranking and just not coming to life, you need to look deeper....plugs are a good first step.

After cleaning the throttle bodie on mine, the cold starting improved, but something else is a-miss in my car. I have new plugs coming next week, but the current NGK plats only have 45K, just put in a new fuel filter and starter as well (mine wouldn't engage anymore and I was too lazy to regrease it). If new plugs don't help...well, i'll worry about it later....it can be a lot of things, you just have to work through them one by one....

 

here is some info I dug up:

When you switch off your engine, the fuel injection system is supposed to maintain its pressure. This is called "residual pressure" and it helps the engine start easily at the next start-up. If your engine has lost the residual pressure, the engine will not start with the usual ease.

How could the engine lose residual pressure?

#1) The fuel pump check valve leaks. The fuel returns to the fuel tank. The engine is not flooded.

#2) The engine has one or more fuel injectors which don't close properly. The fuel leaks into the intake manifold, and sits there until the next start-up. The engine is flooded.

You may do some simple tests to determine if your engine is hard to start because it has lost residual pressure.

Test #1, for leaky check valve.
Turn the ignition switch to ON, wait ten or fifteen seconds, and then twist the key to START. This brief delay gives the fuel pump time to build up the normal fuel pressure. If your engine starts and runs readily after this brief delay, you may have a leaky check valve.

Test #2, for leaky injectors.
Press the gas pedal to the floor and hold it there while you crank. Wide Open Throttle while cranking is a signal to the Engine Control Module (the computer) to clear a flooded engine. If your engine starts and runs readily with the "pedal to the metal" you may have leaky injectors.


Remedy for #1, leaky check valve.
I suggest you just "learn to live with it" and make the ten-second delay part of your normal routine. The check valve is part of the fuel pump, situated inside the gas tank. This is an expensive repair.

Remedy for #2, leaky injectors.
Buy three cans of name-brand fuel injector cleaner. Follow instructions on the can, and treat three successive tankfuls of gasoline. I've had good results with this kind of "snake oil". The three cans cost only US$5, so it is an inexpensive gamble. If the cleaner fails you may have to replace the leaky injectors.

Good luck!

 

in my case i also have a rough idle, so I have a concern its a leaky injector...given that the fuel line had no pressure in it when i replaced the fuel filter...but my fuel mileage is pretty good...in mixed driveing around 24-26. i would expect a bad injector to hinder MPG. I am going to try an intake manifold cleaner and a fuel system cleaner before i panic about injectors.
