I have a 2003 maxima it won't start it was in my garage for 3years it wasnt turned on so far I changed camshaft sensor crankshaft sensor ,starter,fuel pump , spark plugs, and still it won't start it keeps just cranking but it won't turn on can someone help me please thank you

 

Have you tried jumping the battery?

 

I have a new battery and i tried jumping it too

 

Well I hate to state the obvious, but are you sure it has fuel? You claim you've changed the fuel pump so you must know how much gas is in the tank, if any.

 

That sound like you might need to get your key reprogrammed or replaced. If the car attempts to crank but never starts that is an indication the transponder is not working properly.

 

I do got fuel I add fuel after I was done changing the fuel pump but I did lost my key and I got a new one... So u think it mite be the key?

 

Maybe...

 

****, old gas or it gummed up somewhere? on a bike, without stabilizer the gas would gum up the lines or small carb passages making it hard or impossible to start (depending on the size of the bike and its carbs). does it crank?

 

If the car was sitting for 3 years, the gas is turning itself into varnish.

As others have said it might be the key, so I'd check that first. If that's the problem, drain that old gas out and put in fresh gas.

 

before you check the key i would do this;
pull the fuel pump fuse buy starting fluid and drench the living hell out of the throttle body,
jump in the car and try to start it if it sputters and spit and tries to start you have bad gas.
if its the same check the key. if im correct, im not too sure on this one, but i believe the key cuts fuel and ignition. so if its the key you would have no spark.

someone please correct me if im wrong

 

I remember reading that the immobilizer works by letting the car start and when the system realizes that the key isn't the correct one, the security light stays on and the car shuts off. I might be wrong tho.

 

when i bought my car, i tried to start the car with the valet key or whatever the previous owner gave me with no chip in it. it just wouldnt start, then fired right up with the proper key. but i later scanned the ecu and i pulled a security code. so if the key is the issue, a scanner should reveal a security code(i cant remember the exact code number tho)

 

Check for the 3 elements: fuel, air and spark!

 

Sounds like the key is the problem does the security light stay ? If so thats ur problem

 

Well, you should drain and replace the gas anyway, so I would start with that.
