Car wont start ...

Car wont start ...
I got a 01 Maxima and last week it decided not to start . I check all the sensors (crank , cam etc ) One thing i notice is when i take the plugs out they are soaked with fuel .It will crank but wont turn over the starter is new . If i wait couple days it would start up one time after that no more . It seems like there is too much fuel going to the motor . I even change the fuel pressure regulator . Did anyone had this problem or know whats going on . Thanks

Well I keep thinking of possible reasons, 1. the spark plugs are bad or perhaps need to be re-gaped (possible carbon build up) or simple replace them 2. Sticky fuel injector/or multiple sticky injector do to a build up of gum or carbon.
So you can inspect the plugs again, as you said they are a year old, you could also run Chevron Techron Fuel System Cleaner in your gas tank to see if it will help free up your injectors ... or even run a bottle of seafoam in your gas tank.

Mine did this last night actually. All i did was the ecu reset procedure and it fired right up! followed the reset procedure here: http://forums.maxima.org/5th-generat...tting-ecu.html
Cant hurt anything to try that. Its the procedure listed in the first post

You can gap both; plats are easy, iridiums are pretty brittle and will chip if you don't treat them nice. But both should be pre-gapped when you buy them.
Regarding the OP, if car is not starting it would be normal for 'extra' fuel to be in the combustion chamber. I think the issue is the ECU or a crank sensor. You said you checked the sensors; how can you tell if one is good or bad?

Your probably correct about not wanting to re-gap the plugs, I had only made that suggestion from what I had read on the OP, not being able to start the car and find heavy amounts of gas in the plug area. One of the suggestions in that article for the gas being there was that the plugs could be "old" and the other was they may not be gaped correctly. The other area raised in the article was possible plugged fuel injectors, as the reason for the lack of ignition. So hopefully the OP at least has a couple of option to at least investigate.

I actually change all my sensors to be on the safe side . And still no luck . and i also replace the plugs too . I'm lost . im gonna try reprogramming the ecu and see if thats goona help . And also no security light

similar problem other then the injectors spraying any fuel. your sounds moor like a spark issue mines seems moor like fuel issue. Either way same symptoms. me and my brother replaced the cps and both css sensors. still no luck. The check engine light isnt on either. We have no way of knowing if there is any codes in the ecu right now with out having it told somewhere. I posted this in the newby section. I hope you get yours figured out.
Im no mechanical but have a lil experience with cars. My brother has a 5.5 gen maxima. He started the car after sitting all day. Drove it about six blocks and it cut off on him. It hasnt started since except with starter fluid. We hear the pump. I took off the fuel pressure regulator to see if it was getting fuel at the rail, which it is. I know its getting spark because it will start with starter fluid. It has had the recall done on it. We replaced both css and the cps sensors. Still wont start. Next we will take off the maf sensor and clean it. Since it is getting fuel at the rail as will as it will start with starter fluid which is means its getting spark. The only thing I can think of is the ecu isnt allowing the injectors to spray for what ever reason(sensor ect.). any help would be greatly appreciated. Thanks and thanks for having this great forum.

And Unless your car has had the battery unplugged a lot for a long time, it can take up to 48 hours of having the battery disconnected to clear the ECU.
It's not a bad idea if you can spare a day or two.
Now, to address your OP, I have some questions:
1. Does the car bog/chug or try to start at ALL? Or does it JUST crank and nothing else happens?
(if it's ONLY cranking, it's not likely plugs or fuel delivery)
2. Have you tried adding a ground to the starter? http://forums.maxima.org/4th-generat...verything.html
A bad IAT can cause this symptom IIRC also. But I'm leaning toward poor starter ground.
