Starting Issue (Getting Worse)

Starting Issue (Getting Worse)
Hey all, I'm having a starting issue on my 2001 maxima SE. 150k miles, 5 speed manual transmission.
Ever since I bought the car it would have a occasional, like once every two weeks or so, problem starting. It would like hesitate to start. it would crank for about 5 seconds and then start. Ever since then it has slowly been getting worse. And since the past week its gone very bad. It does it atleast 2 times a day. Now while it's cranking it would like die out, make a loud clunking noise and start up. I have taken a couple videos and uploaded to youtube. I put the link in the post as it did not let me upload it.
What do you guys think it might be? The starter? Flywheel? Fuel Pump?

There are a number of threads on this topic. Start with the obvious...battery, starter, fuel filter (yes there is an actual filter even though manual says otherwise), MAF (may be going out), throttle body (dirty), CPS.
Do a search and you shall find...
I'm assuming it runs fine once it is started.

The MAF is new. I changed it about 6 months ago. It was a brand new one with the green dot on top. The throttle I haven't cleaned cause some people tell me it's not good to do so because of a coat the throttle has on it that might be wiped off when you clean it. Which will then give you problems. When I changed the clutch last september the mechanic said the started looked like it was on it's way out. But never given any problems. Unless this is it. As for the fuel pump, I'm not sure in what condition its in.
Could it be that a couple teeth on the starter might have broken off?
And yes, it runs fine after it starts. That I know of at least.

Starter teeth would be a freewheeling whirring noise and then suddenly slamming into place... I don't think that's it.
Check the Fuel Pressure Regulator and Fuel Dampener. What you're describing is exactly what I wrestled with for almost a year, and it got progressively worse and worse. Basically the engine is flooding itself out as it tries to start.

What about the crank shaft position or cam position sensors? From what I understand my 2001 should have two crank and one cam sensor right? Would those be giving me this problem?

Your starter is about to go out I'm pretty sure, mine did that just a couple weeks ago and I was forced to leave my car in a parking lot overnight, luckily it was in town though. But yeah, my symptoms were that it hesitated to start about 2 or 3 different times but on and off. For two weeks, then it just died, but the thing is I had just started the car maybe 5 minutes before the time it died so it is pretty unpredictable

I'm going to try and check the fuel regulator and damper since I've been doing some reading and it may be the problem.
To my understanding, if you remove the vacuum line on the damper and regulator and there is fuel coming out of the end of it. They're shot right?
UPDATE: Fuel pressure regulator and dampener seem to be fine. I did the test where you turn the car on and let it run with both vacuum hoses disconnected. No fuel leaking on either.

Okay guys, so my car completely died today. It did not want to start at all. I have a manual tranny so I was able to push start it. I pulled codes P0420 (cat. conv.) P0335 TWO TIMES (Crankshaft sensor) and P0464 (weird fuel sensor code)
Any Ideas guys?

The cleaner has to specify it is for fuel injected engines, not a universal spray.
#12
I'd check the basics as someone already suggested- battery voltage, battery posts, spark plugs, grounding. To test ground you can temporarily put a wire from the negative battery post to the body just to see if it changes anything.

asking cause i have been wanting to change or clean mine and too lazy to take my fuel pump out
#15
Yes, that's the one he's talking about. I'm planning on buying oem fuel filter and changing it. There's a write up on here on how to change it.
#16
Oh, and I installed the new starter, I also cleaned both crankshaft sensors. The REF sensor by the pulley is rusted. I just cleaned it as best I could since it hasn't given me codes for that. The other sensor POS by the tranny was really nasty and covered in oil and metal shavings. I also went ahead and cleaned the throttle body since I had to take the intake out. Turned on just fine. I'll keep you guys posted on what happens. Thanks for everyone's input on helping out.

UPDATE:
About a week after install of new starter. The long cranks begin. I'm leaning toward the battery. Cranks a while, then kind of dies out and then roughly starts again. No SES codes at all. New starter, Cleaned both crank sensors.

Disagree on battery. If it's cranking hard enough to eventually start it, then it's not going to help make it start faster. (bad explanation but maybe you're picking up what I'm putting down.)
Did you check those vacuum lines for the pressure sensor and damper? They are readily accesible while you have the starter, battery, and air box out.

Also, something i forgot to mention. When I took off the POS Crankshaft sensor that is by the oil pan. I did notice that the little magnetic tip which reads the crank pulley was super rusted. Like rusted to the point that I couldn't clean it at all. I got the grime off, but it's rusted.
Maybe that can be the culprit?

Alright so the problems are starting again. And they're getting worse. Feels like my car will leave me stranded sometimes. Took the battery to auto zone to have it tested. It's in perfect condition. Brand new crank sensors and cam sensors. Starter is about 4 weeks old. I'm starting to think it might be a fuel related problem. Probably going to have it scanned for codes again tomorrow after work. Any other info would be greatly appreciated.
Thanks guys.
Thanks guys.

I would check the flywheel. You can take off the starter then look inside the hole and see teeth. You can turn the crank on the passenger side of the motor to rotate the flywheel to see if any teeth are missing.
#23
When I changed my starter about a month ago the teeth looked fine. And it doesn't sound like it's missing teeth. I bought a grounding kit from a fellow member. Hopefully that'll make things better as it has done good to some members with a 5th gen.
#24
Okay guys. I might have finally beat this. It's been one week since I installed my grounding kit and I haven't had a single hard start since. Hopefully it won't come back. -fingers crossed-
#25
Replace cam sensors? But that would cause it to die and not stay running.
One of the crank sensors must be bad b/c cleaning them off will work if they're good.
Please keep update again, later. I find it interesting that a ground can do that.
