    I didn't see the original posting, but if the car had a hesitant start at the beginning, and you changed out the cam sensor along with the crank sensor, then the ignition might be a related problem. Have you replaced or had a new key made, or does the key hang up in the ignition? My mechanic has changed both sensors, and the code is removed. Ten to fifteen good starts later the check engine light comes back on after the key was sticking in the ignition. Apparently this has been a problem for many across the web for this year and make car. Hope you find out what's wrong. If I find out the problem with my 98 Cav. I'll post again.

If you connect a scan tool and go into the data stream and crank the engine over does the scan show any rpms? Also have seen many times where the pcm connectors are corroded or wires are frayed. The pcm is definitely not in an ideal location for these vehicles. Let me know if the rpm's are registering on the scan tool or not.

Does not have any fire. what is wrong

Possible Ignition coil , Ignition control module ,( PCM ) engine computer. Your best bet is to take to a qualified auto technician and not replace a lot of parts you don't need ! I have repaired automobiles for the past 30 yrs. I have seen people thinking that they could fix it them self's and spend thousands before it was all said an done ! These new cars are very sophisticated , have up to ten or more modules that talk back and fourth shearing information on a serial data bus. I have a scan tool that cost $6,000 dollars that can access codes in all the modules. I have seen modules you wouldn't think cause a problem like no spark but it can happen. You vehicle also has an anti-theft system that could cause a no spark condition. So do you self a favor and take it to someone who knows you vehicle better then ever will.

Timing belt failure OR idle air control valve?

As far as the timing belt,if it has been on the car 7 years
or 75,000 miles, you just install a new water pump,belt &
all the pulleys & tensioners in one kit,after you check cylinder
integrity,valves,compression & such
A cylinder contribution test is done first with an oscilloscope
& software to do that.
Once the above mechanical condition of the motor is
out of the issue, you move on to other tests
Smoke testing for vacuum leaks,fuel & spark issues,etc.
Can you check timing belt-- if fairly new,yes
You can put a camera wand behind any dust cover
& you can use your scope software again to look at cam,
crank,injector & spark events in relation to when they should
Now the problem ! To find a shop that has that knowledge,
equipment and skill level,not many do.
All your mentioned parts can & should also be component
tested, in the proper sequence, if necessary
What can you do
You can try & get access to check the timing belt
Using a timing light,no,scan tool to look at data yes
You can test some,a few items, maybe,yourself if
you Google & study up some on how to do it
You Tube Video is a place you should spend some
time on any subject

Pathfinder "cuts out" at 2,300 rpm

Replace your MAF, its a little pricey around $280.00 or so but this will clear the code but make sure you have the ECM reprogrammed to perform a "learning" sequence since sometimes the code will not clear even though the vehicle will run like new. This reprogramming will most likely have to be a dealer performed procedure.

I have 60K miles. When is recommended transmission fluid change?

It should be done between 30,000 to 60,000 miles. 30,000 miles if you do lots of stop and go traffic like in rush hour and up to 60,000 miles if your out on the highway most of the time. (less gear change) As long as you service your transmission on a regular schedule, it should last you the life of the car. $100.00 service every 3 years is a good investment since a transmission replacement is around $2,300. Hope this helps and good luck.

My 1997 sunfire will not start when it rain, gets damp out or get cold...was told i need 2 new coils, 4 spark plugs, ignition wire and a valve changed...also told i have a gas leak and need a new gas...

Gas leak & tank would be my top priority. Try some ignition spray from autoparts store to get you by for now, as far as wires etc go, but get that fuel leak problem fixed first.

As far as the engine light goes, you can try going to an autozone who will scan it for free. Make sure you write down the codes and definitions. If you get misfire codes, replace the plugs. The rear plugs can be reached just by reaching around and under the intake. If its something else, repost. Once the repair is made, have autozone clear the codes again. The squeek is called the camshaft synchronizer, which is very easy to replace, but if done wrong, the vehicle won't run correctly. The part with a new cam sensor should be about 125 at a dealer, 40 dollars online.

The crankshaft sensor determines when to fire the plugs; if it has failed, no plugs will fire.
If you have no mechanic friends who know how to test this sensor, you should probably invest in an aftermarket service manual. They have simple tests for most sensors and conditions that don't require costly equipment or detailed knowledge.
I prefer Haynes and they are available on line here:
Haynes Sonata Manual
You may also find them elsewhere for a few dollars less.
