My car in the last 2 weeks has needed alot of extra cranking. I just cleaned the TB this summer and also tuned it up. Sometimes it will like fire for a split second then just go back to cranking. This car sits for 4 months in a building with stabil in the gas every year and always fires up right away. LIke I said it's just come on in the last week or so.

 

Might be time for a new ECTS - are all the other maintenance items up to date (plugs, filters, etc.)?

Just wanted to clarify: The car sits parked for 4 months every year?

 

Most likely ECTS but also possible CPS

 

Yeah it sits for four months a year in a building in tampa. All filters and plugs up to date probably 15000 mi on everything. What is ECTS and CPS. Is that coolant temp sensor.

 

ECTS = engine coolant temp sensor
CPS = camshaft position sensor
CrPS = crankshaft position sensor (2 of those)

One or more of these 4 are the most likely culprits.

 

No cel any way I can narrow it down some.

 

Hold the key in on position for a few seconds before starting. That will start the fuel pump and build up fuel pressure, and makes it start easier.

 

The ECTS is cheap - 20 bucks or so. I would start with that. Is it worse on cold starts/hot starts/ after the car has been sitting, etc. give us more info.

 

Well it's not real cold here in tampa but it seems that no matter how long it sits overnight or just a few hours hot or cold it starts the same like crap.

 

I had the same problem last year and it took 3 months at the dealer to find out the ground between the EGN and trany was bad

hope this helps

 

have you tried caressing the max, and talking to it, if that doesnt help try giving it a nice slap on the rear bumper and say giddity up. Worse come to worse i think we all kno what to do when you are in the back and you see the rear bumper then look down further and see the tail pipe, you kno what you may have to do

Lots of good information there!

Nope just got a check engine light for a crankshaft position sensor. How do I figure out which 1 of the 2 is bad.

 

Thats the best thing that could have happened to you!

The code will tell you exactly which one is bad... what code did you get?

 

0407 pwnz j00 ...

 

That's his beer talkin'...

(actually, those are wise words of wisdom from a man with 0407 experience).

 

I hate that code ....

 

Yeah it was a 0407 where do I go from here.

 

Check the resistance of the sensor Check the wiring

 

Read the farkin stickys cripes ...

0407
Diagnostic Trouble Code 0407 indicates a malfunction was detected when...
A) 120 degree signal is not entered to ECM for the first few seconds during
engine cranking.
B) 120 degree signal is not entered to ECM during engine running.
C) 120 degree signal cycle excessively changes during engine running.

Possible causes...
- Harness or connectors
- Crankshaft Position Sensor (REF)
- Starter motor
- Starting system circuit

 

Well I just tried to start it again it was turning over for about 5 secs then it just died. All I get is a click in the start position. I guess I should replace the starter first. The REF sensor is the 1 that is bolted onto the oil pan right.

 

... that code will also wreak havoc with your starter.

 

Are you saying if my CPS went that it might not let my starter do anything. I just don't know where to start. Should I just replace the sensor or the starter or just do both. I just don't want to be a parts jockey.

 

I don't think the CPS code will prevent the starter from turning over the engine, however a bad starter might cause the CPS code to be thrown... so... to put it straight: replace the starter.

 

That's what I wanted to hear I guess you gotta start somewhere.

 

A dead CPS kills the hell outta the starter since upon every start it must work harder to turn it over ...

 

Are you guys buying oem starters or something I tried the autozone 1 and it's got like 11 teeth instead of 8 so I returned it because I don't even think it will work.

 

What the hell are you on about!

 

Yeah my Maxima has been giving me a hard start ever morning and I don't know why,at first I thought it was the battery but it wasn't and I am just a a total lost

 

The 11-tooth reduction gear is the updated design. Thats what you want!

 

Well alrighty then I will try that starter then it just looked like it would not work so I passed on it.

 

Well it starts better but it's still not right now my CPS code is gone and now I am getting an 0401 code. Im gonna drive it for a while and see what else pops up.

 

Well it starts better most of the time. Now I have 2 codes again for the last two days I have had 0401 intake air temp sensor and today after a hard start I see the CPS ref has come back. Can an air temp sens trigger anything else sensor wise. The car runs well otherwise. I just hate to keep throwin sensors at this and not fixin the problem.

 

So ... what sensors have you repalced?

 

I think thats part of my problem all the sensors I have tested check out within spec. The only 1 that I have not tested is the ECTS. I probably should just replace that anyway considering it's original with 192,000 mi and it was not starting to good on a hot start however when I changed my starter that kind of went away now it only acts up every once and awhile.

 

Where is located this ECTS?
