so im hoping i could get some advice on where to start on fixing my car. let me give you some background on whats been going on with the car. so my 2004 crossfire has been parked for sometime now. im currently going to school which means im always broke. thus i would like some suggestions on a starting point of what to replace or fix first so i dont spend alot of money.

my car was starting to shut off after the temperature would get to the center ( warmed up). it started with just shutting off at a street light, but if i kept driving the car would stay on. but then the car started shutting off on me when i would be driving on the highway. keep in mind that once the car shuts off it doesnt want to start anymore. it just sits there and cranks and cranks and cranks but never comes back on. it will turn on once the car has completely cooled down. well now the car is not starting at all it is just cranking and cranking, this has now progressed to not even getting a crank at all. (ive checked the battery and it is good.)

so this is where im left at. i have been told by some people that it might be the chip in my key, or maybe the computer. since you guys are all crossfire owners maybe someone on this forum has had a similar problem and would like to share their solution. i would greatly appreciate any help that anyone has to offer, and if you need more information im happy to answer your questions. thank you.

 

Crank Positioning Sensor.. Click the red title in my signature below.. (CPS)

 

thank you for your fast response! now is this something i could do at home or do i need a mechanic? also can i looked at the part on ebay and its $124 for the Chrysler part or $25 for the Mercedes part. could you use the Mercedes part? sorry im a noob when it comes to cars. i just saw a youtube video of where the sensor is located, its pretty easily accessible to change out, but is there any re-programming needed after installation?

 

BOSCH only (well okay.. Advanced Auto..lifetime warranty..bosch rides behind my seat).. "If" you have the time get one off Ebay for about $45 bucks.. Advanced Auto was emergency situation and has done well for about a year now.. but was $65. Plug and Play.. literally .. LOL. If you read the link in my sig. you'll learn everything you need to know on it.

 

thank you soo much! my car has been parked for quite some time, due to me being in school 24/7 and working like a dog. is this the only thing that could be causing the problem?

 

HA.. if I could "guarantee" you that. I'd be getting paid by he post.. LOL.

Your symptoms are the classic CPS problem.. Lets say 95% shot at this being the problem.

 

awesome i will be switching this out sometime tomorrow or sunday and i will come back here and post and let you know what happened! thanks for you time

 

I'm going to hold you to that "be back".. I am heading to Texas next month.. LOL.
(just warn me fist if your 6'5 and bench press 400 lbs..okay?)
To many threads just dead end.. doesn't make for a good time years later when someone is looking for information.

 

Sounds like he may have burned up the starter also if the battery is indeed good. Maybe he has a 6 speed and can be push strted after he replaces the sensor. I was also thinking fuel pump if the cps doesn't do the trick.

 

I was just basing my response on the heat and die issue, but you could very well be correct on additional issues.

OP... you should be able to hear the pump when you first turn on the key prior to crank position. Also you might try disconnecting the battery for about 15 minutes. This has a tendency to "reset" the computer system.

 

It will be defiantly be what Mrmiata suggested, I had the EXACT same symptoms as you last week and found it out to be "Crank Positioning Sensor" when I connected my OBD scanner. I have since bought the part (make sure Bosch) and the problem is solved Best of luck!

Btw I am very amateur when it comes to do anything on cars but its so easy to replace, I did it myself. Its just more "fiddly" than being difficult!

 

I suppose if you get a CEL light with the problem and the stored code indicates a CPS fault there is really no guessing involved. I don't think the OP mentioned a CEL or if he had done an OBDll scan. Hopefully you are correct and the fix will be both easy and inexpensive for him.

 

Yes true, the OP didn't mention whether he had a code come up on the OBD scan but I assuming he hasn't been able to do this as it wasn't mentioned. I still would say its very likely it is the "Crankshaft position sensor" thou, as I had the exact same problems as the OP and that's what was wrong with mine. This is also a very common thing to go wrong and matches what he has said, so it all just makes it very likely this is the issue.

Btw forgot to mention but OP mentioned asking about the Mercedes benz part, that is the one you need. The genuine chrysler one is actually a Mercedes part (as these cars are essentially a mercedes and use all there parts), I am looking at the "faulty one" that I removed from my car and on one side it says Mercedes-Benz and on the other side it says Bosch. Hope that helps!

 

Seems the CPS doesn't always throw a code.

 

I wonder why the Bosch would be better than any other brand. The CPS is only a coil at the end of an extrusion, possibly iron cored. I am thinking over time they may become polarized/magnetized and cause problems. Possibly heat causes the coil to short and stop being the inductor it was designes as. Unless Bosch is using better/more wire there should be no reason the cheapest part shouldn't perform as well as the most expensive. I suppose someone could cut apart and examine all the brands side by side if they had the time and extra cash.

 

^^ Now nominated as official CPS investigator ...

 

sorry i havent been responding...i was on a mini vacation. im back get out of work today at 12 and will be heading to get the part ASAP. going to insatll today unplug the battery, get it checked and charged. hopefully all goes well, WISH ME LUCK!

 

it worked!!!! you have no idea how long my car has been sitting. i went to two mechanics and neither could figure out what was wrong with it! i should have come to you guys first!!! everything seems to be working great!

quick question do you know where i could find a driver side tailight, bumper, and driver side bumper? preferably cheap. ive looked all over the place like junkyards, and ebay and no one seems to carry anything. thanks for your help!

 

Glad to hear your up and running!
Mrmopar here on the forum has been dealing in parts.. Look in the vender section. But I'm afraid "cheap" might be a problem.. seems nothing is really cheap on these cars.. LOL.

 

LOL...i was afraid of that.

okay car has a new problem now. the car is shutting off, after about reaching 3k rpms. it just shuts down. starts up fine. i have a feeling it may be that it is not getting enough air. any suggestions?
