I have been dealing with this for 3 weeks have had a lot of good info on things to try IE:crank sensor ( i replaced wih new bosch did not fix)::::repair relay control module (had it fixed still did not fix)---i work at a salvage yard in texas used several scan tools no codes -took the a shop this week he is pulling his hair out-------saw a tread about egnition key and module could that be the problem-?-----------started out would die on let it sit a little would start back up,, a week later died would not start put on a used crank sensor forma 60k used engine we have here started right up drove for about a week died bought new bossch sensor would not start -it turns over but its like its not getting fire ---could it be the key and ring and module ?????? thx to all for help

 

Outside possibilities :
1. Camshaft position sensor.
2. SKREEM module ( as in thread about ignition key and module )
3. Fuel pressure ( there is a port on the fuel rail front passenger side of the engine, when it won't crank, just remove the cap and press the valve with a match or something and see if you get a face full of fuel )

Basically, if an engine turns over with the starter and won't fire, then it's usually one of these problems :
1. spark
2. fuel
3. timing
4. compression

 

Just a thought, if you have a second key, try it. One member had a key simply bite the dust, and the motor would crank and crank and crank, but never once fired. The security module was interrupting the signal because the key, although it fit, was not recognized.

 

my mechanic put a new battery in key fob it will not work to lock or unlock doors or panic buttom could that be it ?

 

No. The battery / lock / unlock / panic functions have nothing to do with starting.
There is a little chip in the fob that is not powered by the battery, but is activated and queried by the SKREEM through the little circular antenna around the ignition key.

 

I'm very interested to see the outcome of this thread. OP, very sorry to hear about your situation and wish you the best of luck with the solution. Starting problems in this car are one of my owner nightmares, since I'm a fan of long road trips.

 

It may be one in a million.. but what are the chances of the new bosch CPS being defective? Work at a salvage.. chances of pulling another from a car just for sh*ts and giggles?

 

After seven posts in another thread you decide to ask the same questions again in a new thread, why would anyone bother to post their replies again?

 

I too wonder about the fuel pressure, the service manual says it should be something over 45 psi.


But one thing, I had a weird problem with my Durango once, and it has happened to some Crossfires, too. Bad battery!
Does your car TRY to start, but can't seem to keep running? If so, read on:

This is what it would do:

1) Turn key, engine spins and starts.
2) Release key - engine dies right away.
3) I think, "What the hell?"

Try 1 and 2 over and over - no good. I think, "What the HELL?"

Call the hook, guy tows it to our favorite garage. Mechanics spend 1 1/2 hours, can't make it run. I pull up in my van, some old guy says, "trade batteries between his van and Durango". They do. Now, the van AND the Durango start.

Switch batteries back. Now the van still runs, but the Durango won't start.

Put Durango battery on draw tester - checks good!

They give up: They replace the two year old Durango battery - engine starts and I drive away.

There is SOMETHING about all the electronics in cars today. Even so, maybe before you change the battery, (if you go this route) you should clean and tighten the battery terminals and inspect the battery ground cable connection at the opposite end from the battery.

I know it sounds nuts, Just saying....

 

when i became a sr member i will know how to use this page i tried to go back and find where i last made a post but couldnt find it. This is not the most user friendly site,, the people are awesome such as your self - sorry to waste your time sir

 

If you click on your name.. a drop down box opens.. "find all post by"...

Couldn't find it in the forum handbook.. but it works..

 

DAMN! I've been here for 3 1/2 years and NEVER thought of searching my OWN posts like that!

 

I use that quite a bit when I know I've seen a post from one of you gurus and need to find it again, but today it isn't working (for me anyway). I just get a screen that tells me Sorry - no matches. Please try some different terms, or something goofy like that.

Must be like a half price free shipping sale at Amazon.. too many people logged on doing it..

But it does "normally" work.. LOL

 

It's not so much a waste of time but you get two threads answered by different people and the tale gets split into two.

 

What he said.. Found myself dancing between 2 or 3 threads at on point trying to help a new member.. "it does this" in one thread.. "it does that" in another.. etc.

Decided it wasn't worth my time trying to track it all down and resolved to my re-run of 2 1/2 men..

 

Now it is a month , no xfire -----mechanic is pulling it out of his bay says cant figure it out -called local dodge dealer, they will not touch it , service manager said if you bring here it will sit a while we do not have a mechanic to look at it, have replaced crank sensor bought two new bosch,,( didnt fix it) ,cam sensor (didnt fix it) relay control module repaired (didnt fix i)t ,new battery ,,new key fob and key (didnt fix it) . Skreem module (didnt fix it) ------still will not start ---turns over has injector pulse and fuel pressure no spark from coils out was told was in anti theft mode --skreem module --would fix any one wanna buy 2004 crossfire 71 k -anyone is texas in austin area that is a xfire guru---------------------plz help

 

Have you had the codes read, no mention of that so far in the thread. Cheaper to buy a code reader than keep buying parts that do not fix the car.

 

you are correct has used 2 different scan tools -- no codes given---when it scaned with engine spinnin over shows crank sensor working shows rpms --but no codes thx sir

 

My scan tool works with ignition on and car not running.
