the other day my brother was walking to his 2004 ltd. crossfire and as he turns the key all the way the engine will not start...so i reset the computer and the car starts for a breif second and shuts back off and will not start again unless i reset it... does anybody know what the problem could be because autoshops it was sent to by tow truck can not figure out the problem and chrysler dealership wants $150 just to figure out the problem...could it be the rellay control module or the oxygen sensor?

 

Is it throwing a CEL? You need to get the DTC read out. I had/have a problem with my crank positon sensor that causes the car not to start. Sometimes it just seems to start at the end of the cranking and doesnt catch. It always throws a CEL when it does this or it doesnt start. P0335.
The crank position sensor is on the back of the engine by the bell housing, drivers side. You could try unplugging it and plugging it back in and see if it makes any difference. Mine seems to have an intermittant connection/contact problem still and occaisionally wont start unless I fiddle with the connector.

p.s. make sure the engine is COLD.

 

There's been several relay control module failures it seems with the 04's and most have similar symptoms.

Relay Control Module Failure
1) All accessories are operable when the key is turned to the ON position with the exception of the fuel pump
2) When the key is toggled to the START position the starter does not engage
3) Mostly happens when the engine is at running temperature
4) Can sometimes be temporarily remedied by rapping the side of the RCM containment housing with like the handle of a screwdriver

Compare these symptoms to what is happening to your brothers car. If the starter engages and the engine turns over but does not start then most likely the problem is elsewhere.

Hope this helps, you may also wanna do a search on Mystery No Start or Relay Control Module or Crank Position Sensor for more info.

Good Luck !

 

"Can sometimes be temporarily remedied by rapping the side of the RCM containment housing..."

Do you really think rapping to the containment housing is gonna fix the problem?? I mean i'm a fan of Ice T but come on!

 

Noooooo, maybe you misunderstood, if you're stranded on the side of the road, work or whatever, sometimes giving the containment a good whack will get you home or to the dealer. It is definetly not a fix !!!
The operative word here is "Temporarily" !
Now, ask me how I know this ???

 

Oh, I thought you wanted us to Rap, (you know) spill some words to fix the problem.

 

Just as " dancing "... white boy can't "rap" !!! Geez !

 

The problems with this thread are worse than the problems with your car!

 

yep!!

 

You have to admit though...it does bring up some interesting mental images! Right now I have the one where Vanilla Ice is dropping some rhymes under his hood on the side of the expressway, silly dance and all!

 

Just saw this problem on the forum yesterday. I'm gonna sound like guys' that have been here forever...but a quick search turned up the following.

Has the part number you need and what it should cost you.
good luck with the fix!
