Car sometimes won't start please help
 

hello everyone, new to this forum & also a new owner to a 2004 crossfire.

unfortunately I am already having issues with this car I would REALLY appreciate any help.

I noticed that when I turn the key , the car seems to have a bit of a sluggish start-up. Everything was all fine and well until yesterday when I was in the middle of running errands, the car wouldn't start. (the car wouldn't even crank over, however from what I remember, all of my interior electronics were working). I tried starting it about 5 times, no luck! so I decided to just wait a few minutes... when I turned the key, slowly but surely the car turned on! however my BAS ESP light remained on for a few minutes.

the ride home went well , I was just hoping the car wouldn't die on me during the trip home. I successfully made it home to my garage.

SO THIS MORNING when I turned the key... same thing happened! the car wouldn't even crank over. my BREAK WEAR INDICATOR , COOLANT LIGHT , & BAS ESP LIGHT were on when I was trying to turn the car on. (all of my electronics were working for the first few cranks but then eventually died out)

I have the same issue, today I drove to work About 10 miles when I backed up into my parking spot turned off the car then I noticed I needed to move it back farther when I got in and nothing no crank no start. I waited 30 minutes and it started right up,. I had this happen before same thing I waited 15 and minutes and it started again. So I figured it was the rcm and sent it to tighe to replace coils and solder where it needed. Is it that skreem unit????I don't want to left on the road stranded.

This is where you need a good scanner that can read the internal modules (my Autel Diaglink can but need to use a slk320 setting) to find out what the car thinks the issue its. My new to me 04 Coupe had a constant BAS/ESP light. Scanner said many things but came down to the Brake Pressure Switch #1. Replaced it and light is now off.

:) Sounds like your CPS is going. Use a BOSCH replacement unit only. Those who use a generic find out soon enough they do not work right. :)

Yes, the CPS can fail when it gets hot, after it cools a bit it will work again. As Graphite Ghost stated, use only Bosch.

Re: Car sometimes won't start please help
 

OTOH a CPS will not keep it from cranking, just starting. Turn to start and nothing when hot but works when cools down and no codes is likely the starter solenoid. Usually helps to open the hood for a few minutes. How hot is the coolant running ?

Re: Car sometimes won't start please help
 

Concur with Graphtghost. The CPS ( Crankshaft Position Sensor) is the likely problem. click the below attachment for how to info and buy no other than the Bosch replacement CPS.

Re: Car sometimes won't start please help
 

The OP contradicts himself in the original post. If indeed the car doesn't crank you are correct, may also be a pulse module problem among other things.

Re: Car sometimes won't start please help
 

Agree and why a Bosch CPS is in my spare parts kit What is needed is to troubleshoot with a trouble light or DVM. I'd start with "is the solenoid getting power when nada" ?

Re: Car sometimes won't start please help
 

Post 2 is not about a crank sensor, it's RCM (probably), Pulse module (possible), starter/solenoid (doubtful), or flaky battery (maybe but I still say RCM).
Crank sensors do not inhibit starter engagement.

How the hell did we miss the cry for help in post 1?

Are we getting as useless as Ford Ranger Forums? No one even gave BAD advice to that guy.

Re: Car sometimes won't start please help
 

The bottom line for all: nothing beats proper troubleshooting. So far I have not see one mention of what the battery voltage was much less use of a proper scan tool.
Without proper information might get better luck on the psychic hot line.

The solenoid is a triage point can either point backwards (battery, electronics) or forward (solenoid, starter) but is the place I would start for nothing when hot (and without a coolant temp we do not know how hot), ok when cools down. The real answer to both is "insufficient data".

Know there are those here who are both experienced and knowledgeable but suspect auto shop is no longer taught in high school. Unfortunately those who are are rapidly ageing out and will not be around for long. Then what ?
