Got in the car this morning, turned the key on to start the Eng. The Eng. started but shut right off. Tried it again, Eng. started an shut down again, third time it started an ran fine, ran ok the rest of the day. Wonder what that was all about ? Any body have any ideas.

 

Check search feature cps sensor maybe, easy diy fix,,,,,,, are maybe this https://www.crossfireforum.org/forum...-no-start.html

 

Another user just had the RCM problem yesterday..5 of the 6 solder terminals were crap. Does the cps throw a CEL when it starts acting up?

 

Does the cps throw a CEL when it starts acting up? Sorry, i'm new 2 this, what does CPS & CEL stand 4

 

CPS - Crank Position Sensor
CEL - Check Engine Light

CPS will give a code

Don't rule out the fuel filter/pump. Fuel may have drained back into the tank and car finally ran once fuel was pumped back up to the engine.


Let us know if it happens again.

 

Since your the "go to man" on these, would a cold engine act up with the RCM problem? Seems anytime I've read of issues showing up it was "while driving down the road..."

 

Thanks. No check Eng. Light came on.

 

Went to start the car, it started & shut right down, it did that a couple of times, then i had nothing, like the battery was dead, i took the positive cable off & touched it back on the battery & got no spark, did that a couple of times & finally got a spark, then it would turn over & run. It ran good all the way home ( 25 miles ) Backed in the garage, shut it down, went to start it again, it started up but shut down, tried the second time, it started & kept running. I don't get it ? Any help.

 

Did you take care of the CPS and/or Relay Control Module(RCM)???? The CPS will USUALLY throw a CEL and P0335 error....

 

The CEL did not come on

 

did you put and OBD II reader on it and see if there were any codes stored???

 

I don't have one, I'll have to see if i can locate somebody with one Will i get codes, even if the cel didn't come on ?

 

it is possible....Autozone, and probably others, will read the codes for you for free... they will not clear them..

 

I tried Autozone, on one other ocation, they wont check it if the cel is not on.

 

Had problem similar to this on Friday. Car cranked, wouldn't start. Finally got it started and drove 25 miles home. CEL came on. Knew it was the CPS. Brought it to the dealer on Monday, got it back yesterday. Was the CPS, they replaced under extended warranty. Car has just under 70,000 miles on it. Had 2011 Jeep Wrangler with only 560 miles as my loaner for the three days they had my car.

 

I took out the RCM to day an soderd the three prongs put it back. Same problem. Cranks over, Stops & starts about the third time. I guess i'll change the CPS now & see if that does it. The CEL never came on. I don't get it, because i thought if the CPS goes bad the CEL would come on.

 

Did you check the relay contacts while you were soldering the RCM?

 

Mrmiata, when you say check the contacts, check them for what? & how?
Got in the car to day, it turned over & started & shut right down, the second try it started up & stayed running. It will run fine with no problems, till you shut it off, & try to restart it again, then it's the same problem. Some times when i try to start it, it will have nothing, like the battery is dead, then what i have to do is disconnect the battery cable, & keep touching it on the termanal untill i get a good spark, the it will start, & keep running, like it resets a relay or something.
I'm telling you it's driving me NUTS. Any ideas ?? Thanks 4 getting back with any help. Ron.

 

Make sure the contact points are clean and not arced out..believe there are three of them on it.."gently" check them to insure the contacts move freely (spring pressured to keep open if I'm not mistaken in my minds eye)

 

Yup, they are all (5 of them) Fine. I think i have figured out what my problem is. About 2 month's ago i orderd a new key fob, that was not programed right, it would start, but not right, then one day i hit the panic alarm by mistake & could not shut it off, so i put it in the ignition & tried to start the car & that shut the alarm off. Looking back, thats when all my problems started. I think the computer thought someone was trying to steal the car, & it did something to the chip in the fob. Just went out with my old key fob & it works fine. It might take sometime to reognize this key fob, But at least it's not shutting down where i have to disconnect the battery to start it again. I hope this is it.
Thank's for your help & info. Ron.
