Re: Crossfire won't start
Hi,
So you wanted a recap of exactly what has happened to the car so far.
First thing I think it is important to tell you. We took the car to have it's after market immobiliser disabled because the key fob you used to disarm it wasn't working properly. Also had a brand new battery in January.
Took it for new tyres at the garage where we have our MOTs done. They couldn't drive it into the workshop because it wouldn't start so they pushed it into the workshop. There was no feed to the starter motor. We took them the second key in case there was something wrong with the original. (the car was car jacked with the key so had a second key coded to it). We called recovery who also couldn't do anything with it so had it towed to a friendly auto electrician. They said they tested everything they could think of and concluded the ECU must be faulty. Lots of people in the UK advertise ECU testing, not 100% sure what they do.
ECU came back fine and working. Refitted it to car, got auto electrician to check all electrical connectors and several were resoldered including the ones marked on the RCM post as being common issues. Reconnected anything that had been disconnected and the car would crank for 2 or 3 seconds then nothing until you disconnected and reconnected the battery. Battery was fully charged before the auto electrician arrived and was connected to another car with jump leads at some points (from what Paul Noyce has told me!)
I took over because I was fed up of my mum complaining about not having her car. We disconnected the RCM following advice on here to make sure the soldering was ok. Board looks a little discoloured at the new solder points but other than that everything was ok. Took the RCM back to the car, reconnected it, hooked the car up to my van with jump leads and nothing. All the lights come on on the dash but there is not even a flutter from the engine, just the wurring sound which as I mentioned could have been there before! Ignition lights don't go out at all they are constantly on, spanner shows to say it is past it's service mileage but not fault codes are logged.
My Dad is absolutely convinced it is not the battery.

It sounds to me like the immobilizer is doing it's job! What does the shop that put the immobilizer in have to say?
Yea, it probably is not the battery....
This is one for Rudy !

Re: Crossfire won't start
Hi,
Definitely not the battery, tried several other suitable batteries with nothing. I'm not sure if the after market one was completely removed or just disabled, so I've contacted them. The aftermarket one was fitted by a different auto electrician to the one who disabled it but both of them have looked at the car since the issue arrived. It was removed about 2 moms before it wouldn't start

Re: Crossfire won't start
Just checked the the electrician that removed it, he completely bypassed the aftermarket immobiliser and reconnected the circuit. Having had 2 of them check connectors you'd like one of them may have spotted something

Re: Crossfire won't start
So I'm down at the car now. Disconnected and reconnected the battery and hooked up jump leads. Tried one of the skreem fixes I saw and held both buttons in on the key. It fired but cut out pretty much straight away. I'm now sat in it connected to another car with the dash lights on to see if I can get it to start and stay started. Hope I don't fry the ecu like I've heard others talk about!

Dad is pretty sure it's not the battery. He thinks that because it cranks for 2 or 3 seconds and then stops and will only do it again when you disconnect and reconnect the battery it won't be the battery. I have instructed him to try disconnecting the battery and charge it up properly. He is after all assuming it wouldn't be the simplest thing, which it could be!

Re: Crossfire won't start
Hi Guys,
I know it's been a while but i thought i would update you on the car! Having told my dad it would be the skreem module he decided to tow it to a local chrysler dealer for a diagnosis. I was right and they diagnosed a failed skreem module. Having waited 6 weeks for the part they could not get one in so i set about looking for one myself. The scrap yard didn't have one. I contacted mopar in America but they said they couldn't do one as you have to return the part and they wouldn't let me ship the faulty one to them. I then ordered one from onsalejeepparts.com and they let me pay a deposit on my old one until it is returned. Haven't got the new one yet but provided i do i got it for £450 which is quite a saving on the chrysler dealer part price! So hopefully my mum's car will be back on the road soon!
