I have a crossfire 3.2l,

It has very intermittent cranking. One minute theres no cranking at all the next minute it will start then die then start and will run the next 10 times.

There are several bus codes stored in the vehicle -
- Engine CAN Message missing
- No CAN communication with PCM
- No CAN communication with CAB
- No CAN communication with TCM
- CAN Malfunction

If anyone could shed any light that would be great or has anyone come across this?

 

The stored messages may have no bearing on the condition, try disconnecting the negative battery terminal for 10 minutes or so, turn the key to on while disconnected, then back off.
This should reset all the stored codes.
Then do the RCM repair - https://www.crossfireforum.org/forum...rol-module.pdf

 

i know of this problem, however i have swapped the RCM over off another crossfire which is working fine. and no change.

 

Anyone else shed any light? Or expirenced anything like this before?

 

According to what the code messages are telling us you have an intermittent loss of continuity at one of the connectors in the main line you're going to have to go connector by connector with a can of contact cleaner and systematically disconnect clean and reconnect each one. A wiring schematic is available on this forum to assist you, I know it's a lot of work but it's the logical course of action that needs to be taken. I believe if you search the how to section under documentation you will find the wiring schematic in the service manual. Success is achieved by perseverance. Just a suggestion but a good place to start maybe the CAN bus connection itself, and be sure to disconnect the battery before you do this you don't want any arching going on while you are disconnecting and reconnecting the connectors, good luck and I hope you solve your problem.
