MG ZT+ CDTI non starter
Hello all you knowledgeable types out there, a friend has been presented with an above MG in what appears to be a good condition.
But it won't start. It's had no battery for about 9 months and when we came to start it today, it wouldn't, and both the fuel pumps were not running. Lights and wipers worked fine. Is this a symptom of "immobiliser needing help" or is it something I can fix myself. I've tried using TOAF to see if there's anything obvious but it won't talk to the ECU even though it will show errors in other modules. Any ideas? Mick |

Hi Mick,
There could be any number of reasons for this. First off, does the car have the ECU fitted (and plugged in etc)? Have you checked all the fuses? (If the immobiliser and ECU cannot talk, the immobiliser state immobilised) If you are near Hampshire, I may be able to help, I have a full set of spares for the diesel electronics so can help identify any issues. Chris

Thanks Chris, the car was running fine 9 months ago, I've driven it myself, but the battery died and got chucked.
Maybe attempting to start it with a duff battery fried the immobiliser? Mick |

If it has been sat for 9 months could it be that the plenums are blocked and now flooded. That'll knock out the ECU.

ECU has been for a swim, fuel pump relay output is the first thing to go

OK, plenum dry as a bone, but I suppose the only way to tell is to look for a tide mark on the circuit board. That'll have to wait until next week.
Any other ideas? Mick |

It only takes a few minutes to remove the ECU to have a quick look at it, but a good indicator of any past flooding, is the pollen filter if it has been in there a while.
