Finally (after 3 months!!) got the problem resolved, but had to replace the IPDM and then BCM. Thanks to ZMANALEX for supplying these at half Nissan prices.

Still haven't got this problem resolved. I managed to get this explanation from the garage: 'Checked for not starting found NATS code logged, cleared code , no difference, removed IPDM- and checked connections - ok, charged battery, - requires new battery. Carried out further checks using consult and found IPDM not showing on control unit links. Carried out wiring and CAN communication checks - seem to be ok , possible internal fault in IPDM would need to try another IPDM first , part number for IPDM is 284B7 AL51B price - 1155 +vat.' I am of course getting the battery replaced (£60.00 + vat fitted) but do you think this is a reasonable diagnosis? Any advice for what else they should try or if not any idea where I can get an IPDM any cheaper? Am reluctant to fork out all this money for a 'possible internal fault in IPDM'. Many thanks for any help! Dave

Thanks for the advice so far! The car is stuck in the garage, I assume they have tried a new battery but I will double check. Also will try and get some more technical details and post them. Wish I had replaced the battery sooner . I'm in N.Ireland - I'm guessing thats not near any of you!

I have had a 2003 Japanese import 350Z for a year - great car! No problems until 3 weeks ago a warning light came up on dash, 'possible engine management problem'. Car running fine but thought I better get it checked out so took to local auto electrics garage to run diagnostics. Unfortunately the battery died in the middle of test (I knew was dodgy and was due to be replaced the next week) and whatever they did could not get the car started again. Had to get it towed to Nissan dealer and after a week they got new codes from Japan (Nissan technical?) and reprogramed keys etc - still won't start, but headlights come on when try. Now they say is a communication problem and either the IPDM (?) or ECU may have blown (some error codes suggest something to do with jump stating which might have caused the problem). They say each of these cost >£1000 and will be hard to source Japanese version. I don't know what to do now so any help/advice from you guys would be much appreciated!!
