Good specialist in Northwest

Recommended Posts

I have a problem with my 350z and it wont start. AA think its ECU related so needs to go into a garage.

 

Are there any good specialists in the NW who have the correct equipment and will properally diagnose the problem instead of just swapping out ECU's etc first because its easier (ive had this in the past!)?

 

If there are no suitable garages, it'll have to go into Chorley Nissan.

 

Thanks Andy

That wont work, that reset only removes a MIL light if one is displayed. That is not the issue with my car.

 

Thanks for the help though :)

 

 

But how do you know that especially when you state the AA only think its ecu related. An ecu failure is very rare on these cars. The reset does not only remove the light. ;) If this was my car i would at least be trying an ecu reset as outlined, you have nothing to lose and only takes a few minutes. :)

 

Similar case here

The ECU reset wont work. When the ignition is to 'ON' the MIL light which is used in your procedure is not shown on the dash. Therefore it is not visable to flash etc.

 

It would appear the body ECU which controls everything bar the engine is fine, and for some reason the ECU for the engine is not enabled - either because it is broken, or more likely because it has not got the OK from the immobiliser to work.

+1 sounds like immobiliser, did you try the spare key?

Have tried both keys. No luck

Keep us posted what Nissan comes back with, I wouldnt hand it in there now to be honest but if you are under some sort of warranty it makes sense?

 

Not sure what a new ECU will set you back if it's fried, make sure to find the problem before you (Nissan) swap it out for a new one. Only thing I can think of is that it got shorted with etc water or corrosion on the harness connection but that’s a bit of a chance. Do you have a good friend that could borrow you an Z ECU to test with? :teeth: (could be dangerous I suppose...)
