A mate of mine is having problems with his Z by the looks of it,it keeps blowing the ecu the problem he had at first was no spark so he changed crank angle sensor and i cannot remember what else but i know the ptu has not been changed and it is a s1.So back to it so he brought a mines ecu off ebay and it worked for a while well till last night when i get a phone call same again no spark so he borrowed my ecu again and the car started straight away so what are the chances of 2 faulty ecu's and is there anything we can check to stop this happening the car is a 92 tt lwb jap import.

anyone.

What happens when you put his old ECU in your car ?

What voltage is it charging at? If the alternator/regulator is knackered it could be frying voltage-sensitive chips in the ECU? Just a thought :) Does it have a habit of blowing bulbs or anything?

check the earths on the engine and ecu first off

i can't put his ecu in mine as his is manuel and mine is an auto.Vern no bulbs blown or anything.It all started after it come back from the bodyshop after a re-spray yhe guy said the battery had gone flat and he had sprayed the air filter with the stuff in a can which helps start cars cannot remember the name and after a while battery went dead so he put a boost pack on it to fire it up and it worked but don't know if this has got anything to do with it but it all startred after this and yes you guessed it it fooked the maf up so it has been replaced.

might be talking rubbish but have you checked the ptu to make sure it's working? from what i've read and experienced it can cause no ignition until it cools down. might be why it worked when you plugged your ecu in.

EasyStart - shouldn't do any harm, it's kinda like aerosol petrol.

 

Like someone said, get him to check the voltage at the battery, if it's more than 14.8v then you have a regulator/alternator problem.
