Re: computer problem in 89 300z turbo
well first of all you should download the FSM for it...
http://www.phatg20.net/modules.php?n...ownload&cid=67 secondly, have you checked to see if the ecu is operational? you can do this by pulling it off of the pass. kickpanel, turning the ignition key to 'on' and turning the selector screw on the ecu fully clockwise... if you see led's blinking then the ecu should be working... after warming the car up, do this again, and wait for the led's to flash 3 times (mode 3) then turn the screw fully counterclockwise... after this wait for the codes to roll.. the red led= a value of 10, eg. 3 flashes =30, then followed by the green led flashes which equal a value of 1... if you get a code '31' then the ecu is cooked... the rest of the codes and a better description of the diagnostic procedure is in the 'EFEC' section... any further questions i'd be happy to answer
