Hi, went to my KZN130 surf earlier today after not driving it for a couple of weeks only to find it wont start.
When the imobiliser is turned off the engine cranks if anything faster than normal but does not start. I Have noticed that the glow plug & check engine light do not come on anymore.
Tried the diagnostic port in the engine bay to read fault codes but get no flashes at all from engine light.
Tried checking the signal voltage going the glow plug relay, when the ignition is turned on there is only around 3v going the the coil of the relay.
From reading other posts it is looking like ECU failure but want to be sure before sending it for repair.
I have been trying to check the ECU is being powered and have found the following so far; With the 3 connectors removed from the ECU I find that I have 12v measuring between terminal A-1 (BATT) and terminal C-14 (Earth) as expected, but I do not have any voltage with the ignition on when measuring from terminal A-2, A-12 or A-13 to C-14.
I believe I should have 12v with the ignition on at A-2, A-12 & A-13 to C-14 is this correct?
Any thoughts, help and advice would be greatly appreciated.
