Hi everyone.
My corsa b 1999 1.2 16v wont start! It turns over but just wont come to life. Mechanic syas it looks like the ecu has gone.
Not sure on what to do. Apparently one common issue is they have a ECU output problem to crankshaft position sensor running at low voltage.Would this give me my symptoms?if so how could i check this and secondly how would i remedy it? New ecu, key and transponder? or is there a simpler option?
Hope theirs some smart peeps to help me out coz auto electrical issues are not my forte!! lol
Thanks in advance.
