opel corsa problem

whelan1

we have an 03 opel corsa petrol 3 door ... having terrible problems getting it to start , the lights on the dash start dancing ... engine will turn but wont start , when the lights stop dancing it will start , any ideas?

Do the lights stay on for long, or just few seconds?
Which of the lights "dance"

It is recommended to wait until all warnings are off before starting the engine.

its all the engine warning lights , they could dance for asges , then come back to the car a few minutes later and try again , they wont be "dancin" and it will staert, we brought it to morrows in bessbrook and they put the computer on it , it didnt show any problems , while the lights are dancing there is a clicking noise coming from behind the battery. all connections where cleaned behind the dash

I would suggest checking al the fuses, cables etc, reconecting the battery and see if there is any improvement...
As computer doesn't read any faults i would look into all connections.
I am not a mechanic but had plenty of faulty cars (fiats...) in the past...

thanks, is it true if itis the ecu , that you have to buy aa new one

Changing the ECU is the very last option, as it is expensive.
Anyway Opel service should help you to determine where the fault comes from.
Good luck, I hope someone will sort this out for you the cheaper way.
