Wonder if someone can assist with an issue I'm having with a friends corsa z10xep (04 plate ).

It was running ok on Friday. Left over weekend and on Sunday cut out after starting.
On checking there was no engine management or immobilizer lights coming on at all ( all other dash lights work ) when key turned and unable to connect to ecu with a code reader.
However if you disconnect the earth lead to the ecu and re-connect the lights come on and car will start.

Lock the car and leave it ten/fifteen minutes and the two lights dont illuminate and wont start again.

Had a look in the haynes manual but there seems to be no wiring diagram for the injection system/bcm systems.
