corsa ecu?

A replacement engine was fitted, by my Granddad, to my Corsa 1.4, sri 16 valve (Kreg 2000), as previous engine 'big ends' had broke.

Was collected after completion (car has been off the road for 7 months by this time) and started first time.(Revs were stuck at 10000 rpm on idling but thought this was just needing adjustment.)

Drove 5 miles and stopped for meal. Started up ok after 30 mins break but after 1 mile engine lost power and eventually stopped and refused to start up again. Dashboard lights were on but car would not even turn over.

Only warning light showing is Yellow (engine block) light but this showed when car originally broke down.

Strangely enough the symptoms of this breakdown were exactly similar to original breakdown symptoms!

No other ECU lights or codes showing.

Also we later found out that although the engine supplier had verified that the engine was a 1.4 Sri I have been told by my Granddad that it is a 1.6!!

What would you think the problem is?

If this is for a Corsa C then the answer is no. The ECU is linked to the immobiliser system via a rolling code. The old on-car ECU must be 'reset' to allow a new ECU to be fiited. A second hand unit also needs to have had this function carried out so that it bahaves as a clean ECU.

The downside is that this is usually done with the Vauxhall Tech-2 system held by the dealers (and some specialists) as it needs to reflash the ECU with the correct software for your car. You will also need the immobiliser code (found on the pass card).

Not sure if this applies to the previous Corsas, but would imagine that the newer ones are similar if not harder to replace.

Damn Corsa!
