Can we rewind to the very start.... what caused the battery to go flat?

Also, has a different ECU been tried?

Best that the OP answers this but to move on I understand the car was left unused  standing for some time  & battery was taken off to be charged . . but Paul will confirm this .

Can another ECU just be installed ?  or does it have to be Tech 2'd to the car ?

[sjc]

To swap the ECU you'd either need just the ECU and a Tech2 or an ECU with paired chip reader and key - the key doesn't have to be in the ignition, it just has to be next to the chip reader, so it can be done without too much dismantling for the purpose of a test.

This would be my next move.  Most everything else has been tried.

Thanks all, battery went flat because lack of use over winter, charged up ,startd perfectly round block couple of times,no probs,only when i tried day or so later did problems begin. To try ECU change if i read correctly i need ECU,ignition chip reader and keys.Looked on ebay and there is a set on there for £150 umm..... bit of a gamble anyone got any ideas?

[sjc]

Oh man, that sucks - it ran ok then went t!t$ up 

Post a wanted ad in parts saying you need a loan with possible purchase (i.e. if it sorts the problem).

Another one on ebay for £50, has the chip alone (without a key) but that's all you need.  There is a mobile number to phone - I'd make sure they are already paired and not some random parts thrown together.

If you search using "vauxhall omega 2.6 ecu -transmission -abs", it turns up a few around £70 too.

Albitz  loan service can loan these parts for you to try.Only possible problem is that they are from a 3.2
Would need someone to confirm that the 3.2 ecu will be ok to plug into a 2.6.

Would imagine maps will be slightly out but would still run the engine good enough to determine if it's the ECU at fault.

If  i earth ecu to neg. on battery using a spanner the clicking stops but car would not start,as said before only way to trick car to start  is to disconnect/re-connect one of the main looms on the ecu but then only 1100rpm and gets hot quickly i know this is getting boring but i really am giving it a go so thanks for all your patience.
It seems to me that something is sending a message to ecu which is causing problem?

Could it be earthing problem and immobilaiser fault at the same time

[Toledodude1973]

Thanks 3.2 seem to have different part numbers, the cheapo one i looked at on ebay was also wrong numbers, there is another one for £70 odd or best offer so might take that route(cheaper than garage)
Did mess with earth on ECU to try things but even completely separate earth didn't cure problem
ECU change seems next move as auto electric technician not go back to me i know its the w/e but a text would suffice
cheers everyone on here

Why? Albs has agreed to loan you an ECU set ^^^^^^^^^ reply #95

[Toledodude1973]

Do you think it will do the business Rob i just thought when SJC said about mapping thing? it might not work, i'll PM Albitz he has been a superb help throughout along with lots of others cheers

[albitz]

We can only but try and see if it helps.Reading this thread has just reminded me - I now need to go and remove the relevant bits from the car before it gets too dark.

[Toledodude1973]

OOF is working at its best true Omega loyalists! thanks Albitz sent PM
