Hi,
I have a problem with a Chevrolet Blazer model year 2000 with 4.3 engine,DELCO ECU.
The car is starts but sometimes not.
The PASSLOCK system is good,the problem is not with the PASSLOCK.
The car has a remote control fob too,and sometimes the car forget the remote control fob.
So i need to re-learn/sync the remote fob with the car.
After that i need to press OPEN button to disarm the security.
If i not pressing the OPEN button the SECURITY light stay lit,and the car start then stops.
So i need to remove immo from the ECU because this system is not stable.
I saw in CARLABIMMO forum,they can remove immo from flash.
Have anybody a subscription there?
Or have anybody idea how to disable the immo from ECU?
I like to pay for information or solution. Or if someone has a SUBSCRIPTION to CARLABIMMO I would like to pay for help.

Thank you!
