ECM causing power drain

I've narrowed a drain on my camaro's battery down to the ECM. Has anyone ever had this problem and is it fixable?

Re: ECM causing power drain

yes, i have seen a few ECMs stay powered up after the key was turned off.
check the switched power wires going to the ECM, if they do not have power with the key off, replace the ECM.
