If your IR was renewed on multi engine aircraft then you have a current ME/IR, so yes you can claim a current SPA ME/IR on the CV even when the MEP has lapsed (it is the same as if you had done a revalidation in the sim, you would have a current SPA ME/IR but not a current MEP).
However without a current MEP you may only exercise the IR privileges on a single (assuming your SEP is current).
However the requirement to start your first multi crew type rating is a current SPA ME/IR, as such you will not require the MEP to be current if you are fortunate enough to get a job on a multi crew type.
