Check engine light comes on after being deleted, before even starting
Left negative battery cable off for almost 24 hours with EFI fuse pulled and as soon as I put the key in and turned key to ON position (not cranking) the check engine light came on.
I thought OBD1 should not store code/s until it runs for a while. Is this correct?

Thats normal...
Also there is no need to have the battery cable and EFI fuse out for that long.
30-45 seconds tops and it deletes all codes.
is your best friend when it comes to questions like these.
