Log in and using the search option up in the header, search overload protection relay or OVP or overload protection relay. See if any of those threads relate to your issue.

If you do not know for sure that the OVP relay has been replaced and is not the original one, I rec you spend $80 for one. Not just check the fuse(s) in it, but buy a new one. As that thing fails, all kinds of intermitant electrical issues arise. When it dies, your car does not run at all.

Did you check for error codes??

After that, then test MAS relay.
