where can i get a high pressure spring?
Won't help you.
The high pressure spring sets the MAXIMUM oil pressure. It will not raise you lower oil pressure at idle.
The only caveat is if the pressure relief valve is sticky, taking it apart to install a new spring might loosen it up and get it working. But it won't be the spring that fixed it. There was a batch of oil pumps a few years back that had this problem and I think it was Melling pumps too.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
