2003 vtec, installed a FH020AA regulator and while letting it idle so I could ensure it was charging the fuel pump quit, I left it alone for awhile and came back a few hours later and the fuel pump worked again but only for a minute or two, it doesn’t sound weak when it did turn on but I check the plug at the pump and it’s reading 11-12v when i turn the key on, is this a faulty pump?
