Okay so I came home from work and showered and whatnot and went to go leave to eat dinner. I went out and turned the key on so the pump will build up but it didn't whine or anything and on top off that it flashed some error code. P0573 or something close to that. And now my ammeter is showing low voltage. I need help ASAP. FASS pump has new filters and had truck plugged in last night. Thanks in advance guys.
