Hi, new to the forum, I have a 2000 V-6 with 90k on it. The battery died at school and it sat for a month. With new battery, now there are no indicator lights in the key on position, check engine, abs, service etc. checked the OBDII port for codes and there are none but some of the systems indicators are blinking as if they had been cleared and are waiting to reset. Now It can't pass inspection with out functioning CEL? any ideas?

Thank you in advance for any advice.
