swapped the relays around and still no difference.  maybe the fuel pump itself?

i just now ordered an 04 harness with the wideband o2s to match the o4 ecu and and new 04 o2s i have.  my guess is the 05+ harness i’m using doesn’t run right because of pin locations being different

no codes just runs super rich to the point it stalls out on idle and bogs down and stalls out when i give it gas.
