Check whether the ground on the thermostat housing is loose or corroded.

Next check whether hood fuse 44 or dash fuses 31 or 13 are loose.

oh thanks for the help. ill try to sand the terminal see how it goes. can i also ask you where you get that picture from that seem kind of helpful for me to track on the engine harness.

also can the wire inside the engine harness is cut or something? but from looking from the housing of the harness it never been touch or anything.
