I could use some help tracking down these fault codes. First one says it's "Power relay coil open" but none of the relays in the fuse box say power relay. Also tried switching them all around and no difference. Anyone know where the power relay is? The other code I can't identify. Tried clearing the codes, they didn't come back but the MIL is still showing on the display fault page saying something about MIL signal wire. I have no MIL on the dash though. It cranks fine, I have spark and fuel to the EPR. I could really use a wiring diagram. Has anyone run across this before? Ideas?
