P0380 is a circut fault/engine cranked on cold GP's. Will reset itself after 3 cold/hot/cold run cycles if doesnt reoccur during that time. If the CEL is constantly lit, a fault is reoccuring.

If relay powers GP's you might want to see if it cuts out too early after starting. Should stay on for ~2 min after a cold start. If so, need to determine if is relay or K40.
