    remove the pcm relay.as you are looking at the fuse box it is the top right side.have replaced tons of these for the exact same symptom.some times a visual inspection will tell you it's bad/the terminals will be green or corroded.other times you cannot see anything wrong with it but it has an internal fault.good luck.
