Is there a short anywhere in the wiring harness? Have you inspected the harness? What happens when you completely disconnect the PCM from the vehicle? Does the fuse still blow? If it does not blow, then you probably have a faulty PCM.

Ah yup... Sorry, I had missed the edit that you made. Stinks to find that you have a faulty pump though.. Good luck with the repair!
