I think you will find that it's the ECT. You have all the symptoms of a bad one. Post back if that doesn't cure it.

Have you thrown a timing light on it? I would do that before replacing the fuel pump. You did say that you had good pressure. Have you checked each plug wire to make sure that all cylinders are firing? I have read other posts where they found that was the issue.
