Have you checked to make sure you get a signal calling for it to engage?

x2 sounds like your not getting the signal the relay needs to click on. thats why when you jump it out it works.

Have you put any gauges on it?

Yes I have put guages on it and it all looks fine . So what sends the signal for it to kick on?

Does anyone know where I could find a wiring diagram?

Are you having any more electrical problems like tach or blinkers not working? Mine was doing that and turned out to be a bad connection on the ECM fuse under the hood.
