So I got the replacement IPM installed it. Made absolutely no difference. The fuel pump relay is still clicking like crazy, none of the gauges (dash) are working, and it won't start. Lights are now normal and everything else seems to be normal as well. The only thing that wasn't changed was the FCU which I transferred over from the original IPM. Can anyone tell me what the FCU controls, or advise where I might find that information?

Cheers, and thanks!
