Reed Valve Error P1477 (replaced pump already!)

2005 Cooper S

I'm getting the 1477 Reed Valve error (switch not opening) and replaced the pump but the it is still not opening and still throwing the code . Dealer thinks there is probably a frayed wire or a ground fault happening somewhere down the line but its tough to track down.

Anyone had this problem before? Is there a common problem area to start looking?

Thanks!
