7mgte issues need help doing diag

Just a thought, with the FP bridge in place & ign. on can you hear the fuel pump running & the regulator on the fuel rail blowing off excess (hissing sound)?

If not then the pump or it's wiring are an issue. You said the pump relay gets really hot, I'm not sure how hot but if it's overheating then it could either be the pump drawing excess current or a dodgy relay, the results of the wire bridge would suggest which.
