Fuel pump power loss

[Adrian07]

Hi, I'm sorry if this is long winded explanation, but I want to get all the info out.

BA xr6 turbo ute 2005 6 speed manual. I replaced the fuel pump with a 525ltr in a larger FG bucket

Ran a fused 10g wire direct to battery and second relay to trigger from factory relay. Tested pump and started car fine, idled for approx half hour and switched it off, all was good. Disconnected battery to do some head unit work and when I reconnected the unit, the fuel pump now does not trigger.

 

I checked power to relay at ignition is fine. Jumped relay and still no power. 

Inertia switch is getting power at ignition. Jumped Inertia switch and still no power.

So something is wrong somewhere between Inertia switch and pump?

 

When I jump the second relay that I installed, the pump runs fine

 

All fuses are good 

Factory relay is good

Secondary relay is good

Pump is good 

Inertia switch is good

 

Question is, does wiring go direct from Inertia switch to pump? Or is there another break between?

 

Pulling my hair out

 

Thanks in advance
