Would your method not bypass the inertia switch?
Neil.
edit - I also would have expected the wiring underneath the car to be in the worst condition?
I would measure the earth and if its poor cos teh switch is sat in water, i would renew it and move it up to teh boot with fresh wire. Surprisingly, the wiring at the pump is usually pretty good and teh actual problem with the fuel pump circuit starts at the fuse box and worsens at teh boot connector. Wet can be better than "Damp" for wiring.
