(1) Answer
Pretty simple test > Test for battery voltage present for 2 seconds on both wires at the inertia switch when key is turned on .. (Test one of the wires for battery voltage - cycle key again to check the other wire) .. IF voltage IS present on both of those wires - no further testing is required ... Replace the fuel pump!!
