Hi Ian

Where did you connect the voltmeter?
Don't worry about system voltage readings while the starter is spinning.
Measure the battery at the battery, and get 12.6 Volts engine off
and 14.0 Volts engine running.

Is there voltage at Fuse 1 and 11 when it fails to start?
Measure Fuse 1 and 11 as discussed.
How much current draw for each pump?
Read DC millivolts at the top legs of the ATC fuses and use the voltage drop
chart to get DC Current values.

Bill
