After analyzing the schematic diagram the DME relay PIN 86 and 30 should be hot at all time (12 V) coming from the power distribution, and when switch on, The DME PIN 27 sends a signal to PIN 85 of the DME relay to bridge PIN 30 and 87 then sends a 12V to fuel pump relay PIN 86 . While the switch is still on, DME PIN 63 gives a signal to fuel pump relay PIN 85 to bridge PIN 30 and 87 and sends a 12 V to fuse #18 15A to run the fuel pump motor. With this schematic diagram I don't see the camshaft sensor connected going to the fuel pump relay but only gets 12 V from the DME relay but unless the camshaft sensor gives a signal to the DME to let PIN 63 sends a signal going to the PIN 63 of the fuel pump relay. Anyway I'll try to change my camshaft sensor to to see how it does.
