Ok- I just pulled the main fuel pump and tested it on my other car's battery... it's working. Maybe that drive relay then??
I'm not sure what this 'shorting sound' is. IME a short circuit is usually a brief bzzt immediately followed by either a blown fuse (hopefully) or melted wires &/or ruined electrical component (often accompanied by escaping smoke).The "shorting" sound was definitely coming from the pump...
Across the coil? As in from the positive terminal to the negative terminal? If so, that would explain the no voltage reading.Then I checked across the coil during cranking, and it's not getting power either.
That wire, whatever the color, is the RPM signal for the fuel ECU. Easy way to test this is to disconnect the wire at both ends (which means disconnecting the fuel ECU connector). Do a continuity test from the coil end of the wire to pin #1 of the ECU connector....instead of a yellow wire I have a thicker black wire... I will trace it later today.
