Well the kids car quit running yesterday afternoon. My thinking was the fuse had popped out. NOPE. Then the fuel pump had died. Can't tell.
I don't have 12volts at the pump. Not even for 1.5 seconds.
Using Brad's trouble shooting flow charts.

Using the Isolate flow chart. I get to the bottom right corner. It asks to connect the DMM to PIN III on the small white ground harness at the back left corner. Is he asking that the connector be in the board socket or in my hand ?
Either way I never get a ground signal.
Should I have 12 volts at the pump all the time ? Or does that 1.5 seconds of ground just open the relay. Somewhere in Elec 101 that didn't sink in. I don't know how to read the relay switch diagram.
Next should I be able to bench test the 3 fuel pumps I have ?
