OK, jumping did nothing. Relay is good. Put a new one in just to see.
I am getting 11.5 volts when I measure voltage on the pink/black (hot) and black wires (ground) on the pump connector.
Did a test:
- I took an old pump and held a wire to the red and black terminals and hooked it up to a battery, the pump fired up.
- Hooked up the verified pump to the pump connector on the truck, turned the key and nothing - the pump did not run.
- I even measured voltage on the red and black wires on the sending unit. Nothing there
So I am not understanding how this pump works. There are four pins on the connector. One is power, onen is ground (both of those work). So the other wires must have something to do with letting that power into the pump unit (and whatever that connection is, that should be the problem). Those two wires must also have something to do with shutting off the pump after 2 seconds, right? The diagram says the orange goes to the same ground as the black wire, but what does the Y/W do? Whatever is wrong with those two wires, is stopping the voltage from going through the pins on the pump hanger and into the wires connected to those pins.
Please be patient with this thick headed man.
