2003 Park Avenue fuel pump circuit schematic
Hello!
Would anyone out there have an '03 factory manual they could snap a picture of and send? The ones I've found on the net are unmarked as to the year and source, and don't match what I have in the car.
It'* a long story...
Thanks in advance!

Wire #85 (relay coil to ground) had no wire in plug cavity. How was the coil to be grounded if there was no wire? Beats me.
I plugged the relay in and everything works as should. My question still is, how is the relay coil grounded without any wire going to ground?
All the schematics I found show a ground wire.
Thanks

Someone had added a wire from the ground pin on the relay itself to the chassis ground. That'* when I started looking for a wire that could have worked its way out of the male plug. There was no loose wire, and the cavity in the plug for the ground wire was empty. I plugged in a new relay, removed the added wire, and the car fired right up and so far the fuel pump is working. On to bigger and better things!
