So I believe the fuel pump went out in my Jimmy. I replaced the fuel pump relay on the driver's firewall. Still don't hear it come on. I also read in a manual that there's a fuel pump test connector down near the pedals between the fuse box and the diagnostic connector.

So I pulled the panel off down there near the pedals and found two wires going into a plug that was unplugged. I found the other half of the plug (also obviously unplugged) which only had one wire in it. Looks like one side has a black wire and a purple wire with a white tracer. The other side just has the black wire, no purple wire. They say something like 32 PED and 20 PED with an A and a B for the wires.

Anyone know what this is for?
