Well I can see I hooked the splice up to the wrong wire on the HP pump... oops! That's likely why I have power to the in tank pump coming thru the tank selector switch.
I'll fix that Thursday night if I get home at a reasonable hour.

Not sure what you did, hard to tell from the photo angles.
if you jump the Inirtia Brown wire with the Pinkwire at the HP pump connector, and you have a proven ground,then your HP pump motor is bad.
if you jump the Inertia Brown with the Pink wire at the HP pump connector, one of the tank pumps will come on depending on switch selection. This is a good sign that the Pink wire is ok.
nice jumper on the test connector by the way...

looks like I jumped the brown wire at the inertia switch to the brown wire at the pump. Should have jumped to the pink at the pump to power up the pump.
That first fuzzy photo is the HP pump and connector.
BTW.... never waste your money on Chinese knock off Scotch Locks at O'Reillys.... junk.

Are your wire colors different than the drawing?
Brown wire at the pump? The wire that leads to the rear in-tank pump ? Brown/White stripe?
If the in-tank pump was running (but wasn't before), then you had power on the pump power wire.

The pk/bk wire is hot at the inertia switch but not at the pump.
The yellow jumper was supposed to power up the HP pump but did not... I do have noise at the in tank pumps....at least one of them (the rear I believe). I put three gallons of gas in the rear tank and five in the front.

Upon further review I did have my jumper wire hooked to the pink/black wire that powers up the HP pump. I have power in and out of the inertia switch but nothing to the pump... I would think I'd still have power at the pump while checking with a test light but I do not.

If you jumped from the inertia to the pump, you should have power to the connector at the pump.... if the pump is grounded properly it should run, if not the pump motor may be shot...
Does the in-tank pump run without the yellow jumper connected?
Have you proven a ground connection?

" power at the pump" what do you mean by this, at the connector to the pump? the wire to the pump?

I checked the yellow wire that runs from the solenoid to the FP relay... hot on both ends. Power in and out of the FP relay to the inertia switch...
When the wrong pump comes from Rock Auto (again) I can then order the correct one and start over with a new HP pump.
One a brighter note I got my shop air compressor repaired by replacing the start and run capacitor's on the motor.... a good $25.00 repair!!! Not having air for two weeks is pretty challenging...

Didn't you tap into the Pink wire at the pump with your yellow wire?
suggest you do this as close to the pump as you can get...
post a photo of the wires coming out of your pump and the pump....

So, where are you checking for power at the pump?
you have power on the yellow wire right?

disconnect that connector;
measure the resistance on the black wire to the frame. (red lead to the black wire, black lead on the frame somewhere)
(the black wire leading back to harness side of the connector, not the black wire to the pump)
note the reading.
Measure the pink wire inside the connector that leads to connector side that the yellow wire is tapped into, (not the pump side)
note the reading.
