just for the heck of it...look at the top of your pump.  Next to the connectors, there should be a couple of metal contacts.  I think they are test points or maybe just the attachment rivets for the terminals.  touch power and ground wires to those points next to the appropriate +/- terminals.  See if the pump then works

Steve... Do you recommend I replace the in tank wiring?  This Walbro came with the wire that plugs into the pump and goes to the hangar.

I would....these harnesses are really old and the ground side has always been weak

Racetronix sells an hd harnesses that replaces the bulkhead connector in the sending unit and runs the ground wire all the way to the connector so you have a direct ground path.  Be sure you tug gently on the wires to make sure they were well crimped in the bulkhead connector

I just ordered the one you described. 
I'll test the pump as you described and report back later tonight.

I went for the complete new hangar, harness, and hot wire kit from Racetronix - I love the build quality and value.

thought mine was great until I redropped the tank and soldered the wire that was not crimped on both sides...did not bother to contact them because they build perfect stuff

Glad I did not pour a lot of gas back in the tank before I tried it after install

Update:
 
I put the Walbro pump on the bench and hit it with 12 volts.  It made a sick sounding humming noise.  I then hit the two points that Steve mentioned and it made a similiar humm noise.
 
I then hit the stock pump with 12 volts and it sounded like it was ready to take off.  Sounded like a normal pump should.
 
Looks like the Walbro died a premature death, then caused the fuse in the Hotwire harness to blow.
 
Looking on the bright side of things, at least it $hit the bed in my driveway  :cheers:

yeah, when you said it blew the fuse, I figured it had died but someone recently showed one that would run when you went to those two points so i was curious. :icon_smile:

Absolutely!

The product is great...just the execution of assembly was bad in my case...but

I will check it the next time instead of trusting

I had a similar experience.  I don't blame Jack at Racetronix, but there was a QC issue when they shipped out my dual fan harness with 30 amp relays and 20 amp fuses; thus causing the fuses to pop the instant the fans came on.  Jack said he had a bunch go out the door with the issue.  Good thing Racetronix had included spares in the kit.

Here we go again...
 
Update:  I replaced the dead pump with a new one, and also installed the intermediate wiring harness... voltage to the new pump made it sound like a healthy pump should. 
Installed averything in the car, put another 5 gallons of fuel in the tank, turn the key and no start...  The pump runs when I first turn the key on then stops like it should.
I disconnected the hotwire and tried it with the factory wiring, and still no start.
I do not have fuel pressure at the rail.
I plugged my jumper wire from the fuel pump test lead to the hot stud on the alternator and the fuel pump will run, but no fuel to the rail.
Checked all the pertinent fuses and nothing cooked.
WTF   :013:
 
Willing to pay a reasonable rate for someone to come to Harrisburg, PA and diagnose the problem! No kidding.

disconnect the rubber hose that goes from the tank steel  tubing to the steel fuel line that goes to the front of the car

jump the pump and see if fuel spurts out as it should if the pump is working
