Assuming so, I would pull the pump out and ck the two wire continuities down from the connector to the pump itself using a VOM. Suspect maybe one, or both, of the connections/connectors might be faulty. You had to splice in connectors when you installed, yes?
DO NOT ATTEMPT TO RUN THE PUMP WHILE IT'S OUT OF THE TANK!!
Why? Two reasons:
- It's a fire hazard! These pumps are designed to be operated when submerged in fuel; i.e. sans any oxygen. When out of the tank it will have residual fuel in the pump and plenty of air around it. These are DC motors so the commutator can and will spark.
- Bad for the pump; the fuel going through it actually lubricates it and keeps it from over-heating.

You might want to try a new fuel pump relay. There is a way to jump the relay in the box but I don't the the terminal numbers off the top of my head. If you jump the relay and you hear the pump then you know it's the relay that's faulty.

Using a paper clip to jump between the socket positions associated with pins 15 and 87 on the relay is the procedure to by pass the relay itself. If the car runs OK the relay was bad, if you still have no fuel pressure then the fuel pump itself is likely bad.

Newest update
I pulled the fuel pump to change it out and when I was removing it from the upper housing the red wire dropped off the solder connection where it joins to the external wires. This was on the inside connection so it was not visible until the pump was out and then it looked connected until I moved the wire and found it not connected.
I resoldered the connections and put it all back together and the car started right up.
