Default Re: No Fuel Pump Noise at Start Up

ala_xfire, I took a look back at those harness connectors and noticed the hinge so I was able to pop the top and measure the voltage. When the key is first turned to the on/run position the voltage between the 3rd and 5th pin jumps to 10-11 volts and then drops off. The same is happening at the positive and negative terminals of the pump itself. The battery is reading just under 12 volts on my meter.

The car is still turning over very strongly when I try to crank it but it isn't firing. Also there is still no noise from the fuel pump when at turned to the on/run position. Is it time to order a new pump or is the slight voltage drop relative to the battery a red herring I should look into?
