fuel pump not getting power...any ideas....?
Lets get a little history of whats going on with my car right now......
I just finished with a rebuild and just completed putting the motor back in the car...
Everything seems to be ok as far as all connections and wiring in the engine bay. I have used the Helms manual throughout the process so I'm sure everything is correct.
When I turn the key to the "On" position I should hear the sound of the fuel pump humming (in a perfect world) which I dont. I took the multimeter out and tried testing the fuel pump for voltage, which read 0.0. Next I tested the fuel tank high/low gauge for voltage and I got a full 12 volts. It sounds like the pump is bad to me however I do not want to say that until I can get power back to the pump. From here I tested just about everything my Helms guide said to: wires, fuses, etc.
When you first turn the key to the On position I think you should hear a/the fuel pump relay(?) click on then click off a couple seconds later, but mine clicks on and off rapidly and sometimes makes a strange buzzing sound randomly. I am out of ideas when I got here.
Does anyone have any ideas or know of something I may have done wrong?
Thanks in advance.

if you don't here the fuel pump priming, and you already replaced the pgmfi main relay, look in the helms , find the pin out for your wire connector at the fuel pump, its under the back seat,
take a a 12v lead from your bat, and a grnd, or just use a batery charger if you have one, and apply 12v directly to the terminals of the fuel pump, if the pump runs or not will tell a world of a story,
try that and post back

wat i would do, is look for ground, and look for voltage at the pump...if you get both the pump is bad....i wouldnt even bother trying to get power sources theres....just take a test light and check for power and ground while one of your homies cranks the car.
