Fuel pumps make a whine as they run, it is loud enough to hear with the engine off, while sitting in the car. If it dosn't run check not only if it is getting +12 volts but that the ground is good. If it runs use a fuel pressure gauge and make sure the fuel injector rail is getting 28-30 psi. Also make sure the battery is good.

What is a "FIB"?

Could it be "Fuel Injection Brain"?
