Trying to figure out why my fuel pump is not getting any power and determined the power for the pump comes directly off the coil. The voltage leaving the relay panel is ~12V, but coming into the coil is only about 2-3V - that is with the wire disconnected - with it connected to the coil it is only ~.3V. Is this right? How do I determine if the coil is bad? How much for a new one?

The coil is not powered by a relay--it is powered by the ignition switch. The power going to the coil is used to trigger the relay for the power supply to the fuel injection, and that power is one of the two things that triggers the relay that sends power to the fuel pump.
