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?

It is working, but who know for how long? I took an external 12V source and hooked it up to the fuel pump to make sure it was in facet the fuel pump. The car started right up! So at least I know it is the fuel pump. Reconnect the wires and try it again just for grins - and it runs fine?? WTH?? Any ideas? Is it a fluke, and when I get more than ten miles from my house is it going to strand me again?

I can tell what kind of car this is going to be!!
