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?

Your wiring has been hacked on, as the fuel pump power normally comes off a dedicated relay on the relay board. Is this a carb'd car?
The coil shouldn't affect power unless the wiring was done very oddly. The fuel pump power wire should connect to the same post on the coil as the coil + power. Where are you measuring voltage? What's your ground? |
