Pump does not run when key is on. The R/W wire has 11.8 voltage blue wire 11.5; G/Bk 7.5; and Y/B 11.5 Voltage. The G/B wire goes to the Fuel Pump. According to the Service Manuel wiring schematic, the engine coil has the same voltage to it as the fuel pump.
What is the voltage to be on the G/B wire coming out of the "Fuel Pump" Relay? on 1991 Dodge Caravan
