2003 Dodge Ram No fuel Pressure

I checked the voltage to the wires on the fuel pump. I found that there is a blue/white wire that has 11.37 volts. And the green/white wire only has.37 volts. I'm not sure what the blue/white wire is for (fuel sensor maybe). And before checking the voltage I checked to see if I could hear the fuel pump when the key is turned to the on position. I heard nothing. I'm thinking I may need to jump the green/white wire?

I ran an cable from the green/white wire to the fuel relay. It started right up! Is there a reason or way to fix the problem now that I know its just not getting power?

I have the same problem the truck would just turn off running and would not turn bac on for hours I also bought the gas pump, crank and cam positioning sensors and the diagnostic computer was reading clogged catalytic converter or vacume leak, my truck is a 2003 with 74k mles. In my case apparently it something loose in the fuse box. I just dicovered this a few minutes ago it started to rain while I was working on the truck and the wipers wouldnt start nor the truck would turn on but it would crank. I accidentaly tapped the fuse box and the wipers came back on and I tried to turn on the truck and it turned on instantly. Now I noticed thatt if the wipers dont work the fuel pump wont work either. Im not saying that the wipers have to be on for the pump to work but when I see that the wipper stops working so will the pump. Im going to look around the fuse box and see if I see something loose.
