Just bought this truck. Ran good. Alternator went out 10 miles down road. Put new alternator in it. Jumped off and it ran great home. Even crunk back up. Came out in morning to it being completely drained. Put 2 new batteries in it crunk right up. Then again completely dead next morning. Jumped it off. Drove to the shop to do parasitic draw test and check with multi-meter. After testing fuses wouldn’t start at all. Tries cranking but acting like it’s not getting fuel. Driver window went down as soon as we put key in and will not roll back up. All other windows and locks have power. We’ve primed fuel system ect. Lb7,fass fuel system. Efi live tuning on 5 position knob. Picks up a big power draw when hooking jumper cables or even hooking terminals back up to battery. No start at all. We’re stuck. All fuses and relays appear good. Any help would be appreciated drove good to the shop ones jumping off.
