Had a friends truck today cut off on him and when he hooked it up to a code reader it said<br />
<br />
. Fuel injector group "B" supply voltage circuit open. <br />
<br />
What could this mean

Im not at all a code reader, however, it sounds like it has to do with the second group of injector wires (the ones closest to the firewall 4,5,6). If you look on the right side of the valve cover (if your facing the truck), there are 2 different plugs with 6 or so wires in each. One plug is about where your intake manifold is, and the other is about halfway back on the fuel rail. When your reader said "injector group B", I would assume its referring to the 2nd plug. Just thinking out loud here. Maybe check it out and see if one of ther wires are cracked or broken.
