Fuel injectors are not getting fuel

First check fuse seven (ten amp) in the relay center under the hood. Then pick an injector and see if you have twelve volts on the pink wire. They are all fed from one splice and fuse. If no power or low voltage watch the reading and start disconnecting the other injectors. It is possible that you have one or more shorted out and pulling all the voltage down so they do not fire. If you find you do not have power with them all unplugged and the fuse tests good, you will end up tracing the pink wire back through the harness to the relay center to find the problem.
As a test to see if it is the wiring you could run a jumper from one injector pink wire to battery positive. If it now fires up you can trace the voltage loss through that wire. I have seen more than a few vehicles with bad wires under and in the relay centers.
