No power to coil

I have a 95 Silverado Z71 with a 5.7L. No power to Ecm1, Engine1 fuses under the hood or coil. Battery is good had it tested. Checked pink wire coming out of ignition switch and it had power but there is no power going to coil. truck will turn over but will not start up any help would be greatly appreciated .

the pink wire goes from the ignition switch to two circuits in the underhood fuse box and the ignition coil. One circuit goes to ENG-1, ECM-1, IGN-E. The other circuit goes to GAUGES, FUSE 4, AIRBAG FUSE 10 and TURN/BU FUSE 16.

If all those fuses do not have power when the ignition switch is turned to start or run check the pink wire as it comes from the firewall connection. If you don't have power on the hood side, there may be a bad connection between the two halves of the connector.

If you do have power on the pink wire on the hood side of the firewall then you may have to check it between the coil to the firewall connector and underneath the underhood fuse box.

I would use a tone tracer on the pink wire while the ignition switch is in the off position. (turning the switch off makes the wire only go in one direction, to the engine compartment) The tool sends a tone signal through the wire (in this case it would be hooked up to the pink wire) and has a receiver that lets you follow the tone in the wire without having to open the wire harness. You can just follow the wire harness and hear the tone signal. if there is a break in the wire or the connection is terminated somewhere in the circuit the tone will stop. Makes it a lot easier to trace a wire.

Check high tension coil wire for short where it lays against transmission dip tube after it leaves coil.
