Hey everybody, I've got a 99 kee that i'm having a issue with. I have looked everywhere for a wiring diagram for it, my distribution center under the hood is not right. I have power to everything except to fuses 21( pcm, ignition) and 24. I could use any help I can get.

The ASD (automatic shutdown relay) controls power to both those fuses.

You can swap the cooling fan relay with the ASD to test the relay.

I tried that earlier but still couldn't get power to them. I was trying to find a diagram to track the power stream. Thanks for the ASD tip, another question, would that keep it from starting?

Here is what the ECM does.

Pull the ASD relay. Pin 2 should be hot (12 volts) all times through fuse 19. Pin 4 should be hot (12 volts) with key on through fuse 11.

The ECM controls the ASD. It sends the signal to close the relay and power the ASD which powers the fuel pump.
