When you turn the key to the on position the PCM relay will send power to the fuel pump relay. Fuse 13 is the fuel pump fuse itself on the switch side. The PCM ground is a light blue and orange wire. I would first replace the PCM power relay as they are known to fail over time to make sure this isn't your concern. If the vehicle runs when the fuel pump is jumped you can ground the light blue and orange wire. The only issue is it will run anytime the key is in the on position. Hopefully this information helps.
