On my 1990 gmc sierra, I recently installed a new fuel pump, and I jumped the relay to see if the pump would run, and when I did, I jumped the wrong two prongs on the relay connector, and shorted the connector. I spliced a new connector in and now im getting power to the fuel pump, just not the needed 12 volts. Ive talked to a few mechanics and they've said that i've fried a ground. Can someone tell me where the ground would be located? Or is there anything else that could be wrong. Any help is greatly appreciated.
