Cajun, if you know as much as you think you would know that there are two types of wiring used on fuel solenoids. Single wire which uses the solenoid body as the ground and two wire, with one wire being used as a ground. If you have a two wire circuit and you connect those two wires together, you now have a dead short to ground. Simplest way to test a fuel solenoid is place one hand on the solenoid and turn the key to the run position. If you feel and hear the solenoid engage it is working. If not, you second test is to take a test light and check for power to the solenoid. No power, electrical problem before the solenoid. Power, bad solenoid. Can’t be much simpler, even for a DIY guy.
