You need to re-connect the 2 wires to the fuel solenoid as they originally were. Also reconnect the ammeter. Replace the blown fuse. You should be able to either hear a slight "click" from the fuel solenoid when you turn the ignition switch to the "on" position.You can also try holding your fuel solenoid with your fingers and may be able to feel the solenoid engage.If you don't hear or feel it engage then turn of fuel supply and remove the solenoid. You will want to catch the fuel that runs out of the bottom of the bowl in a small container(a spray paint cap will work).The reason for catching it is to see if maybe a little water drains from the bowl along with whatever other debris might be in there. After removing the solenoit you can test to see if the plunger is moving when switch is turnned on and off. Sometimes they just get gummed up and you can clean them up and get back to work. If it doesn't work at all then replace it .Just my half-fast opinion !
