I have a 1999 Dodge Ram, 114,000 miles, 4x4 extended cab,

A few days ago I went out to start it and it would turn over fine, it
just wouldn't start. No gas was getting to the engine. I realized that
the fuel pump, which is in the gas tank, was not making that "noise"
when I turned the key. This is a fairly new fuel pump, two years old.

I got underneath the truck and wiggled the wires closest to the gas
tank.

The truck then started.

Me not being much of a mechanic and not really wanting to take the
tank off and check the fuel pump, I brought it to a garage. They
couldn't get it to NOT work. They checked all the plugs and
connections and could find nothing, but they also didn't take the tank
off and check the fuel pump connection.

Of course the problem is, if I could just wiggle that wire to make it
work, who's to say another wiggle caused by a bump on the road will
make it not work and cause me to get stranded on the side of the road?

Any thoughts?
