After running out of gas, the system is still full of air/vapor. In the fuel injection system, the pump will run momentarily each time the ignition is turned on. You should be able to hear the pump. Each time the pump runs it purges some of the air through the return line back to the tank. Try turning the ignition on and off about 10 - 20 times to purge the air and vapor and fill the system back full of gas.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

    I suggest you might pick up a can of starting fluid. Carefully follow the instructions on the can for cold weather starting, and observe the warnings for it's use. If you really have a fuel related problem you should at least get the engine to respond. If you were really low on fuel it may have picked up some water from the tank. If you get the engine to start using the starting fluid, the water should pass through and the engine return to normal operation. If the engine does not respond to the starting fluid, there must be some other problem, such as ignition or a mechanical problem. Meaning that you didn't really run all the way out of gas to start with. In which case repairs are necessary.

Why is gas shooting out of gas cap?

you have 2 options
1--- put the fuel return line into the tank you are using
2--- install a balance line between tank 1 and tank 2 so that the fuel back to tank1 is allowed to balance back into tank 2

properly set up the tanks should be connected so that the fuel gauge reads the total fuel in the tanks and there is a need for only one fuel pump

Not pumping fuel will not start,only rear tank was working untill ran out of fuel put in gas will not start ?

If there is power to the fuel pump, check the fuel pressure. If power and no pressure, then pump is bad. Water in the tanks will kill the pumps fast.
