Kohler 4.5CKM21 Rv generator Cole 8-24-12  
I need some help getting my generator working. The unit only runs if I connect up a 12v supply to the fuel pump. It seems that something is preventing the fuel pump from working otherwise. The unit is adjusted properly, and has enough oil.
There was what seemed to be the oil pressure sensor on top of the unit, and it seemed to test bad, but I am not sure it is the correct part, or if that is even my problem.
What would cause it to run only when I hook up external power?
Any problems that could cause this issue would be great, the included manual isn't very useful, and I really want to get it working.
Thanks in advance.

While trying to start my generator by using the switch mounted on the generator. As soon as I let go of the switch the generator shuts off. Any idea

My generator starts with start button push on; as soon as I release button the motor will shut off. I can hold the start button for a minute & it will keep running.

what next ?
