Fuel issue. Something else I just thought of. You said you are using a plastic gas container for temporary fuel tank. Is it vented? If it is not and has a sealed fuel line at some point the fuel pump may not be able to pull the fuel from the container (think of pop trying to get out of a quart bottle turned upside down). Also, if you have been starving the old fuel pump, you may have damaged the internal diaphram. Do the fuel system diagnostics were have outlined starting with starvation vs. flooding.
