Is the check engine light connected? You can draw codes if the check engine light is connected and if the ecu is showing any errors. If its not connected, the first step would be to connect it. You can connect an led to it for the time being. To find the wire for the cel, you'll need to either open the ecu or find a pinout for it. One of the pins would say 'CEL'.
The issue you're facing seems to point towards the fuel pump or the maf sensor in the aircleaner housing. How much fuel does the tank have? Try putting in more fuel to atleast fill the tank halfway. Its quite possible that the pump is not properly dipped into the fuel due to the position where its installed. The pump itself could be faulty aswell.
