Engine not starting

I recent changed half of my engine haven parked the vehicle for 7months. When the new half engine was installed, the vehicle refuses to start but will be cranking. When fuel is forced into the engine (soughing) the engine will start but onnce the fuel forced into the engine finishes, the engine will stop. When the ignition is turn off and the key removed, all the dash board lights will still be on. These dash board lights only goes off when one of the fuses in the banet is removed or the battery terminal removed. The vehicle still would not accelerate after starting my forcing fuel into the engine. The nozzle light refuses to show light when tested with test lamp.

Please, I need help on what to do.
