Run a wire. Straight from the battery to your fuel pump.
You should use an inline fuse too just in case.
You don't want to short something out.
With the fuel pump running try starting up the car.
Does the engine run fine now?
If it does then you must have a short somewhere in the wire to your fuel pump. Loose Connector , backed out terminal, bad connector, or a bad wire.
no fuel
