First things you need is, fuel and spark. Be sure you really have gas and it is getting to the engine. No fuel work backwards towards the pump check the lines, filter, and pump it self. Repair as needed to get fuel. Electric fuel pump you need to listen for whinning sound fo the pump running when the key is turned to on. Also check fueses and pump relay. If the fuel part is ok check for spark to the plugs, coil you get these 2 things the car should run but may not be running well. many other things would need to be checked after it starts.
