hi if you turn the key on and the battery and oil light come on bright try to start it if nothing happens but the lights stay bright it is the immobalizer, but if the engine tries to start it is not the immobalizer , then you need to check charge in the battery , make sure battery terminals are tight , all earth terminals are clean , spark plugs are clean ,but first of all make sure the fuse for the fuel pump has not blown it will be in the fuse box inside the car good luck
