Wwat would cause the fuelinjectors to stay on w/no brake when the key is on and not cranked or started? It will fill the intake (andcrankcace) with fuel.

. Check for codes.

. Focus on the ECM and main relay. It's possible there's a problem with the ECM. Try resetting the ECM by removing the Backup Fuse for 10 seconds or disconnecting the negative battery cable for 10 seconds. Keep a fire extinguisher handy and do all work outdoors. No sparks.
