Hi,
You get your problem sorted?

First you need to bleed the fuel system.
Second if you have disconnected the battery you need to reinitialize the BSI.
The key codes are not lost, they get lost if someone reset the BSI unit by mistake or using a wrong diagnostic software and corrupt the BSI unit.
if you need more information let me know.

Hi Mark,

1. Whenever a vehicle battery has to be disconnected, switch off all equipment interior lights etc. close the doors
leaving the driver's window down.
2. Switch off the ignition and remove the key and DIAG if connected.
3. Wait a full 3-minutes before disconnecting the battery.
The BSI must be allowed to go to sleep i.e into 'Power Save' mode. Do not operate any equipment on the vehicle during
this time. Remember, even opening the bonnet will wake up the BSI on the vehicle fitted with an alarm.

1. Close all doors on the vehicle, leave the driver windows open, leave the bonnet open to have access for battery
2. Remove the ignition key if left in the ignition.
3. Reconnect the battery.
4. Wait 10 seconds.
5. Switch on the headlights through the driver's window. You will hear a 'Bong'.
6. Switch on the ignition then start the vehicle and check systems are functioning.
Upon reconnection of the battery: If any vehicle function controlled by the BSI i.e. interior light is switched on, the internal operation of the BSI has the potential to spike or corrupt its configuration and software program.

you can swap them but that is not mean the engine not start, the code is only for the ECU to know the "class type of injectors" if they are not codded correct in ECU you can have a bad runner engine , lot of fuel consumption lot of smoke bad rev on idle etc.
