If I have already read a bomb and I get the pin

I have two pins for the car and the one for the new pump, which it refers to

once programmed it keeps coming out the same pin of the pump

Don't forget to program vin as well pump is programming incorrectly and not keeping pin
All I can suggest is reset all units then reprogram I'll try make you a complete guide.
Aslong as you reset pump with the pin it came with and then using the pin that matches all other units when programming should be correct.
The only thing is if its incorrectly synced it won't work hence why I suggest full reset

Go on immo then measuring blocks and check the blocks for key post screen here also scan all units and screenshot any faults here.
