I have a 2007 s40 t5 awd that had a faulty fun was replaced and manual pegging was done on the injectors after which it sparked but rpm was high engine was shut and now the car won't start again but cranks after which a mec came tried to spark from battery starter now it wouldn't even crank again just a shilling sound with immobilizer see manuals in dash any help

 

there's a procedure for resetting the immobilizer - try googling the topic and you should find some posts. Its something along the lines of locking/unlocking the doors with the key fob 5 times or so to get the computer to sync up.
