anyways everything seems to be working fine expect the injectors, they stay open all the time, im using the stock harness with resister box

any help or experience will be helpful thanks

 

What troubleshooting have you done in order to try to figure it out?

Most often this is:

1) Miswired injectors
2) Short in the wires going to injectors
3) Damaged transistors that control the injectors.
