Depends what the short is.
Ground to ground: no
Positive to positive: no
Ground to positive: yes.
The computer switches ground to open and close the injectors. Being a batch fire system with all firing at the same time you wont have running issues with same current shorts like you would if it was sequential.
If there is a short between opposite currents it can overload the drivers and cause them to fail due to a drop in resistance and increase in current.
The high impedence LH drivers are much more delicate than the low impedence L jet drivers.
