Im new to the TBI conversions and i have an 83 firebird im putting a TBI on and i followed the pinouts provided and im not sure if i may have missed something, no pulse from the injectors on startup, im not using the 4l60 and im wondering if i need to find a non automatic harness? i have not connected to coil to the distributor but thats about all that is left to add, is that my issue? thanks, nick.
