my wild guess is you defeated the IC17
with a hot wire jump
now when the car (or any wire or related sensor) shorts
you blow crash the CPU (Microcontroller) and and all spark and all injections end, (or worse damage to Q105)
that is the purpose of IC17 to prevent all that.
as you can see sensor analog power is not the same as digital 5vdc logic. and is separate for very good reasons, for sure on any car.
"what I'd have done. is use 5vdc LDO chip regulator and mount it inside to 12vdc and ground and output to pin B6"
then it works with no loss of digital power ever.
