CAS question.
Hey, I'm working on a 1986 300 ZX turbo and had a question about the CAS sensor.
This car has no injector pulse and I'm pretty sure I've narrowed it down to the ECM being bad and not grounding them. My main reasoning for that is that it's firing the coils but not grounding the injectors and my understanding is that the timing for both of those is the CAS sensor so presumably it should be good.
My question is just confirming that there isn't any other inputs that control ignition or injector timing.
Some history on the car. When it came to the shop it had no power to anything inside, found a blown fusible link (the black one) and don't know why it was blown. There is clear evidence that the customer was either working on it themselves before sending it to us or had it at another shop (fuse panel cover off, battery hold down off, relay cover behind the battery off) so I'm not sure why that link was blown.
I'm also concerned that a shorted injector caused the driver in the ECM to go bad as well as the link. So one way or another I suppose I should probly check them for resistance....
Thanks.
