My 93 Non Turbo manual 300zx, the car won’t start.. We replaced the crank angle sensor with another used one. And bench tested the PTU. When the problem first started, it just wouldn’t get a spark. We first replaced the crank angle sensor. After checking everything else I replaced the CPU with a used one. After doing that the car would start for one to two seconds. We checked the fuel pressure after the pressure regulator and it is good. At this point, I’m wondering if I still have a bad CPU. And was wondering if anyone knew how to bypass the CPU to allow it to run or if anyone has had this issue.
