Does the vehicle not start? I'm curious why you're checking the start fuse for power, tell me what the base symptom is, and I can guide you in the right direction.
OK. My schematic from GM shows a START fuse in your fuse block, but says that it is not used on this car.
What happened just before the car wouldn't start? Did it run normally the last time you shut if off, and now it just won't start? Or did you do some repair or work to the car that caused it to not start? Give me all of the information you can think of so I can help you figure this out.
