Default Z not starting

At first my Z sounded like it had an exhaust leak. Then my service engine light came on. Lifted it and no leaks. Took it to get the codes read and it came up as a knock sensor. But I changed it about 8 months ago. Although while trying to start it it kept blowing a 15 fuse. It cranks but wont start. When I tried a 20 it still wouldnt start but it didnt blow it either. What the hell is going on? Anyone?

Never (and I can't emphasize this enough) NEVER use an over-rated fuse to troubleshoot. Use an automotive circuit breaker if you need to, but don't go throwing more amps into a wire than it's rated for.

Is the knock sensor OEM or aftermarket? Have you checked the sensor's connector or wires for damage?

Please stop working on your own car. Anyone who puts a larger fuse in place to try to "fix" a short shouldn't be working on any car
