These are only symptoms could this cause the ECM fuse to keep blowing and.no crank also scan tool could not connect to ECM.

It sounds like you have an electrical issue. Check the DTC connector to make sure you are getting power and ground. A short to ground could be the cause of this concern. It may be possible that the reverse safety switch has a pinched wire somewhere. Try unplugging the sensor to see if the fuse continues to blow. Electrical issues are tricky to figure out sometimes. If you need help with this, I suggest having a certified technician, like one from YourMechanic, determine the exact cause of your electrical issues.
