We have already told you what to do to troubleshoot your issue. If the system does not boot disconnect one sensor at a time to determine which line if causing an issue. Once you determine which line it is disconnect the sensor at the quick disconnect connector and plug into another sensors wire and that will tell you if you have an issue with a head or the wire. I am not sure why you are making things more complicated.
