I just installed a fresh LS1, and now my tach is not working. The car starts and runs well, but the tach sits right on the needle below 0 RPM and does not move. All other gauges work, except the speedo is pegged to the far right. Oil PSI, fuel, water temp, and voltage are all reading correctly. It should be noted that i completely demolished the #7 piston, could that have damaged the cam sensor? The car runs and starts perfectly. I am thinking it may be a cluster issue, even though I have never had the cluster out or apart. Thanks.

ya the gauges will move a lil just because they are getting power but no serial data signal. happened to me because my serial data wire was cut somehow
