I have 2006 Ford F250 Turbo diesel and the battery light, the TBC Fault light, the engine light and a wrench light came on. Truck just clicks will not start. I replaced both batteries less than 2 mon

...perhaps when the fuel injector module was replaced...a critical connector got unplugged...sounds like...on my side of the street~

Have it scanned and see why the wrench light is on. That is where the problem will lie. As far as the clicking goes sounds like dead battey. Battery light on sounds like the alternator has stopped charging. Start with the light and post code(s) on here.
