Default 2002 Monte Carlo Ls 3.4L Will Not Crank & PO325 Code.

My 2002 Monte Carlo Ls 3.4L will not crank and the only code its pulling is the PO325 Knock Sensor 1 Circuit (Bank 1 Or Single Sensor) - PowerTrain.
Wonder since these models only have one if itd prevent it from cranking at all? It trys to turn but it won't but everything is working and security light flash's, So Im pretty sure it's in fail safe mode.

I'll get into more details in awhile how it started, Been busy the last few dayfew. Thank you for any help.
