97 Chevy k1500 ignition problem

Ok so I’ve just replace the ignition switch and lock cylinder but I can’t seem to find what’s causing the problem , every time I go to start my truck I’ll turn the key to RUN/ON and it’ll try cranking it’s self on it’s own without me even trying to crank it and the starter will stay engaged until I kill it by turning the key to off any help ?
