2013 Kia optima with 2.4l. won’t turn on. Won’t even crank for the most part. Clicks like it’s a bad starter. Starter has been replaced. Alternator is good. Battery is good. All fuses and relays have been checked. All grounds seem good. If I hook a booster up to battery and give it 14volts I can get a very slow and small crank out of it but stops right away. Has a code for camshaft position sensor but had that when it was running and I’ve never heard of that causing a no crank.

I fear that maybe the motor is locked up but I’m far from a mechanic. I’m gonna see if I can move the crank pulley bolt later but was checking if anybody had any ideas of what to check or what my problem might be.

Thank u
