truck was riding rough, took in to hook up computer today. It read that #2 and #4 misfiring And bad cam sensor. I replaced all spark plugs and put new cam sensor. Started the truck and was running smooth. Check engine light was still on. Didn’t know if haven’t had enough time to reset yet. I left work to go to Autozone so I could put back on the computer, to clear the codes. Then truck started clacking really loud. Light came on saying check gauges, they died. Hasn’t started since. Gauges read ok when turn truck to on position. Henceforth I walked to Autozone for a computer got new codes P0018, P0022, P0340, P0345, P0349. It cleared the misfires so I atleast changed the plugs right! I tried to put the old cam senor back in to see if the new one I bought might have been bad or defective, but same out come. With whatever happened so fast and shut and locked whole system down. Has me at a lose. when try to start it, no crack and just a thud. All needles on dash bounce vibrating until turn key off.
Im lost, anyone else have this problem before?
all input will help.

Regrettably, the symptoms (and corresponding codes) sounds like a catastrophic timing failure. - Total failure of bank 2 phaser, like clock spring, or worse - jumped timing on chain and perhaps got valves since it won't start at all. That P0018 is not a good sign.
