Engine light on after timing belt attempt

[joemendez217]

so i purchased all the parts to give my single jingle and nice tune up till i save for this b20 using the gas money i save with 38 mpg lo .. but i have failed TWICE miserably ive been under my car for a total of 16 hours and ive done n oil change new gasket seal new dizzy and spark plugs 3 hours worth of work but i found everything that is wrong with the car from horrible tie rod boots got new axles and shift links too so i wanted to change my timing belt and i figured a water pump too while im in there so im all the way down to finally the the pulley bolt and after trying 3 different air guns on a 35 gallon 155 psi tank no luck two break bars still nothing gave up slapped everything on untuned... a day later my engine light comes on get codes p0335 and 0336 and i think i know they said it was my cam censor could that be from us attempting to get the bolt off cause this or could it have finally just gone cant change it because i cant get the timing belt off to get to it... ruff week any tips ideas with the codes and or tune up help with this timing belt or bolt
