my comp is very low and i was told it was valve/cam timing but everything was right before start up

yes ive done a compression test it show inbetween 350 and 400psi on all 4 cylinders and there is spark and the ground is all there and its a oem cambelt and about the 180deg sensor turn im lost as i dont know what it is....i was told by two mechanics that my valve are staying open and its not seating and the one also insist it was my gear as it jumps 3teeth is it possible? im really lost?

good day peep im having problems starting my redtop beams i have taken the head away to engineering as my cotter jumped out got it back everything was perfect assembled everything put my timing on tdc every was on tap and i wanted to start it swing like there was no compression..i was told it was cam or valve timing when i disassembled the motor i mistakenly took the vvti gear apart but go it back together...can my vvti gear/pully cause my car not to start as its jumping timing please help!!!!!
