Low compression, all Cylinders...how do I replace timing chain? on 2007 Pontiac G6

I have a '07 G6 GTP, I have spark, and I have gas...my thought is it should go boom...tried ether and still nothing. It will crank but thats it. I used a compression tester and only have 30 lbs of pressure on each cylinder which i believe is supposed to be like 125 lbs. I am most certain it isn't a bent valve so my only other thought is timing. Can anyone tell me if it is computer controlled or is there a belt or chain and how to fix this? Thanks

IF timing is off , then most likely you have bent valves, silly , but serious question , if you're not sure if it's chain or belt how can you verify correct timing?

Go REALLY early, and stay REALLY late. Sometimes the bands that play first come out in the lobby area or near the merch table.http://www.lightdeal.co.uk/
