With compression that low, you won't get anywhere near an adequate combustion cycle. Check your timing belt to make sure it's set correctly. If all of the marks line up and the belt isn't stripped anywhere, I think the next step is taking the head off and inspecting the pistons and bores etc.

(I disconnected spark plugs on 2 and 3 while it was running and no difference was made telling me that they for sure aren't firing). I put some oil in they cylinders and rechecked compression and it didn't make any difference, so would that rule rings out? Where should I start from here. Thanks again.
