I don't think codes 4 and 10 would prevent the engine from starting.

Here are some potential causes for your starting problem:

1) Low fuel pressure and flow (pictures 1 and 2).

2) Engine timing way off.

3) A vacuum leak in a hose or connection (picture 3).

4) Problems with the throttle control system (pictures 4 and 5).
