The manual has a section on troubleshooting - for your convenience, I'll copy it here;
The Shuttle doesn’t hold a clean trajectory and crashes after liftoffIf you intend to fly autopilot, check that
* the launch guidance dialog has a valid target and reads ’active’
* the PITCH an YAW/ROLL pushbuttons on panel F2 are on AUTO
* throttle pushbutton is on AUTO
If you’re trying to fly manually, check that
* the PITCH an YAW/ROLL pushbuttons on panel F2 are on CSS
* throttle pushbutton is on MAN
* your control device is properly configured and centered upon liftoff
* auto-coordination is off
For instance, non-centered pedals sending a rudder signal upon liftoff can kill you.

Autopilot steers the Shuttle westward and fails to reach orbitWhen starting up FG, you did not pass a --heading option to orient the launch stack properly. As a result, the tail fin of the Shuttle points westward, and pulling back after liftoff leads to the wrong launch azimuth. There is usually not enough performance to reach a retrograde orbit, so you will end up on a ballistic trajectory back into the atmosphere.

Make sure to start FG with the proper orientation for the launch pad by passing a heading parameter westward -
this will point the tail fin eastward

also, some also, some times is going to move before I started up. Also is on horizontal direction
Do you mean the launch stack is toppled on the pad and not standing upright? That's a bug which for weird reasons occurs on some computers but not others, and it /should/ be fixed in the devel version (which hopefully gets synched with FGAddon soon).
