Shut car off, restarted and won’t move forward or reverse, manual transmission.

Hello, if your engine is running but you don't have accelerator response - which is what it sounds like to me - then you could have a throttle system related concern. This will require probably a tow to a local shop to be evaluated. I'm not aware of anything that can be resolved or bypassed in the meantime; when there's no response or the engine does not respond as desired, then it's quite probable that it's in the best long term interest of your engine that there's no such acceleration, or perhaps safety would be compromised.
