Jet engines will not throttle up

[tarkus54]

For some reason my jet engines will not throttle up. The throttle will go up until the engine is activated and then it drops to zero and will not move. The idle engine sound comes on but that's it. All other rocket  and propeller engines work fine.    And Yes I have intakes. I've even tried it with stock craft.

Does anyone have any idea what might be causing this? Has anyone else experienced this?

Another thing which is happening is - I build a space craft and it works fine. The next time I load the game it says parts are unavailable.

Do you have air intakes on your craft?

Jet engines will always need at least one air intake on your craft, depending on your number of engines and desired flight altitude, you'll need more than one.
