No working liquid fuel engines

[Furifix]

I am on the newest version of ksp and don't use any mods. no engine, except for the small ones with integrated fuel tanks, is working. Does anyone know what to do when they work? It will help me very much. Thanks for your awnsers.

Do you have fuel tanks on the craft? Are there parts between the engine and the tank? 

Also, welcome to the forum.

And I'd like to add this - have you tapped the spacebar? That's sorta the "launch" button...   (and staging button, too.)

If you can share a picture of your craft in the VAB, that might help us diagnose it, @Furifix.

And welcome to the forum...

[Furifix]

Thank you both and yes i took fuel tanks and hit the space bar.

And it is with every single spacecraft. I tryed to fix this bug for 1 month now.

Have you hit z to throttle up?

Did you make sure the tanks you added contain both liquid fuel and oxidizer?

If you tried a jet engine, did you make sure you added air intakes as well?

[Vanamonde]

Some parts will block fuel flow. What's between the tank and the engines? 

[Furifix]

I tryed with and without things in the middle. I tryed the fuel pilotages too.

[Furifix]

So ghere arent things between the tanks and the engines

 

[Furifix]

They also sound like there on and it says that they are on but there is no thrust.

And yes I tryed air intakes @Lt_Duckweed

Really a picture would be nice. In the editor or on the pad with engines on. F1 for ingame screenshot, saves in game directory, (or default F12 for steam), upload somewhere (imgur.com), post a link

[Furifix]

Ok, ill do that. What do you exactly want? Only a picture of the space craft?

[The Aziz]

Pretty much. Guess we'll figure it out from there (or ask for more if needed)

But i can build anything and nothing works

Hi, welcome to the forums.  Two questions.  Where are the wheels?  Do you see the exhaust plume come out of the engine when at full throttle?

[Vanamonde]

Why don't you try making a test ship that's just a capsule, fuel tank, and engine, and see if that works? No need to fly it anywhere. Just see if the engine fires. 

[Furifix]

It doesn't work. Only boosters work.

I think the problem you’re having is that you haven’t throttled the engines up and so they (correctly) produce no thrust.

1. Build this in the VAB: Mk1 pod > FL-T200 fuel tank > Swivel engine. Make sure there’s a Kerbal in the pod, by default Jeb should be in there.
2. Click launch to get it out on the launchpad.
3. Throttle up to full power with Z or by holding shift until the throttle reaches 100%.
4. Stage with space.
5. Take a screenshot and post it here.

The rocket should go up extremely fast; if it doesn’t then something is wrong with your install and you should try uninstalling and reinstalling the game.

Solid fuel engines don’t need to be throttled up and once ignited will burn until their fuel runs out, but liquid fuel engines (both rockets and jets) are throttle-controlled and won’t produce any thrust unless you increase the throttle.

Thanks!!!! It works
