Engine won't start.....

[Cees Donker]

I'm busy with a plane's FM, but the engine won't start. It turnes around, but it stops as if it gets no fuel. What can be wrong?

What aircraft?

It could be the normalized starter torque value in the aircraft.cfg file. Engines must achieve 500 rpm in order for them to start.

Some aircraft have custom gauges that require certain steps be followed, miss a step and they won't start.

stansdds has it correct, and if you do cntrl+shift+F4, then cntrl+F4, then cntrl+enter, it should start.

If not, check fuel, check min. throttle setting in cfg. Add a bit to it to see if it helps, reduce back to zero if not.
min_throttle_limit = 0.01 (= 1% throttle)

Are you at a higher altitude than 3000 feet?

What is your critical altitude set at? Should be at least 3000 feet if normally aspirated gas engine, higher for supercharged.

If turbo prop, ignore all that. :-)

Do you require fuel boost pumps?

Is fuel pressure positive?

Do you have a fuel flow gauge?

If you start in another aircraft with engines running, then switch do the engines continue to run? Is it a start issue or also a running issue?

If you cannot resolve, post or send your aircraft cfg.

Load a fresh flight so batteries are charged. Try again.

'If you start in another aircraft with engines running, then switch do the engines continue to run?' Yes they do! It must be a start problem. I'll take another look tomorrow. Time for bed now....

Thanks for your help gentlemen!

Ceesoes it start and continue to run if you crack the throttle? As noted cfgbadjustment of the starter torque might help, Of more complication is the air file adjustment at low Rpm for internal friction. Keep ,up the good workT

[Cees Donker]

Yes, it works!
