May 12, 20224 yr I've filed a support ticket with FlyingIron but haven't had any response, so hoping somebody here may be able to help: From loading a flight cold and dark, I'm using the engine start checklist on the tablet and starting from cold and dark works fine with v1.1.0. But using the same checklist with v1.2.0 (and not doing anything different from v1.1.0) the engine does not start. I have tried numerous times and I am absolutely sure I am following the checklist correctly. The low fuel pressure light comes on when I switch the battery on but it goes off as soon as I turn the fuel on, without using the wobble pump (so something seems to be wrong there). As I understand it, this light should stay on until I've boosted the pressure with the wobble pump (as it does with v1.1.0). I give the wobble pump 15 strokes anyway and prime 5 strokes. With the mags on and pressing the boost coil and engine start buttons, the engine turns over but only with a constant low volume whirring sound and without the sound of the piston compressions turning over that I hear in v1.1.0 (so again something seems to be wrong there). It does start using CTRL + E but still without the initial piston compression sounds that I hear in v1.1.0. I know I am using the correct switches, levers, buttons, etc. because what I am doing works correctly with v1.1.0. I've followed your "Why won't my engine start?" guide in your FAQs. I've made sure there is fuel in the tanks. I've tried with and without using the wobble pump, with and without priming, also with additional priming (13 strokes). (OAT 14 degrees C.) I've tried using the booster coil and starter buttons one after the other and I can see them both depressed together. I've tried using the clickspot between the booster coil button and the starter button and I can see them both depressed together. I've tried with the unclipped wings and with the clipped wings version. I've tried with different liveries (but only those that came with this addon). I've uninstalled, downloaded v1.2.0 again and re-installed. I have tried with nothing else in my Community folder. If I uninstall v1.2.0 and install v1.1.0 it starts as it should using the checklist on the tablet. But uninstalling v1.1.0 and installing v1.2.0 I get the same problems again. What is causing the behaviour of v1.2.0 to be different from v1.1.0? i.e. No piston compression sounds when turning over and the low fuel pressure light going off before using the wobble pump? Why can't I start v1.2.0 from cold and dark using the checklist? Would appreciate any help please. Edited May 12, 20224 yr by Sender46 Spelling
May 13, 20224 yr I had problems starting it too, but I think I figured it out. When you first turn on the battery by moving the throttle the electric fuel pump is on by default now, that is why the pressure light goes out without the wobble pump. Switch is hard to see, so you might have not used it before. What works for me is to prime it until the tool tip changes from underprimed to primed, then use the wobble pump at least 4 times to restore the pressure after using the primer, then it starts. Light stays off the whole time. Hope that helps. MC
May 13, 20224 yr Author Thank you for that. I understand now what's happening with the low fuel pressure light, although the electric fuel pump being on before starting is wrong according to DCS's Spitfire guide (what an excellent guide that is!). I followed exactly what you said and it started, so thank you for that. Seems pretty screwed up though, compared to how it was in v1.1.0 and compared to the DCS Spitfire guide. I'm still not hearing the piston compression sounds like in v1.1.0 when turning over to start. Do you hear them with v1.2.0? Still no response from FlyingIron support, which is disappointing.
May 13, 20224 yr The electric fuel pump is turned on by default to allow Ctrl-E Autostart to work. Just turn it off before starting up and use the wobble pump like you're used too.. You do have to use the primer a lot more to get her started now. The flyingrion support is actively responding on their discord. Good luck and enjoy the Spitfire!
May 13, 20224 yr Author Thanks. I tried joining their Discord channel but it won't let me claim the account cos it says my e-mail is already registered, so I can't post there even though I can post on other Discord channels. Frustrating. I don't see anything on their channel about missing compression sounds when turning over on startup. Am I the only one not hearing them?
