Disregard, after reinserting into FSUIPC both commands and restarting, it's not working anymore... bug?

SOLVED PMDG support team, and Scandinavian13 put me on the right path. It was a FSUIPC (strange) issue. I've removed mapping of those 2 events: EVT_CONTROL_STAND_ENG1_START_LEVER70320--- 0: Idle 1: Cutoff EVT_CONTROL_STAND_ENG2_START_LEVER70321--- 0: Idle 1: Cutoff from my SAITEK double throttle kit and the aircraft restarted working flawlessy. Now i have reinserted the 2 events again into FSUIPC (first attempt without deleting the whole config, only the 2+2 buttons related to fuel cutoff) and it's working normally again Dunno why, old config reported: 2=P1,19,C70321,1 -{Custom control: <70321>}- 3=P1,18,C70321,0 -{Custom control: <70321>}- while new one, with buttons ordered at the end of file, reports 45=P1,18,C70321,0 -{Custom control: <70321>}- 46=P1,19,C70321,1 -{Custom control: <70321>}-

Ok, thanks for the tip. I unregistered to make sure the process was flawlessy (i also manually deleted all PMDG related folders). Next time i will keep the old registration key alive! Yes, i'm using FSUIPC for calibration. You colleague @PMDG HD asked me to remove FSUIPC ini file and retry that way as soon as i get back home. I'll answer here and on ticket itself. I will make a copy of the INI file before removing it in order to be used in case this activity will be resolutive, so we can send the file to Dowson and/or PMDG for hardening or bugfixing or simply knowledge sharing. Thanks!

Small update: i noticed that when engines are not running i hear the first stage, but i cannot hear the engine noise. Fully removed P3D and reinstalled everything, i tried also an engine start with external bleed pressure from cart... No way... at first attempt the engines won't start (and vibrations stays at zero) Let's see what happens on PMDG support side

I definitely think it's a bug on my pc. I unregistered, manually removed traces of pmdg in my folders then reinstalled and tried with default cold and dark. No way. I've opened a support ticket to pmdg. I will let you know about answers, if any. @Spin737 I have tried everything, all combo. The only thing I've not tried yet is to replace JP4 with prosecco 😁

I've tried also with fresh restart using dual bleed technique. Same result. Here some screen with bleed from APU only, explaining the issue: Just after putting engine 2 into GRD mode. Notice TAT = OIL TEMP of engine 2 Engine is running at nominal values but N1 won't increase over 19.7, OIL temperature is 9 degrees, oil pressure risen to 31 and N2 is nominal Increasing ENG 2 won't increase engine rate, N1 stays at 20,3. Fuel flow is normal, oil temperature is still 9. CONFIG on CTR fuel is not an issue in that case

Well, i've read a lot about that, including B737 manuals... in that case i will run into a DUAL BLEED issue, with possible damages due to APU bleed air being counteracted by engine bleed... I'm missing something?

well, to avoid confusion, the FIX paragraph is "how i'm actually getting rid of the issue"... i don't have a fix yet...

Hi There, i have a problem that is struggling me, and i've checked almost everything on the net before begging you. PMDG 737 fully patched (800) Engile start issue. P3D 4.2 (same issue with 4.0 and 4.1) Situation: APU RUNNING FUEL PUMPS ALL ON L&R PACKS OFF ISOLATION VALVE OPEN (but tried also with AUTO) ENG 1&2 BLEED OFF APU BLEED ON (at 10 psu) Issue: Starting LEFT engine (starting RIGHT same result) -> Selector to GRD APU pressure goes to 40 PSU N2 start rising, Fuel flow start rising Oil pressure start rising AT 25% N2 (tried also at 20%, same result) i'm opening fuel valve N2 continues running up, N1 start rising, EGT start rising, FF initially goes to 0.6 then lowering to 0,3 OIL TEMPERATURE WON'T RISE -> N1 STOP RISING at 20% Everything seems NORMAL except OIL TEMPERATURE that stays at external temperature and ENGINE that won't spool up when applying thrust power. It seems running normally but... not running at all... I started also a normal default aircraft before starting PMDG. Same result Fix I'm removing fuel from badly started engine and then reapply GRD, engine spool up again and at 25 N2 (tried at 20 too) i provide fuel. Same result... Same result occurs if i start running the other engine... at 2nd or 3rd attempt temperature start rising normally (oil temperature) and engine goes UP with N1 to normal levels. PMDG is fully patched... i didn't found anything on internet for that issue that is struggling me... Any suggestion?
