I tried working through both tutorials, but no matter what I do I cannot get the left engine to start. Right engine, no problem.I saw an earlier post that said the update should resolve the problem, so tonight I uninstalled the 737 using the uninstaller provided by PMDG. Installed verson 1, then the applied Service Update 1, and then applied the mini Service Update 1-1.No change though, the left engine still will not light.I'm pulling what's left of my very little hair out over this issue.Can any kind clue me in to what the problem might be?CheersSatchmo

SatchmoReinstall the Base and download and install full SU1.1 instead of SU1 and mini SU1.1. Could do the trick...Hope it helps,

Hey, Hit CTRL+F4 before you move th eleft-engines FUEL CUT-OFF switch to ON! I assume this is because of the way PMDG have programmed the Cut-Off Switches which obiviously vary from the MS Default system!
