Even weird is I try again, engage starter but leave the RUN/STOP button showing "Run" and the engine spools up????

Check your mixture axis and related controller settings. For some reason turbine engine ignition is tied to mixture position and that causes the issue you're observing.

Ok so I'm enroute, just loaded in an ILS - is there a way to step through the legs on the ND so I can check the setup of the approach?  I would have thought changing to PLAN mode would allow this but when I step through the legs on the FMC the ND doesn't move, its kinda hard to visualise the approach I don't trust the FMC with all the USR and USER waypoints it inserts??

I've tried several combinations and I am unable to to do an ILS approach. For my last test, I set up a flight plan, but did not actually use FMS as NAV SRC at all, I simply flew with the AP using Heading and Altitude and kept the NAV SRC on VOR1. When I was approaching the localizer track (with appropriate 'green diamond' movement), I selected APPROACH mode. Instead of holding the heading until I intercepted the ILS, the aircraft veared off toward the FMS flight plan and followed it, ignoring the ILS, which it actually passed two more times during the approach in the plan. AP NAV was never selected and NAV SRC was never on FMS at all.

Does it do this with the RNAV's as well?

Why would that matter?

And the ILS was tuned in to NAV1?

Most approaches have the final fixes along the ILS path, so you should have already been lined up. But it may be a case of the sim AP thinking your active leg is somewhere further back on the plan, and thus not eligible to switch to APP.

That being said, the sim autopilot has some pretty strange behavior that is outside of our control at the moment.

What method are you using to step through the legs?

I'm changing the ND to Plan mode then skipping through the legs on the FMC?  Other than that I'm lost lol.

"And the ILS was tuned in to NAV1?" - Yes.

"Most approaches have the final fixes along the ILS path, so you should have already been lined up. In all the tests where I was using the FMS flightpath", -  I was. I switched to ILS to do the final, but it never followed the glideslope. That's when I tried a test which just used AP heading with Approach - should have been fool-proof. The fact that I started following the FMS when it wasn't even selected as a NAV SRC, brought me back here.

Interested in trying? - VERY short and simple flight plan from Travis AFB (KSUU) RWY 21L to Sacramento (KSMF) RWY 34L. (ILS is 111.10 but of course that is automatically set up). I flew at 2000 feet the entire flight. In four or five attempts, I've never got ILS to bring me in.

I'll definitely give it a shot. However, all the aircraft code does is tell the sim AP "hey, we're in APP now" when you press the button. That's literally the extent of it. After that, it's all the sim hardcoded AP behavior. So, if it does in fact not work right, there may not be anything we can do from our end at the moment.

That's being said, we are working on some stuff to bypass the sim AP altogether for some things that may bring solutions to this kind of stuff along with it. We're definitely looking at every available angle.

Sorry to keep harping on this, but I did one more test. After entering a flight plan and starting my flight, part way in I switch AP to Heading and headed for a different runway. I manually tuned the new ILS freqency in the FMS using the TUN bottom. I set my heading to intercept that ILS. This all should be completely valid, if a bit unorthodox. As I approached the intercept, I pressed the APPCH button.The aircraft veered off and headed back to the FMS flight plan, ignoring the ILS completely. Again NAV SRC was VOR1.

Well if ILS doesn't work now, just say so and I'll get off your case! LOL 😁

I'm pretty darn sure it was working in earlier versions of your mod, so I was assuming you'd messed up somewhere. Sorry!!

I've flown quite a few ILS approaches, including two today that are up on YouTube... Maybe you can share a screenshot or video of how you're trying to do it so we can help?

You can step through the waypoints on the MFD by setting it to PLAN mode, which you did, but then you need to go to the MFD ADV screen on the FMS.  From there you can select to center on the current TO waypoint or step forward or back in your plan.

Heh, well, I wouldn't say that it doesn't work per se. Just that we have had reports of folks seeing the AP do bizarre things and ignoring approach mode. So, it was more just a heads up that you may be running into the hardcoded limitations at the moment.

That being said, I personally have had decent success doing it, so we may be able to dive into it further and help you out, as @cwburnett says.
