Video is not working here either. Just the sound.

From PM

"Have you got your fuel lines hooked up the right way around? The in and the out are both at the front there, and there is an FPR on the outlet end and there is a pulsation damper at the inlet end. The inlet goes into the front end of the rail and the outlet comes out of the back end and then runs back up to the front. If you hook it up backwards, it won't work. "

It doesn't sound like fuel pressure slowly bleeding off. If you pull fuel pump there will be a moment where it runs rough as it leans out. I could be wrong but it sounds like it just shuts off as if someone turned the key off. My first instinct is pull ECU logs and see what's going on the moment it dies.

Yeah most definitely just shuts off exactly like that, yeah I'd most definitely do that but don't have a consult adapter....

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
