Hey,
I can't really help you in detail, I'd recommend flat-bedding it to a reputable workshop, but some basic things that come to mind:
- You've probably blown many fuses from this, so check them all
- Start motor could be seized, may need a hit with a hammer, may need a new one,
- fuel is obvious, but pump could be seized or lines could be clogged, injectors could be clogged, (some or all of these can be cleaned or tested?)
multi-meter will be your best friend in troubleshooting
If you've reset the ecu, chances are once you get it ticking over it still may not even start, or it may run very rough, someone with Vipec experience may be able to confirm this (base map?), either way you'll need a tune pretty quick.
