hdi won't start

[Poodle]

That shouldn't make it smoke, is it white/grey smoke by any chance? My suspicion is that you've got a leaky injector or stuck fuel pressure reg, but that should show up when you look at the live data, provided you know exactly what you should be looking for. I've got a feeling Steve at hdi-tuning has done a bit of a guide on it that you could use for reference, but can't remember for the life of me where he posted it. Could be here or on his own website or possibly youtube.... have a google, sorry i can't be more specific.
