Electrical issues! Help please? :)

Hey guys!

 

a bit of background, iv been doing a single turbo conversion on my bh5 (its not really your standard single turbo setup though pic below of while it was being built up) followed the guide on the single turbo conversion off of here (bloody awesome by the way) i got it running for a little bit then it shat itself and iv just left it parked up for past couple months out of frustration ahaha. It's also got a g4 sitting in it  

 

My car is a sack of S*** basically but i still love it. When I did have it running for a moment and took out for a quick test drive a while back now and on the way back it started to run like S*** then all power would completely cut out except dash lights, it was kind of hit or miss if it'd even turn over (I originally thought ecu might have been preventing it from turning over). 
Now it will always turn over but never starts. 

 

Other issue that's just recently popped up was that if you turn the ignition on then take the key back out the dash lights (cluster and boost controller) are all staying turned on with abs light and engine check light. I'm guessing I've somehow manged to F*** with the wiring somewhere, maybe grounding out somewhere or something?

 

Last part is that the ecu refuses to connect to my laptop, read that could possibly be a fault in the ecu? 

 

I realize that I might not get fully accurate information but brainstorming and trying to figure out what my next steps should be which would be a huge help to get my baby back on the road
