as the title, my mate has a problem with his civic.

going down the road shortly after turbo conversion the boost gauge didnt go over 10 psi and was only half throttle till 4 - 5000 rpm and had a big backfire then struggling to stay running and eventually stopped. shortly after stopping it attempted to start then made knocking noises and coughed and spluttered then stopped as a nice puff of electrical smoke came out of the engine bay...

thinking maybe ignition system or something shit itself

now will not start... fuel pump is priming and there is no huge puddles of oil so ofcause it hasnt thrown a rod or anything.. will crank fine but no attempt at all to try to start.

any advice would be appreciated my mate is very keen to get it going again.
