Having problems starting the civic..

After doing the turbo conversion, ive obviously knocked something etc.
Anyway, symtoms are:

Cranks over, but doesnt fire. It will randomly give a fire and you can hear it, but will generally just keep cranking.
There is oil pressure, spark, fuel. I took the 450cc's out and put the 240cc's in with the standard ecu, and still same problem.

Someone told me to make the earths better, so i made a few more earths onto the engine but still same problem.

Now the car did run using a pm6 initially. It would have been running way way to rich, eg double the amount of fuel, but it did idle for about 10secs then died.

The ecu im going to use is a PM7 chipped using turboedit for the 450cc's and boost.

The injectors are getting power as well


Only thing i can think of is spark plugs, or dizzy fukt? The car ran 100% fine before i started turboing it.

Thanks
