your method for unblocking the injectors wont work, but anyway, i doubt theyre blocked. first make sure youre getting pressure upto the rail. when you turn the ignition on can u hear the pump priming? if so next just crack the cold start fuel line if it spuirts out, youve got pressure in the rail.
next thing to check is if your injectors are plusing. they make a clicking noise when theyre working. if youre in the racq call them up and get them to have a look. dont tell them youve just finnished a conversion, just say it wont start. its unlikely theyll get it started but they might be able to give you some leads.
