if you have had an injector out the fuel system will need bleeding i attach a pump to the fuel return line and suck until im just getting fuel and no air and then they fire straight up usually sometimes need a little and i mean a little squirt of easystart. if you have not recut the cylinder head face and end of the injector dont expect the copper washer to last very long. and as above usually if the turbo is shagged its a sign the oil galleries are sludged up there is a filter in the oil feed pipe to the turbo on these that block up as well. All in all they are a pretty dreadfull engine once they have a few miles on them
