your piston rings are stuck and are not sealing properly as daft as it sounds its true you need to dissconnect the injector connectors 5 in total then turn the engine over for a while, make sure you have a battery charger connected. get someone to turn the engine over and reconnect the injectors one at a time you should hear the difference in the engine it should start to get harder whilst turning over if this is the case then your going in the right direction this process can take up to half an hour so be patient and stop and start the process every five minutes giving the starter motor time to cool.....good luck!
