If you have read my other post you will know i am having problems with a 1.7 gm engine sohc turbo diesel engine astra. It has stopped dead and is now getting no fuel pumped to the infectors. I have changed the sensors around the engine from a scrap astra and still no fuel is getting pumped to the injectors. I have also checked the poser to the fuel pump and its is getiing 12v through the blue and red wire when the ingnition is turned on so Im guessing its a fuel pump problem and not and engine ecu problem. Is it possible to chamge the fuel pump and fit one from the scrap car? I knoe they have an ecu in the fuel pump so i am concerned that this ecu will not be coded to the engine ecu in my car. ome threads seem to suggest it is some suggest that aslong as it is aligned it will be alright. Has anyone changed one before and did it work ok. At this point Im wishin i had the isuzu engine with the seperate fuel pump ecu!!!
