Tell you what not winning every time I try to do a bit it starts raining. Rodetrain was thinking about your low power issue and was wondering if you changed the coper washer at the bottom of the injector sleeve. If you haven't it may be loosing a small amount of compression through that seal.
This is the injector bench test results for my #2 injector. You can see the leakage rate is quite a lot measured in mm cubed per hour. This is fuel that is released back to tank by the injector solenoid. This causes the hard starting because the fuel rail cant be pressurized properly. It also creates an over fueling situation as the solenoid stays open longer. Managed to finish off fitting the new injector this arvo and starting is much better but haven't been able to test drive it yet. I need to visit Nissan tomorrow and get a return line T-piece as one of mine is leaking.
Righto finally finished off the job. A new return line (comes as an assembly) from Nissan costs $55, should have taken more care on dis-assembly. Been for a test drive and power seems good, starts ore 100% better, but still have a small amount of smoke that I am putting down to the turbo oil seal. The pooy is at the auto elecs getting the A/C sussed out so it will be interesting to see if that uncovers any other issues. All I have to do now is decide whether to risk a Chinese cheap nasty turbo or go with a proper Garret. Just to confirm what I have done; I have changed #2 Injector, I have not programmed trim codes or injector codes. As in heavy industry ie. mining, there is no need to replace all of your injectors just because one has failed. If you are going to have a crack at changing an injector just remember to use an assembly grease on all your o-rings and replace all your injector seals (copper washer and o-ring).
Joelshero. i have just sorted mine out, i did get a faulty injector. i replaced all orings and washers when i fitted new one. the big girls goin good now. but i have an oil leak from the rocker cover seal that i didnt replace:(. should of but tryin to save money. anyways all good
Good to hear its all good Rodetrain did you get another reman injector or a brand new one?
