92blackz34 Posted July 24, 2004 Report Posted July 24, 2004 i have a 92 lumina z34 and im looking at changing the injectors. how do i unpressurize the fuel rail? and after that do you just swap them out and its done or what else has to be done. Quote
Canada Posted July 24, 2004 Report Posted July 24, 2004 Just use a pressure gauge and valve at the the test port.....or you can just pull the injectors out of the fuel rail....there is only about 35-40 psi behind them. Yep...just swap them out........replace the o-rings and your intake and EGR gasket. Quote
stlunatics2oo3 Posted July 24, 2004 Report Posted July 24, 2004 well what i did is push in on the shroder valve or how ever it is spelled with a rag over it and bam its all good just like lettin air outta tube oh yeah for sure cover up your intake ports when doin this so nothin falls in and also when you pull the injectors out cover them too just a fyi and a safty tip Jeremy Quote
