fuel injectors or the rail? how to change.

[dvdevo]

Ok my leaky injectors seem to be not because of messed up o rings.. So i guess i should buy new injectors? I dont want to order online because it takes too long. But i'm opening to reccomendations for sites that sell them. Or if there is a place near sanfrancisco then that would be great. But anyways, i was lookin at the injectors, and the ones that were leaking all didnt have a plastic cover thing around the injectors, i assume the previous owner tried to change it. BUt while changing the injectors today, gas started leaking when i took the injectors off? Is there a way to prevent the fuel from leaking? and..the picture with the white circle, that part is being held by hoses, and those hoses didnt have clamps and i dont know should i just try to yank it out or not.

Should i just goto kragen to buy some injectors since it'll probably be cheaper than going to the nissan dealer. Which sizes i need? Thanks. I have the Chilton manual but it tells me to disconnect some stuff but they're all acronyms and i dont know what is it.

Disconnect the main fuel line...and bleed the pressure first.

Their will be residual fuel remaining. Let it all pour out.

Take off the fuel rail and the injectors. Dry the injectors and clean the sockets maticiously. Again, clean the outside mating surface of each injector.

Slip the O ring (like a condom) up the injector shaft and make sure it seats properly.

Make sure the fuel rail is not bent. Reinstall and they all should seat properly with no leaks....but if the fuel rail is slightly out of alignment, some of the seals will not have enough pressure to seat...so watch for that.

The key work is CLEAN everything properly.


I wish you well.

Should remeain dry...unless the injector itself has a leak seeping from it before the O ring.

If you buy new injectors, send your old ones to me. I will pay..I am collecting old injectors to see if I can rebuild and mod them properly.

Got some coming from transient in hopefully 7 days..

where is the main fuel line? is it connected to the rail? is it shown on my picture.. yeah i'll send you the injectors..uhh how much do i sell it for? but anyways, email me your address or something so i'd remember.

oh and the plug that goes on the injector, how do i take em out, the manual doesnt say.

We have private messinging, or use [email protected]

(look at the button user cd)

The injectors have a plastic insulator and the wires simply unplugg from them.

For your advice, many times, this plug can go bad having too much grease and residue around it.

These must be clean and the plastic insulating cap clan as well. If your fingers get dirty doing this, then "conductive residue" could keep voltage from getting to the injectors properly...and especially if they are gummed up.

Just carefully unplug the wires from them.


The main fulel line comes from the fuel filter on the passenger side fender area. Follow this line and undo it...the other rail line is the ventilation line to the tank and emmissions.


Look at the filter, follow the line, that is main input...and it can spray 20 foot streams of raw gas under pressure so beware!

got to roll it up eh??

The injector is a short fit...

the condom...............................

but they just slide right in right? and when i put the injectors in..it doesnt like require force? except when i screw on the rail back right?

to relieve the fuel pressue in the system, pull the fuel pump fuse out, its in the fuse box on the passenger side under the hood, start the car and let it stall!! most of the fuel will be gone, and there will defenitly not be and pressure to shoot 20 feet.

thanks for the fuse taking off tip.
