Night Fury Posted July 22, 2008 Author Report Share Posted July 22, 2008 OK THEN!!! Get a load of this. Because of you guys, and because it makes since, I told my dad it was most likely a fuel injector. Rewind a month or so... I took it to our trusted family mechanic and I had injector in mind even though the problem was not hardly one... He told me the injectors "never go bad" and he was going to charge $80 just to look at it! FF to yesterday... My dad made me bring it there. Well, It got towed. My dad laughed at me for thinking it was a FI. Sure enough, It was!!! The place quoted me $320 to replace ONE fuel injector!!!! BS!!! So after a bit of gloating, we decided we will do it ourselves. So now I need more help!!! How do I replace a FI? Quote Link to comment Share on other sites More sharing options...

Addicted to eaton Posted July 23, 2008 Report Share Posted July 23, 2008 Maybe I am missing them? It would be in the first book, would it not? Read threw the content’s buck, It should say something about injector’s maybe under fuel delivery. My book say’s fuel systems. Your car is MFI right?

Addicted to eaton Posted July 23, 2008 Report Share Posted July 23, 2008 Disconnect the battery. Then relive the fuel system pressure. Detach the injector electrical assembly then remove the fuel rail,then remove the injector retaining clip. Then remove both o ring injector seal’s and throw em away (your going to need new ones) Also you might need to remove the intake plintem to get axcess to it.

Crazy K Posted July 24, 2008 Report Share Posted July 24, 2008 pcv valve and pcv hose (S or L shaped specialty hose depending on motor) and get the giant $8 tube of dielectic grease if they have it (permatex 6 or 8 oz) try advanced perhaps?

Night Fury Posted July 24, 2008 Author Report Share Posted July 24, 2008 3.1. The pcv is under the tube that connects the intake to the crankcase, correct? The tube is fine... Quote Link to comment Share on other sites More sharing options...
pontiac6ksteawd Posted July 24, 2008 Report Share Posted July 24, 2008 Make sure you have those injector o-rings ordered. Every AutoZone I have been to has to order them. But Advanced seems to carry them in stock. When you take the plenum off, make sure you cover the ports with rags. Dont forget to get a set of intake plenum gaskets, EGR gasket, Throttle body gasket. Have a shop vac, or a regular vac handy. When you pull on the injector wires, the looms break apart something bad. Just use the vac to clean up the gunk befor you pull any injectors. You dont want that stuff in your engine. You might think about changing your Distributor O-Ring gasket while you are in the engine this far. Its only one more bolt. You might also think about ordering a vacume line set from your local GM dealer. Without a doubt, as soon as you start getting into that engine, those lines will break, without fail. Your looking at a mess of 10mm, 13mm, and a couple 15mm bolts. Make sure you remember where the go back to. The intake plenum bolts have a couple piggy back bolts. Those need to go back into the same place. There are a couple 13mm nuts on the back side of the plenum that people always forget about when taking off the plenum. There will be 3 of them. You only need to take off the top 2, leaving the lower 3rd one alone. Dont foget to take off the large vacume line that goes to your brake booster. Lastly, make sure you dont hurt your EGR metal line that goes to the exhuast cross over. You have a specific model I beleieve, and is no longer available anywhere. The TGP's use the same one, and are nearly inposible to find in a junkyard. Quote Link to comment Share on other sites More sharing options...

Any particular brand injector? Quote Link to comment Share on other sites More sharing options...
pontiac6ksteawd Posted July 24, 2008 Report Share Posted July 24, 2008 I cant recomend any injector. I went to a salvage yard, and looked for a decent milage 2.8/3.1, ohm tested them, and put them in my car. Cost? FREE!!! I love pocket parts.. Details, uhm... I am sure someone else might be able to chime in about it. I know I have replaced 4 of them now, but couldnt tell you how to do it cause its all automatic to me. You can buy the vac line set, and if you need it, you got it. If you dont, you return it if they will let you. Quote Link to comment Share on other sites More sharing options...
bodeen2007 Posted July 24, 2008 Report Share Posted July 24, 2008 1. Fuel injector.-What brand? i use delphi a little pricey but their worth it . Quote Link to comment Share on other sites More sharing options...
BXX Posted July 24, 2008 Report Share Posted July 24, 2008 USE MOTOR OIL ON THE O-RINGS!!!! Not other stuff... Oil will also make it much easier than di-electric to get them seated. I have done sooo many in 2.8/3.1 engines and good ol 5-30W is the best for ease.. Quote Link to comment Share on other sites More sharing options...
