Won't turn over, fuel?

[sblake01]

I don't have a filter there on my car. That's an add on that some people do if they're having problems with contamination in the gas tank. The only real cure for that is to drop the tank and clean or replace it. Short of that, the filter you have appears to be a universal one, not a Nissan item, and you should be able to find one at an auto parts store. Just make sure it's for fuel injection and it has the right size nipples (5/8"). You mignt also want to consider replacing the factory fuel filter under the hood.

I believe that it's a Fram G3 filter that fits the hoses (i have one on my car, helps out a lot since i can't drop my tank yet) it goes BETWEEN the gas tank and fuel pump, so it is under negative pressure. It doesn't need to be for an EFI system because of that.

(article on it that i found)

http://www.atlanticz.ca/zclub/techtips/fuel/g3filter/index.htm

and from the looks of it, you need a new filter. It almost looks like it's leaking where the white and clear plastics meet.

First off, depressurize the system in the way detailed in Stephen's post.

Your plastic filter is not intended to be mounted on the outlet side of the filter. It is not capable of handling that amount of pressure. IF you must have an additional filter (it is not original equipment), it should be between the tank and filter.

Once you have it removed, check on the condition of the little cone filter that is in your fuel pump (assuming you have the original pump).

If you are concerned about loosing too much fuel, clamp off your fuel lines with padded clamps so you don't mar the rubber.

If that much crud has accumulated in the little filter, I would imagine that you have quite a bit elsewhere in the system.

While the system is depressurized, you might as well replace the fuel filter that is located in the engine bay, as this is likely clogged as well.

Don't reuse the clamps that are on your car right now. Pony up the additional few bucks and get fuel line hose clamps. They are designed to not pinch or chew up the rubber and provide a uniform amount of pressure from all sides.

Depressurize LOL I think she's already depressurized man with that massive leak going there. That's why she quit running on ya along with the other issues. Your going to get at least a little fuel on your hands no matter what. It's part of working on cars Just think safety and wear eye protection and if fuel gets on your hands or arms, just wash good with soap and water.

But yeah, the photo stephen is showing out of the factory service manual is the "Correct" way to depressurize the system.

Like I said in post # 7 "Gee wonder why the P/O added that filter" you can tell looking through the clear canister that gas looks horrible. Datsun never used a filter back there like that. It's just a cheap add on as a temporary solution. Once the filter gets junked up again and it will, the problem returns.

If it was me, I'd fix this right the first time and be done with it. Drop the gas tank, either get it professionally cleaned internally or just get a new tank, disassemble fuel rail and clean out the steel fuel tubes, clean & blow out fuel lines, Eliminate that added on aftermarket filter in the back and get it back to stock, reinstall freshly cleaned or new tank with all new rubber high pressure EFI rated fuel hose, replace the little filter at the inlet end of the fuel pump and do the same under the hood when reassembling. If injectors work fine, then I'd send them out to be cleaned. Once you get them back reinstall all 6 injectors with new top and bottom rubber 0 rings (use a little 3 in 1 oil on 0 rings when intalling), also inspect the plastic injector holders as these tend to crack and get brittle with age, reassemble fuel rail & components along with all new High pressure EFI rubber hose, new clamps (I recommend the factory clamps. those crappy ones you find at auto stores always dig into the hoses :sick: ) then install a new fuel filter under the hood located at the passenger side fender area and fill with fresh gas and then you'll be in damn good shape

Now this may be too in depth for ya both expense wise and your skill level for working on cars? I don't know but what I listed above WILL be the correct and permanent fix. Plus the other problem is your using your Z as a daily driver correct? No question these issues factor in and if so then I guess you can keep the added filter in the back that was added by the previous owner, repair all the leaks, and just continue replacing filters all the time frequently and just get by that way worst case senario.

Anyway just my input. Best of luck

thanks for all the info guys I'll buy the filters, clamps, and hoses and try to start tomorrow or saturday. I won't be able to drop the tank and everything else until I have more $, time, and better weather. Im at a decent level working on cars but my previous experience was almost all suspension/brake wise on my previous car.(coilovers, bbk conversion, adjustable control arms, etc.)

I was going to say all of that but after giving my input to the guy with the 260Z the other day, and seeing some of the reactions, I have concluded that speaking in terms of blatent harsh reality gets misunderstood. You remember, the guy with 60psi compression who was going to have a ring job done by a guy who woudn't touch his carbs or buy an engine from Craigs list for 300 bucks (with 5 speed!) and I said I didn't think either of those would solve his problems? I know that this post is a total digression but, I have to say, you've nailed my thoughts exactly!

[DatsunZsRule]

yep, not a problem Just do what you can do. It's no small project or cheap project thats for sure. Please keep us updated so we know how things turned out for you.

Stephen, I think I missed the post with the 260Z but I know what your talking about. Sounds like I didn't miss much.

[sblake01]

Sometimes I wished I lived closer to the guys that post EFI problems so that I could actually go look at the cars and offer my help. I've solved just about everything that can come up on these cars. I've even come up with a few better solutions than just standard fixes in some cases. But it's so difficult make suggestions based on reading rather than seeing it in person and everyone is so spread out across the country. Actually, the world.

[Cornbreadxd]

I didn't see that post either, I'll get all that stuff done eventually I just have to secure another car as a DD so I can put my free time and $ into restoration of the z.

[sblake01]

I do understand your situation. I sometimes forget how that is since I have three cars. I don't do quick fixes on my cars because I have something else to drive. The post you missed really wasn't much. I just get frustrated when I tell someone how to do something right because I've been there...done that, and others dispute my suggestions based on what they've heard.

[DatsunZsRule]

Stephen, I'm in the same category and feel exactly the same way but what can ya do? All we can do is help out other Z'ers in need the best we can over the 'ol computer. It's better than no info. or help at all I guess.

Cornbreadxd, You'll enjoy the classic Z hobby. It's expensive but fun and yes, a daily driver will help you out a lot.
