Im a newbie on here... - Page 2

Is that the top of the fuel pump.

No, that is just a schematic of the EVAP system. The fuel tank is '9' on the image and there are other lines running off of it. One to the charcoal canister and the other (rather large one) is the fuel fill neck. One part of the system that is missing is the vacuum line that runs from the EVAP purge solenoid to the intake manifold. This line is required to pull the vacuum on the system during its check. A small leak like what was detected could be in the vent solenoid, the fuel cap, or could be a bad seal on the new fuel pump/sending unit assembly.

Who knows, but start off by making sure that you properly tighten down the fuel cap and don't overfill the tank. Have the code cleared and see if it comes back. If it does, you might have to look at buying a new gas cap.

If that doesn't fix it, more investigative work is necessary, ie. inspecting the vent solenoid and purge solenoid as well as all of the vacuum lines in the system.

If that yeilds no results, you may have to drop the tank, but try everything else I suggested first before going through that ordeal all over again.

Okay well i always tighten it w/like fifteen clicks, that might be an exaggeration, but i do click it alot so i know it wouldnt be that, umm..the one other one that it could be is just the gas cap as being bad, so ill try that tonight, and clear the codes and see how that goes. If that dont work, ill ask you how to do the other things youa re talking about because i honestly have no idea what those are lol, and i definately dont want to have to drop the tank again. I know i put all those wires back up to fuel pump on really good, so i dont think they are those, but you never know, it was my first time ever putting the pump in and back up so ya never know. I appreciate all your help, it's not everyday you find someone that takes time like that to help out some one so i appreciate it. But ill try those tonight, and have him clear the codes and see if that helps anything. If not ill definately let you know. Im trying to go the cheapest route possible because im on a fixed income. But thanks again, and oh yeah go check my blazer on the photo gallery, i love it, i just took those pics last night also. Ill be posting some up of day time as well. And when it's clean.

One other thing im thinking it could be is that whenever i first put the fuel pump in, i was low on gas and didnt want to kill the car while i was filling it up so i left it running while i filled the tank up, and i filled it up almost over filled it probably, so i know that it could be that, and one other thing, on the actually gas tank neck part that goes up to where you put the gas tank on, there is that like hose that comes off of the neck about an inch away and connects back to the gas tank as well, i heard that had something to do w/the air or something, and that was really loose when i put it on, so that could be it, i hope not because i definately dont want to have to drop the tank again, and i know it might be that for the simple fact that it doesnt have a clamp on it, and i had to force it down on there. So you think that could be what's going on with

Well, anything that has to do with the sealing of the gas tank can be suspect. The smaller tube you spoke of is so the main filler neck doesn't get air locked and spew fuel back out at you. It is actually called the 'vent hose'... Anyway, there should be a clamp on both the vent hose and the filler tube. That right there could be your problem. The proceedure for changing the filler neck and vent hose assembly does not include dropping the tank so it should be fairly straight forward. Not to mention that you don't even need to disconnect the vent hose to put a clamp around it. Click on the pic at the bottom for a look at a 4 door filler neck arrangement. '1' on the pic is the filler neck ground strap and '2' is the connection between the filler neck/vent hose and the fuel tank.

Anyway, I try to help out whenever I can. I need to stop doing it when I'm at work though... Gonna get in trouble sometime...

mines actually a two door, and it does have clambs on the actual neck but on that part w/the air in the neck that one does not. So ill check everythign you said hopefully tonight, if my girl still isnt mad at me, cuz we got into a fight, and if so ill let you know how it goes, ill go to autozone and get them to clear the codes after i get a new gas cap and see what happens, and if that messes up, then ill ask ya for further assistance and where actually to go check the other stuff out.

Ok, well then... For a 2 door, see the pic at the bottom.

Yes, not having a clamp on the vent tube could be the entire cause of the problem. If that is leaking even in the slightest bit, it could throw the code you have. I'd get a clamp on there and see how things go. After that, if the code still is present, I'd try a new gas cap. They do go bad and since GM has the EVAP system integrity check, they throw a code. The clamp shouldn't be all that difficult to get to (I wouldn't think), but I have been surprised before. Again, the proceedure for replacing the fuel filler neck on a 2-door still does not require that the tank be dropped.

Ok,...i think i know of a way to do it w/out dropping the tank, atleast i hope, so ill do that and see if that's the problem. But see the thing that is bothering me is that like today it kinda dogged down at one point, just like surged only one time though, so im worried whats up. so im not sure

I'm betting you are just hyper sensitive right now. An EVAP error will cause no drivability concerns, unless your charcoal canister is full of fuel and that is making its way into the intake through the purge solenoid... If that's the case, then you need to replace the charcoal canister and possible the roll-over checkvalve on the tank. You can check this by pulling it out and tipping it upside down. I've got some work to do, but I'll get back to you later on where the charcoal canister is located.

yeah i would appreciate it if you could tell me where this is located because honestly i dont work on cars but when i do, i do a good job and get it done roughly fast, so i dont know much of the charcoal canister or the roll-over checkvalve, so just let me know when you get back i appreciate it, im off work in thirty so ill check it when i get home, i appreciate it.

Another thing that is up w/it, it could be idle, i hate to say so many things w/out getting the first one fixed, but today i didnt even push on the gas and it for real just idling went up to 25 miles an hour even switch from first to second, so it felt, and im pretty sure it did because rpms dropped, and it hit 25 when i decided id go because people be hind me, so that was kidn of weird.

Ok,....im pretty sure i know what it is,..i went outside and started up my car, before i went to autozone and was gonna look where the air meter thing on the tank w/e that was you said, that i said didnt have a clamp on it, and that looked to be fine, so i was like what the hell, so then i go to the other sid eof the tank and i keep getting these little particles that are hitting me in the face that are wet, so i move to the side, and where the exhaust comes from the engine then connects to the cat i believe it's called, then exhaust continues to the back and shoots out there, its leaking where it comes from the cat, so i got to go get that fixed. Thanks for all your help when i get it fixed ill let you know how it is.

This is what was shooting back gas particles at me, and what i believe is causing the emissions.
This is the blazer we have been talking about.
If you look a little bit in front of the rear tire in this picture you can see a stain in the ground that was caused from about three minutes of the car running in idle and it dripping from where i took that other picture. The big stain towards the front of the car isnt mine.

Man does anyone know of a good photo hosting website that is free and can allow pretty big pictures.

So gas is leaking out of the muffler??? Wow, I'm surprised you haven't had a flame thrower for a tail pipe yet...

YIKES!!!

You might end up needing a new CAT before this whole thing is over. Way overly rich AFR can destroy a catalytic converter. Check your oil level, because if you are getting that much fuel out your tail pipe, I'm surprised the thing is still running... The new fuel pump could have blown out the FPR...

I wont have any money til friday, is it okay to drive it until then? So you are pretty sure that is why the ses light is on because of the emissions? So if i change out the CAT do you think there is anything else besides that, that i will need to go change?

Ok,....where it was leaking was just the tail pipe is what a muffler specialist told me today, he looked at it, and said that it was probably just water, one guy said that i should change the CAT because it was prolly bad, but i went to two other places and they said that the CAT was fine, so no on that. So basically auto zone said they cant clear the codes if its an emissions code, because that can be fatal. So basically my last option is to spend alot of money trying to find out what the hell it is at a dealership for them to look and see what's up.

Can't clear a code because it is emissions and can be fatal... Hmm.. BS!

Anyway, the only reason why I said that you may be in for a new CAT is if it was gas pouring out of the muffler. Condensation (water) in the tailpipe is a normal thing.

The Evap purge code will go away if it is fixed and successfully completes the tests it goes through. Replace the gas cap and see how it goes after a week or two. The Evap code IS NOT a life threatening (vehicle speaking) code. I repeat, IS NOT!!

Alright kewl, well before i go to dallas i will change my gas cap, an dthen whebnever i get back we will do something about it, like take it to the shop. Well mani appreciate everything you have done for me alot. So thanks alot. And one other thing what do you think of the blazer? She's a beaut aint she

Yeah, definitely nice looking. Get that one annoying code taken care of and you'll be golden.

BTW, where did you get your cowl hood from?

Actually im not sure, my dad got it before he passed away, and he got it for like 350 bucks, he was working at a car dealership as a paint and body man and that one came in and he paid for it instead of it going on the right car, so they ordered another one. She's nice though, i like it alot.

That is a nice hood. Sweet lookin truck. Cardomain.com is a good photo website. They allow you to put info about your car, etc. It's free, and easy.

Thanks for the comments i appreciate it, and yeah, cardomain is the next website im throwing some pics up on. By the way, just to let everyone know, i changed out the battery in it and after switching out the battery it reset the codes, and my ses light hasnt been on for over two days, and about 600 something miles, so it must of been something minor.

yea cowl hoods r pretty sweet

heck yeah, my topic is a hot topic, i mean my thread that is, that's kewl, first time ever to post on here and it's already a hot topic, just like me, cuz im hot stuff, lol, j/k, but ne wayz, the blazer's running good, no more ses light and so it's good, washed her yesterday and guess what, today it rains, that sux, next time im checking the weather. Gosh it looks good though when it's all clean, ill get a good pic of it during the day time and post it on here. -Josh, i really think i should of been able to join the top car of the month, lol..
