Ed, Thanks for your answer and I will check this out tomorrow, a follow up quesiton, dont want to show my ingorniance here, but what is the NVLD?
I have replaced the gas cap, it was the first thing I did. Also checking the purge solenoid, will it actuate immediately or when?
Thanks Ed that clears the NVLD up a little bit, I will check all the wiring tomorrow and hopefully that will be the problem, other wise I just may blow this thing up!!!!!
Thanks and will let you know how it goes
OK Ed, here is what I have done so far today. Mind you, I have reset the computer and have not code present at this time, however, in a couple of days I believe the light will trip.
At the purge solenoid I have 12 volts going in to it, since I dont have a schematic I will assume that the other wire is a ground of some type. Anyways, I hooked up a vacuum gauge from the line between the tank and solenoid. After about 1 minute of run time I was getting a steady 20in hg. , shut the engine off and it held the vacuum. I then went to the NVLD and checked the 3 wires for any kind of breaks all appeared to be good. I then started the vehicle up and I could feel the NVLD click it also clicked went I shut down the engine. Now, it only clicked when I started the engine not just turning the vehicle on with out engine running. I went back to the steel line that ran back to the tank and tried to pull a vacuum. I have a hand pump to do this with and at no time was I able to get any kind of vacuum. I blew though the hose and could hear air at the fuel inlet only, no where else. I tried the tape on the fuel inlet like you stated and still no vacuum could be created. At this time I have check everything and I am at my wits end. I am pretty good at stuff like this but the only thing I can even think could be a problem would be the ECU, however, I pretty sure I ruled that out because I disconnect the wires on the NVLD and the check engine light come on.
What else can I try
I hooked a tee up between the steel line going to the purge canister and the purge solenoid. After about 1 to 2 minutes of run time I recieved no vacuum reading. I disconnected the hose going into the purge canister and cover it with my thumb and was getting engine vacuum. I hooked it back up and recieved nothing. About 5 minutes later I started to get a vacuum reading of 2 to 3 in. hg. as soon as I shut the engine off i would lose the vacuum. I clamp the hose going to the NVLD, again about 5 minutes of run time I started getting the 2 to 3 in.hg., I again shut off the engine and lose vacuum. Now I also disconnected the hose going out of the purge canister out to the fuel inlet. I started the the engine thinking I would get some kind of vacuum buy holding my thumb up at the nipple. I did not feel anything. What I dont understand is I get engine vacuum to the canister but nothing I can feel out of the canister. I have started the car at least 20 times since resetting the MIL, it has not come on yet. I understand that its suppose to go through 2 failed cycles before it will trip the MIL, should it have done it by now?
Ed, I will check that tomorrow after I get off work, I took it off once and it looked fine, but I was checking for debre and/or fuel contamination. I did not look that close at the case itself. Ill let you know something tomorrow
Ed checked the canister today I found nothing wrong with it rechecked the hoses in the area and still found nothing wrong. At this point I am thinking about replacing the canister just to replace it.
The car has been driven over 150 miles with no MIL, however, my scanner pickup up a pending code of P0441
Ed I will check the lines again I just dont see anything. I had the canister off and blow thru it. I put my thumb over the two openings and tried to blow thru it and couldnt. I look at the rubber hose pretty hard today and saw nothing, however, they are a little soft, I was able to hold a vacuum from the steel line to the canister so its not that one, the middle hose is teed and goes to the tank and vent the third hose right side goes to the NVLD and that is also a little soft. I know those should be replaced but do you think being soft could cause this.
I didnt check the code, I just reset it after I set it off and yes I replace the NVLD, I give it a try again tomorrow and will let you know
OK, I think I screwed up, I was checking the vent line that goes from the fuel tank, Tees off to the canister and the fuel filler vent, anyways has I was pulling the rubber hose off the tee, it cracked. Now what I am hoping is it was cracked the whole time and me pulling on it just broke. So I am stuck now until I replace that Tee, now I think I will have to replace the entire line because the hose from the tee to the fuel tank is on of those plastic ones and it appears to be shunk onto the Tee. do you have the P/N for the line and Tee. I am really hoping this is it, the pain is I have to drop the tank now to get to the top. Good thing is I can inspect at that time. Will let you know how it all goes. Again I cant thank you enough for walking me through this
yeap thats it, can i just get a comparable tee and put it in? for some reason it looked like it could have a check valve in it. I checked the evac sticker on the car and it only shows a tee, if thats the case I should be about to do something with it. I have pulled several tanks and its not that bad as long as I get all the fuel out, I tried it once with a half tank and liked to killed myself LOL anyways this things has a full tank, I'm not going to siphon that out, so thanks for the tip, let me see what i can find and I will let you know tomorrow.
