rockfangd Posted August 16, 2009 Report Share Posted August 16, 2009 Hello everyone, I was wondering if anyone can give me some tips on my 2000 lumina. The check engine light came on after about 50 miles and the code is a small evap leak. The NYSI is due next month so i want to try to repair the issue asap. I hate dealingwith evap problems Thanks to all in advance for any help Quote Link to comment Share on other sites More sharing options...
cutty Posted August 16, 2009 Report Share Posted August 16, 2009 First thing i would try is to replace the gas cap. Quote Link to comment Share on other sites More sharing options...
rockfangd Posted August 16, 2009 Author Report Share Posted August 16, 2009 quite possibly your right. Normally that is my first step but it usually never solves my problem. I will try a new cap next week. Thank you. Any other tips of anything common to look for? Quote Link to comment Share on other sites More sharing options...
dodgethis Posted August 16, 2009 Report Share Posted August 16, 2009 If the gas cap doesn't work I have an idea. On my '98 lumina I had a similar situation on my car. It was an Evap problem. The code pointed to the Evap purge solenoid. What I found out is that the two plastic lines that go into the solenoid had somehow been pulled out. I just reattached them and put some electrical tape (Its the only thing I had at the time). The code went away as soon as i drove it around for a while. It has not come back since. I would check that just to see if thats the case. I have a 3100 block so I don't know if you have the 3800 or not. Quote Link to comment Share on other sites More sharing options...

rockfangd Posted August 16, 2009 Author Report Share Posted August 16, 2009 Where is this located? I know there are 2 things near the engine, one in the front and one in the rear Quote Link to comment Share on other sites More sharing options...
dodgethis Posted August 16, 2009 Report Share Posted August 16, 2009 if you have a 3100, the purge solenoid is toward the very middle back of the engine. I can't stick my hand back there to get it, so I had to take the coil pack off just to either remove it or look at. I will say when i put tape on the lines, I didn't have to remove anything. I was able to do on campus before class started. Quote Link to comment Share on other sites More sharing options...
rockfangd Posted August 16, 2009 Author Report Share Posted August 16, 2009 so possibly it could be the be the vacumn line that goes to the purge solenoid at the rear of the engine? Quote Link to comment Share on other sites More sharing options...
dodgethis Posted August 16, 2009 Report Share Posted August 16, 2009 What is the code that your getting? Check behind the coil pack and make sure the lines are connecting to the solenoid. Quote Link to comment Share on other sites More sharing options...
rockfangd Posted September 5, 2009 Author Report Share Posted September 5, 2009 Ok so today I changed the fuel cap so i hope this solves the problem. Now my question is Is it possible that the light could go off on its own? all monitors are complete and the evap problem was the only reason why The SES light came on. I dont really want to reset if it can go out on its own Quote Link to comment Share on other sites More sharing options...

I dont really want to reset if it can go out on its own  i've had my ses light go out on it's own a couple weeks ago. when i did the a/c ion the car i had the air intake off the car with the air temp/map unplugged and the light was obviously on. i put everything back together and took it for a 5 minute or so drive and it turned right off.

rockfangd Posted September 10, 2009 Author Report Share Posted September 10, 2009 Ok so i replaced the fuel cap, cleaned the filler tube, and did a visual under the hood. I then reset the light. I only made it 25 miles before the light came right back on SOB. I cant get it through NYSI with this issue. Does anyone know an easy way to locate the source of an evap leak without paying through the ass for a smoke test? Quote Link to comment Share on other sites More sharing options...
slick Posted September 10, 2009 Report Share Posted September 10, 2009 Does anyone know an easy way to locate the source of an evap leak without paying through the ass for a smoke test? Â Without paying for a smoke test, you could test signals at each part with a mulitmeter, while cross-referencing with a FSM at the precise moments. Â Or you could take it to a dealer, who can hook it up to a Tech 2 and manually work each point on the evap system. Â Or pay out your ass for a smoke test.

89SupremeCutty Posted September 10, 2009 Report Share Posted September 10, 2009 did you try changing the purge solenoid? Quote Link to comment Share on other sites More sharing options...
rockfangd Posted September 11, 2009 Author Report Share Posted September 11, 2009 Well i cannot find a used unit around here. What other vehicles would be compatible around 2000. Just to be sure the purge solenoid is the sensor on the rear of the engine that has a 3/4 pipe coming off of it that runs up to the front of the engine and also has 2 vacumn lines attached to it? maybe i can snap a pic. It is a PITA to get to lol Quote Link to comment Share on other sites More sharing options...

It is a PITA to get to lol  'told ya. Like I said the coil pack came off in order to get my hand back there, and actually see whats going on. Thats also when I have the hood taken off to do a tune up, I didn't want to roll the engine forward. Quote Link to comment Share on other sites More sharing options...
rockfangd Posted September 11, 2009 Author Report Share Posted September 11, 2009 lol. I am tired of pulling the coil packs off. I cant see anything obvious back there Quote Link to comment Share on other sites More sharing options...
rockfangd Posted September 27, 2009 Author Report Share Posted September 27, 2009 Ok so being confident in my work under the hood I came to the conclusion that the evap leak was not under the hood so i took it to have it smoke tested and found that I was close in changing the gas cap lol. The problem is with the filler tube on this car the tube itself is metal but there is a plastic insert where the fuel cap is inserted. SO it was pouring out between the plastic insert and the pipe. I went to the dealer and purchased a new filler tube, installed it and drove 76 miles and it passed NYSI flawlessly I havent seen the light yet and since thursday i have already gone 176 miles. Now if only i could fix the ABS issue Quote Link to comment Share on other sites More sharing options...
