  • 2000 GX CNG System Inspection

    Hey all, new to the forum! Seems like a lot of great information and people here. I just purchased a used 2000 Honda Civic GX that was a fleet car from the City of Atlanta. The car has 44,000 original miles on it and is in great shape. From the looks of the information that I have from the vehicle it seems to have been driven lightly and was decommissioned in approximately 2012-13. So it looks like it sat around in a lot for awhile until it was sold. I have been driving the car as a commuter for the past several days and have put on about 800 miles. I have since replaced the spark plugs and wires and the motor runs great. I have started to notice that when I step on the gas it sometimes makes a noise that sounds like a constant dial tone, almost like the noise the old radios would make when you stepped on the gas. My question is.....Can I inspect the CNG system to address the noise? I ordered a new high pressure filter and will change that shortly but was wondering if there is other things I can do to check the system since it is older and I am new to the CNG world.

    Thanks for any help in advance

    Good call on getting your fuel filter drained and replaced. The noise could be the fuel pressure regulator diaphragm vibrating?

      The year and mileage reveal that your car has the VIN# 1HGEN1641YL000558. Two prior times it listed online, $2050 was offered in July and $3700 in Sept - both in 2016. The auction you won showed an answer to a question I posted, "Is a $4000 replacement tank needed because the fuel tank is expired on this car?" Answer: Tank expired 2015 . .

      I regularly scan online CNG vehicle listings and post the question so that novice buyers can be alerted to this expensive requirement for natural gas cars older than 15 (or 20, for newer tanks) years. I think this one ended up selling for $850 after people saw the expired tank answer posted. I own a 2001 GX and had the tank replaced at A1 Auto Electric in Fresno CA (there's also Lancer in Salt Lake City.)

      Aside from the manufacturers of lightweight tanks (as opposed to the heavy tanks used for welding gases) deciding to assign an expiration date due to uncertainty with the plastic and resin aging properties. The risk to the car owner would be in the form of getting sued in an accident for having an expired tank which contributed to the damage and injury. IT HAS HAPPENED. An aftermarket tank installer's insurance (not the Fresno or SLC shops mentioned above) had to pay out 6-figures even though the fuel line components didn't contribute in any way to the damages. But the car was "a CNG car" and this was enough for the lawyers to go after.

      As for the filter. Study this thread carefully to avoid danger working on the high pressure fuel line:

        I bought my '99 Civic GX back in 2010. Same situation - a fleet car in very good condition with low mileage. Mine had only 38,000 miles on it, and I'm now at 289,000. The humming noise that you hear is the fuel pressure regulator as John suggests. Mine started making that noise a couple of years after I bought it. I changed the regulator and it has been quiet ever since. CNG Specialists in Oklahoma City can rebuild your old regulator. Call them at (405) 677-5400.

        Since it was a fleet car with low mileage, it probably has the original, old, dry-rotted timing belt, which also needs to be changed. Along with the timing belt, change the water pump, timing belt tensioner, and front crank & camshaft seals, too.

        What kind of spark plugs did you use? It is imperative that you use the factory type, CNG spark plugs with the tighter .030" gap. The auto parts stores list many different spark plug options for these cars that will not work properly and cause misfires, especially at idle and low speeds because they are gapped too wide at .044". I suggest using NGK PFR7B (stock #4853) spark plugs.

          Thanks all for the great information. How much was the tank replacement from A1 on your 2001 and am I in violation driving the car with the original tank? I did find on there another post of someone with the same noise as the one I described and it was the pressure regulator vibrations. As for the purchase of the car. I bought it from the person who won the auction and it was not disclosed that the tank was expired. I guess it was too good to be true that the car was in such good shape and had not sold. I didn't know about this community until now and feel like I should have dug more to find out about this issue.

          Thanks again all

            What could have prevented a buyer not knowing the tank was expired would have been for the Arizona agency that sold the Civic to have drilled a hole in the tank and required car to be towed away by buyer - both of which were done by a Nevada government agency. Seems like a good way to avoid liability. Elsewhere in this forum may be found:

            The expiration date is the end of service date. No exceptions. It is usually listed near the fuel filler, or under the hood but is always listed on the tank itself. If it is a 15 year tank the service life is 15 years after the date of manufacture. If the shop you are going to is telling you something else, find another shop that knows the rules. The tank needs to be removed and then rendered unusable.

            There is no enforcement of the tank expiration rules. But, if you continue to use a tank that is past its expiration, then the liability is all on you. The tank manufacturer, tank installer, and the tank inspector are all cleared of any liability. Also see explanation found by using search term OVERWARP on home page of this forum and read thread TANK POLICE

            Or read more at this thread:

            My tank replacement invoice from A-1 Auto Electric in Fresno was $4160 in May 2015. Best thing is that they buy tanks in bulk quantities and have lots of experience doing the tank replacement, so they get it right the first time. As already mentioned, these cars can reach 200K to 400K miles.

            Begin by asking here if they do tank replacements:

              I bought a used Honda from an employee of a tow company with an expired tank. I had never heard of CNG but was told by the seller that there was nothing wrong with the tank and that it gets inspected every 3 years and that's it. And that it was just smogged and inspected but he misled us. I paid 1800 and went to pg&e to set up an account and was given the bad news. The tank expired 3 years ago in 2015. My lawyer thinks this could be a criminal sale but certainly fraudulent. The seller claims he had no idea it even had an expiration date but he read the part of the label to us aloud that mentions the inspection but he omitted the expiration.

                The vast majority of private owners and used car dealers have no idea.

                If this car was purchased at an auction and then flipped to you by the seller, these are always disclosed at the auction. You might have a shot at small claims under misrepresentation ( where the seller did not know but should have) or fraud ( did know and concealed). Used cars are as is, unless otherwise in a written contract. I am not an atty, so take it with a grain of salt.

                If you cant reverse the sale , sell it. Car condition and miles ?

                PG and E is one of the few fuel providers requiring high pressure fuel system cert. to use their facilities.

                PS: If this car never had a white hov sticker issued in CA,, Run to the post office with your ca dmv request form , certified mail, for a red hov sticker. must be into the dmv by end of December. If it has had a white hov sticker, it expires in Jan and no replay.
