Hey guys, I am new to all this sort of stuff. So i need some advice. I can smell petrol in my car, and don't know what it could be. Is this a common problem or my car specific. And any ideas on what it could be? Is it easy to fix? a way to troubleshoot? I appreciate any advice. Anything you can think of i can always get my brother to help me fix (he is more mechanically sound then me). Thanks guys
Running rich by the sounds of it. Check spark plugs and have a forum member run a conzult scan over your car to see if your O2's are working.
this could be correct............ BUT..... it is definately worth checking all of your under bonnet hose clamps for loose connections and split/worn hose. these cars can and will develop major issues(including a strong risk of under bonnet fire) if the fuel hoses and clamps are allowed to deteriorate. depending on how strong the fuel smell is, i would try to avoid driving it as much as possible until the source of the problem is identified. where in Perth are you, id be happy to have a look with you, give you a helping hand.
i would check your fuel lines for leaks (checking the rings (brain not thinking today) are tightened on them), is the smell coming from the front of the car? I would not drive it till you fix it.
if its from the rear of the car its probably o2's which have gone (same as mine) however mine is much worse because my cats are stuffed.
Not driving it will be an issue since its the only car i got and i work every day. I will have to try and swipe by brothers bike. Jinxed - I would really appreciate your help please. I am up in Mindarie. But if your willing to help I can come to you? Just a bit worrying at the moment haha p.s cheers for the advice guys. I will look into a few of the things mentioned tonight if I leave work in time :/
Also I'm not sure where the smell is coming from. I only smell it once i start driving. Not to sure how to tell where it's coming from.
had the same issue and I changed O2's.. Got better but can still smell a strong fuel smell when it's cold. All fuel lines are fine.
fuel smell when cold USUALLY means a fuel leak jamie. when you say all lines are fine i assume you have checked (and preferably replaced) all of the following. often smoe of these get missed when tightening clmaps etc. 1) fuel feed line under battery tray 2) fuel line into back of fuel filter 3) fuel line form filter to balance tube and all the little lines on there. 4) fpr and fuel dampener 5) small hose under front plenum runners connecting fuel rails together.
Might go over them completely when Ryzan is down. He'll be able to point me in the direction. Though him and I have already gone through all fuel lines in the engine bay.
I had my fuel lines replaced. (Well that is what the receipts say) I wonder if the fuel smell is noticeable under the bonnet on a cold morning, when the key is turned (but before the starter motor turns over). I used that tip to diagnose my fuel line leak. Sniffed around until I found it. The old clamps were used (which is normally OK) but one of them must have been damaged when removing, so it pinched a hole in the new hose when it was tightened. I replaced one piece of hose and one clamp.
I have a strong fuel smell in my car. I know it's not running lean I know it's not leaking in the engine bay I DO have the tiniest of pin pricks in the fuel tank, but I doubt I'd smell it so strongly due to that. I have no O2 sensors because my car is a haltech and it's map sensored I have no charcoal canister because the previous owner deleted it The last two points, is that likely the cause of my smell? If so, how do I overcome this?
try tightening them when the car is warm. you can usually get another 1/4 turn on most clamps easily enough. also, no worm drives. they are shitty and dangerous on fuel lines as the pinch and tear the lines. fuel line specific clamps only.
Not exactly engine bay related, but... Fuel filler neck. The threaded insert into the throat of the fill pipe. Needs new sealant. Also, under the parcel shelf are the top access covers to the fuel tank fuel pump access hole. The seals under the in cab access covers perish and allow fumes to enter the cab, (replace with strips of high density foam of similar size). But also the oring under the tank access panel might have swelled, allowing fumes to exit the tank (buy a new one and replace)...both of which can give you fume odors in and around the car. If and when cold, its probably just a leaky fuel hose in the engine bay. Depending on how strong a smell it is, its either a small leak which really only lets vapor out, or if its a strong smell, i would look at replacing all the fuel hoses asap. For a few meters of EFI!!! grade fuel hose, some new clamps and a beer whilst at it. Its the best insurance you can have. Really doesnt take all that long to replace 80% of the hoses.
On principle i would agree with you. Full faced efi hose clamps are the bomb when doing this job. But worm drive clamps can be just as good, failing you know what you're doing. I use them all the time when i cant find efi clamps. Just have to nip the new hose tight, not strangle the bejesus out of it.
I have a funny feeling there are vents in the boot under the plastic panels... Drain holes? Port holes for releasing cabin pressure when closing doors...
is it after you do a sharp right(or left...cant remember) turn, as the fuel neck filler generally leaksa bit
