Gas Smell With A/c On

[ndottaylor]

Guys, I need your help...

I started my car the other day and turned my A/C on and within seconds there was a strong smell of gasoline. I turned the air off, waited about 30 seconds and turned it back on. Still the gas smell. So i turned off my car let it sit for a few min and started again with the a/c on... no help. I live in TX and its too hott to be without a/c lol. But this doesnt happen everytime i turn on the a/c.

Does anyone know what's going on? I've never experienced anything like this b4.

The only repairs I've had done lately was having the catalytic converter replaced.

Thanks in advance for any and all help with this:)

and btw,... its an 01' 2.4

[surreal_awakening]

Look for a gas leak?

[itsbmw]

Umm are you parked when you do this? My cars exhaust gets into it when im parked but when I drive I get nothing.

The smell of raw gas it a leak as will have to be fixed ASAP.

Don't know how fuel is delivered on the 2.4 though. I had a "O" ring go bad in the fuel reg on the 3400

[[ion] C2]

don't know why it would happen only when the a/c was engaged

[ndottaylor]

Both parked and driving. But it's not all the time.

[Redog]

Me thinks it's the only time he smelt it ;)

[ndottaylor]

do u know much it would cost if it is the "O" ring? and ill have it serviced tomorrow

[Redog]

It cost me about $40. only took 1/2 hour, if that's the problem

That was on the 3400 thou

why don't you open your hood, and take a damn look at the engine bay and see if there's fuel sprayed all over. it's not that hard. look around the injectors, see wetness.

replacing injectors/o-rings/fuel rail crap is not hard at all and can be done very quickly. the hardest part is figuring out how the heck to unplug the wires.

[Redog]

I did find the point of leaking pretty quick ;)

[ndottaylor]

That sounds good... but i dont know crap about working with an "O" ring though. hmmm...

[Redog]

In that case, leave it to a pro.

I know carbs not FI systems ;)

[ndottaylor]

i will do that

[Midgear]

lol.. replacing an O ring is like taking a tiny ass rubber band and putting it around the tip of your finger- its easy as pie.

[ndottaylor]

darnit... i wish i where more mechanically inclined...

Ditto. At least you could check for where the leak is coming if you dont want to repair it yourself. Open the hood, check around the fuel rail, start the car and try to notice if something is leaking somewhere.

Ion, those freaking plugs on the injectors.... UGH! :lol:

[[ion] C2]

srsly that's why i'm not putting my Cobalt injectors in yet
1. don't want to have another epic fuel splash
2. don't feel like figuring out how they come off again

meh i know fuel injection but no clue on carburetors, old school, FI ftw

[ndottaylor]

Ok, so i had my coils replaced a few months back... could it be something with that?

[Redog]

Unless they knocked something loose on the fuel side. The 2 are not connected ;)

If it was a coil probelm, it would run rich or lean and you'd smell it behind the car, not under the hood

[Vinalero]

When I give my car more Throttle than usual (just because I love the way it pulls :lol:) I can smell gas right after for a short period of time. I presume that I must run rich at WOT (which I prefer than running lean). So if his car runs rich, it could smell in the car, no?

Besides, my first car which was a 1986 camaro used to always smell gas in the car. I found out that one O-ring from the manifold was loose and kept getting loose so I was tighting the screws once in a while. I ran a full summer with that car that way, that must have been bad for my brain for sure! lol

[ndottaylor]

I only smell it with air blowing... and then that pos only works on high lol. but i have the blower resistor, i just havent switched it.

And honestly, it may smell like gas only like 3 times a week. I make it to work and by the time i leave for lunch i dont have any issues with it.

lol.. replacing an O ring is like taking a tiny ass rubber band and putting it around the tip of your finger- its easy as pie.

.....or like putting on a condom. :scpimp: Maybe pickup a hooker, see how it's done, then tackle the car the next day!:yahoo:

[Midgear]

^^ I was going to say that, but I figured id keep the conversation somewhat intelligent lol

[cherrington17]

hows your gas mileage? if your losing gas... that would be off a bunch.

[ndottaylor]

hows your gas mileage? if your losing gas... that would be off a bunch.

gas mileage is not so great right now... but its actually in the shop right now so i should know soemthing in a lil bit. I will keep everyone posted

[ndottaylor]

So i got my car back and they found no issues...

I know my friend and i arent crazy... they assured me i had no issues. But they did however pull codes PO440A & PO420A... does anyone know what those are?

[ndottaylor]

The smell of raw gas it a leak as will have to be fixed ASAP.

Don't know how fuel is delivered on the 2.4 though. I had a "O" ring go bad in the fuel reg on the 3400

So i took my car and had it checked... they found nothing wrong. But they did put in my blower resistor... now all speeds work lol... and i have not smelled gas since Tuesday

[cherrington17]

maybe look where your blower motor is... any chance there fuel lines running near that?

(i'm not sure where the motor is, and where the fuel lines are)

[brim]

stay away from the huffin jimmy

I found the problem... it was the fuel pressure regulator... got teh part at autozone for $65 and installed for free... the guys at the shop felt bad bc they didnt catch it so no charge for labor

[deathwish666]

hey ndot how could you tell it was the regulator?...i have this problem right except i only smell it when my heat is on and i want to fix it before it gets to cold to work outside

[Cliff8928]

Most likely fuel was coming out of the vacuum port on the regulator.

[ndottaylor]

hey ndot how could you tell it was the regulator?...i have this problem right except i only smell it when my heat is on and i want to fix it before it gets to cold to work outside

When i would first crank it i popped the hood and could actually leaking oout of the regulator... it was dripping down onto other parts. U will see it if its the regulator

[deathwish666]

thanks...ill have to check that out tomorrow when i can see
