Gas smell from engine?

[hondakiller44]

On my 93 GT I am getting a strong gas oddor when i first start my car and when it is at idle. What should I be looking at? I think it might be a injector stuck open. How would I check to see if on is stuck?

thanks

Take a long wood dowl and put it against the injector, then put your ear to the other end of the dowl, you can then here if the injector is opening and closing.

I would look at your charcoal canister and make sure the vent tube from your gas tank isn't unhooked or cracked.

My vote too...

where abouts is the charcoal canister? I assume its near the gas tank but where exactly and what does it look like?

The charcoal canister is right underneath your CAI or stock air box on the pass side, mounted to the underside of the frame. There is a line that runs from your gas tank to the canister, then from the canister to the upper intake. The line from the canister to the intake has a valve on it. Pressure is vented from the tank back into the intake via that valve with vacuum. Does your gas tank ever vent pressure when you take the gas cap off? It shouldn't if the canister is hooked up and working correctly.

Check your fuel lines as well. You could have a bad O-ring in one of them.

come to think of it i think i have heard a pressure release a few times when i take the cap off.(like opening a can of coke lol) Does that mean the charcoal unit is bad or there is a bad line or disconnected line?

thanks

The vent line for the tank is probably capped or plugged near the charcoal canister.

It can be an issue with the cannister and the cannister ancillaries, or simply a crimped vent line to the cannister from the tank (even old school stuff with no Char box would hiss if the vent line was pinched). vacuum in the tank is not great.

Good luck.

ok I will check my lines for obstructions.

thanks guys

oh yea will a plugged or malfunctioning charcoal box have any effects on how your engine will run? lean,rich, lack of power etc.
