I have had this issue. You may have noticed black smoke coming from your tailpipe when you step on it as well. There are two oxegen censors on your exhaust likley under the passenger side of the car close to where the passenger seat is. These will likely need to be replaced. Sometimes you get a check engine light as well when they are bad.

The second hing is to check your filler tube as it may have a seperation and the fumes are coming from there and you can also be leaking fule from the same location.

I can't put gas in the tank

You need to have the EVAP System Diagnosed

That system is mostly at the back of most vehicles
& is used to vent excess fuel pressure from the fuel
tank,burn the fuel fumes under certain programed
conditions & in your case, open the vent valve when
your trying to fuel the vehicle

A bad Vent Solenoid Valve is a possible cause or other
evap issues

You did not mention if you have a dash check light on

That would possibly lead you to a code & maybe even
the part that needs to be component tested

I had a 2000 gmc jimmy. It burns a tremendous amount of gas and strong gas fumes but no leaks what can the problem be?

Sounds like the engine may be getting extra fuel. You need to check your fuel pressure and see what is up. It may be your fuel injectors. Try to get a code if check engine light is on. Is it stalling any? If not, you need a code. Check all fuel components. If you have a question, contact me. I am here to help in anyway I can.

AWESOME a real camaro problem.
strong odor of gas because the gas isn't getting burned
caused from backfire. backfiring because the spark isnt sparking when its supposed to.
problems could be bad spark plug wires , bad plugs , bad ignition parts.
your gonna need to check wires for bad spots, check ignition coils and stuff like that. if all that stuff is ok, then your problems have to do with inside the engine. jumped time etc.

Excessive black exhaust on 2003 GMC Sierra Duramax Diesel.

This is what i would try (cheapest first) redexe/wyyns
injector cleaner,double dose,then i have put 1gal gas in 10gal diesel to increase burn temp (you may encounter a hot start problem temporarilly)then if still smoking, get a compresion check on the engine(this will tell you volumes)
by the way the NATO tanks put in 1/3 gas in diesel to stop it freezing in arctic conditions.any more than 1/3 can result in problems.

A strong gasoline smell but no appearent leak, what can be the cause?

fuel systems have a vent or a purge solinoid which will purge the fumes back to the tank which can in some cases send excess fumes to the vent
check to make sure you have a good gas cap and the perge is working

1997 GMC Jimmy, Won't go into reverse,but all other gears work,ok.

Check the automatic transmission fluid color.

It should be lite pink and there is ZERO odor of burn friction material.

TOP OFF is it's low on ATF


Have some one the check on the reverse light when you put the truck into the reverse gear.

NO reverse lights then the neutral safety is falling.


Check for free play on the gear lever. Pay close attention on the transmission end.

USE clear to remove excess dirt.


Inspect transmission pan and the floor for ATF leak.


Please rate my answer if it's helpful to you.

Our jimmy burns $20 - $25 per day in gas and we only travel 14 miles to work and school each way. a mechanic said our fuel filter needs to be changed. can we do it ourelves?

You can but you should purge the system first as not to get a gas bath when you break the lines loose, or break the lines loose just a little to relieve the pressure and have a pan to catch the gas until the pressure is off. Myself i can't understand how a fuel filter could make it use excess gas, i would think it would be the other way because if the filter is pluging up( what usely happens) less gas would be geeting thru and it would run bad or in some cases not at all. It won't hert to chg. it chanses are it needs one anyhow. My advise would be to get another opinion you might have something else going on hear.

I have a 1995 GMC Jimmy,rough idle, carbon smell, strong gas smell coming from the left driver side, check engine light is on. Has a hard time turning on...Any suggestions?

My 94 Jimmy had similar problems, until the dirty EGR valve was replaced. We tried a million things, first. But the improvement with the new EGR valve has HUGE.

98 gmc jimmy smokes real bad and burns lots of gas

The smoke is probably a black smoke from burning excessive fuel. That fuel injection system has seperate plastic runners going to each cylinder inside the intake manifold, I think it was nick-named the spider, they go bad and need to be replaced. Problem could also be the fuel pressure regulator, I think it's also under the intake manifold. The bottom line is that you have to remove the intake and look for your problem.
