Check your fuel pressure, if low or no pressure, replace fuel filter first. My guess is the fuel pump and sensor are bad. You may also want to see if your getting spark, but I don't think bad plugs would make has gage jump around, but if they are not sparking correctly they will allow gas to flood the motor and that's when you get the gas smell

You need to check the fuel press, the test port in on the rail, also run a code test on the ECM/PCM, this checks for trouble codes and also lets you know the computer is working if it tests ok.

SOURCE: what will cause a strong gas smell after turning off engine

Check the fuel cap gasket to be sure it is not torn or worn. After that check the vent hoses that run from the fuel tank to the charcole canister located somonwhere under the hood. Is the smell stronger under the hood or toward the rear of the car? If you cannot find the problem, a fuel leak is dangerous and should be attended to ASAp by somone that has the experience to repair the problem
Good Luck

SOURCE: car is jerking engine light is flashing and smell gas

With modern cars it is bad when the engine light just comes on and the vehicle does something very different. It should not be driven. If the car is smelling of fuel and jerking it is because it's miss-firing (i.e. one or more cylinder is not getting spark but is getting fuel). This can be anything from electrical/electronic to mechanical like a broken rotor cap (as an example). The good thing, is that the light is coming on and a mechanic can check the ECU for error codes. Alternatively, you can buy or barrow one your self and check it out on your own (I think even certain auto-part stores will check it for you as long as you get in the zone;). 1996 is a good year for that since that is when OBDII started and all vehicles started using the same port to check for issues.

Sounds like you have a ground problem, i doubt its in the sending units as both gauges are acting strange work, seeing that electricity likes paths of least resistance one gauge could be grounding through another. Bad grounds wreak havoc on electrical systems.

SOURCE: strong smell of gas inside and outside the vehicle

there can either be a hole in the tank or in the carbon filter of the fuel system. or a bad seal on a hose leading to that Carbon filter. But assuming that the smel is stronger at the rearside, it is more likely to be an issue around the gas tank. Maybe if the belly 'sat' on a rock it could be even on the upper part of the tank(but not that likely, rather a joint again)

rate please

My first thought would be: If you repaired an emissions hose, take the car back to Auto Zone (or another parts supplier) and let them tell you what code comes up now. You eliminated one problem, now you have to find another.
I wouldn't do a fuel pump without more information.

If your not getting the MIL- engine light coming on and you can smell gas and you had the fuel pump replaced. I would sespect the electronic ignition module of being intermintent. It wouldn,t necessarily show as an engine code and would make it so the vehicle would run find one munite and not run the next The other thing you could check is the fuel filter however i can,t see a mechineic not changeing this with the fuel pump

White smoke and a smell of fuel


The white smoke is from anti freeze. The smell of gas in your oil is probably from the same cause. I do beleive you did not clean the milled ares good enough before installing one or both of your gaskets. Just in case you did loosen one of the head bolts up for any reason....One bolt I do beleive on the right front bank of this engine has to be also sealed before re enstalling it for coolant will pass through it if not sealed

1995 chevy blazer running bad shooting an EGR code,


Hook up a fuel pressure guage. Now with the key on and engine off does the fuel pressure come up fast and hold steady at a fixed value?
