The strong smell of fuel when car first starts and disappears when car drives

Question edited for clarity, punctuation and spelling.

There are lots of ideas here, but due to the fact you can smell gas, clean the Throttle Body with spray cleaner. It isn't shutting properly. Clean the MAF (Mass Air Fuel) sensor as well.

Could be leaking tank,lines.

I would be considering if the fuel cap is pressurised, if it is then the charkhole canister breather my be blocked . but if it doent start straight away then u must be loosing pressure in the fuel system,does it make a difference how much fuel is in the tank ?it can be the fuel over flow pipe if you fill the tank right up and park it the fuel can swell, it exspands. I hope this is of some help. if not I would like to know were you park it ,how much fuel is in it , is the swell strong inside the car or under the bonnet , in the garage

I had a 91 that smelled of gas because the vent line to the file hole rusted out. It got to where it would leak out on the ground if I opened the nozzle all the way up when filling.

Check the fuel rail that supplies fuel to the injectors. It may be leaking.

dont drive car get fuel line checked

The injectors have o-rings that will wear and cause fuel leak into engine and cause same smoke problem ,but glow plugs are only for engine firing.........you can change o-rings only but if it has lot of miles i would do injectors...
however make sure the fuel rail isnt leaking at injector connection.also check exhaust for excessive heat or noise inside cat.converter if you can shake it.....some come apart inside.....
it would be worth having the engine scanned to make sure 02 sensors are good..they control air/fuel mix and if oxygen level is incorrect it will burn more fuel and sometimes fuel scent but not very bad.

Check under the hood and make sure there are no fuel lines leaking.You should be able to smell it.If you don`t know what to look for the take it to a garage or your dealer and have them look it over.It is not safe to drive if you smell fuel while driving.It could cause a fire under the hood.Good luck.

we call these vehicles exploders.. lol
sounds like a fuel delivery issue, does it throw a check engine warning?

try changing the O2 sensors, bank 1 and bank 2.
