Strong gas smell when starting
Tried searching, but does anyone know if it’s normal for our Z’s to have a strong gas smell when starting after the car has been sitting for a couple of hours?

Any mods?
HFC and test pipes can make a difference. Cats burn off any raw fuel that gets thru to the exhaust. Once they heat up, that is. Take them out of the system with test pipes, or reduce their effectiveness with High Flow versions, and a gas smell can be more apparent. Kirk B. |
weird...you need to make sure that the fuel hose didnt come of the pump housing, by removing the small resting panel behind pass seat, after that remove the cushion, there you will find the access to the gas tanks fuel pump, check the fuel hose connection, make sure its all the way in and if there are fuel traces around, if its all the way in and no fuel traces, you need to follow the smell or fuel line to find the leak.
MAKE SURE THAT YOU DO THIS IN A WELL VENTILATED AREA!!!! |
Engine Breather pipe/joints...check for cracks or broken joints.

No mods, been smelling it for a while now. First thing i checked was fuel pump since it was changed out a few months back and all is well there. Thought maybe leaky fuel injectors, but wouldnt that cause the car to be hard to start? Doesnt have an issue starting, just really strong fuel odor for about the first minute after starting the car.

One thing popped in my head when I read about fuel pump install;
Another member used screws that were too long & caused a problem. |

With the aid of a helper or two, you should be able to locate where the smell is coming from. If smell is coming from exhaust, probably an injector.
If the location can't be determined using noses, you can rent an explosimeter. |

Thanks for the responses guys, i will double check the fuel pump hoses but i know for 100% sure that the screws that were used to install the fuel pump are the originals. The fuel smell itself didnt start till a few months after the new fuel pump was installed. Not 100% sure without a second person helping, but the smell does seem to be coming out of the tailpipes. Guess it’s a good thing i picked up a fairly new set of injectors off of a fellow member here a while back lol

Wasn't there some nissan tech article on the breather hose getting plugged? I think you can take your nissan in and have them check it for free.
