[Guest InitialB]

I get a real strong fuel smell when I start up my 93 pathfinder once I drive it for about 10 min it goes away what could this be?

Where is the smell? Front, rear?

[Guest InitialB]

front

Your nose is the best way to find the problem. It could be just the throttle body that smells a little and it is getting trapped under the hood. It could aslo be a fuel line that needs replacing. It could be numerous other things too.

Trace the fuel line both directions from the fuel filter (behind the battery) as far as you can using eyes and nose with the engine off, cold, no key in the ignition. Then do the same thing with the ignition on, but enging not running. Then start the engine and repeat if you still haven't found anything. Does it always do it or only when hot or cold ?

It only usually happens when it's cold, I was told it might just be the mass air meter dumping too much fuel to start the engine. Cold this be the prob?

There is a very short hose between the two fuel injector racks, right at the front of the engine. For some reason this is a very common place to leak fuel when cold. Check there and tighten or replace the clamps if that is the problem.

 

Good luck.

My guess is either the crossover hose like mentioned before or the sending unit. My sending units gasket got to a point it was leaking, changed it out with a new one, still leaked, so it got some silicone. If you open the access panel in the rear cargo floor and look at the top of the sending unit you'll know it's leaking if it looks wet around the sending unit. I would get the sent of fuel in the air after it sat for a little while.

This sounds like it. especially if it's cold out. Just tigthten the clamps and that should take care of it. As posted, it's pretty common problem.

Um, silicone is gas soluable... :o

Yep. I had to use an epoxy based "gas tank repair kit", which is basically an epoxy putty that hardens. My sending unit wouldn't seal either. I put the putty around the hole, then tightened down the screws. NO leaks since.

It was an automotive sealer made for use in gas contact areas, it looked and smelled like silicone . It's been there for 2 years without any trouble or leaks.
