Breather fuel line ... ehgine wouldn't start in moist conditions ...
 

I replaced 2 fuel lines (high and low) but didn't replace the third one (breather line) and it's all rusty. Might it cause engine not to start in humid/moist conditions?

I have spent an hour trying to figure out why it wouldn't start (and it happens in humid/moist wheather conditions only). When engine is hot or dry conditions - no prob, it starts like a charm.

I'll be replacing distributor cap and rotor, coil and oxygen sensor.

Any other ideas?

PS: maxima is my winter car and it spent almost all the year long in a heated storage

starting with the cap and rotor is your best bet.

:sprint: if they are a little "vintage" then get new ones...also check wires too.

New wires and spark plugs are already in place.

But back to the original question - could breather line effect it in any way? And what is it for?

Emissions. To keep the excess gas from disappating into the atmosphere

check all of your vacuum lines, esp the big pipe running from the trottle body to the air filter box. Check all of the clamps and sure they're all nice and tight cuz if moisture gets in there, the air sensors will get messed up and won't start the engine.

I used WD40 to get moisture out and it started right away (I let it stay for about 1 hour, of course - I don't want to call the fire dept.).
I guess rotor and dist. cap are my problem.
Thanx or your input anyway! :)
