99 Cirrus Refuses to Start on (Very) Rainy Days

My 99 Cirrus has been pretty reliable since I bought it new. This year,
however, I have had to replace one of the speed sensors (went into limp
mode) and the crankcase position sensor [we are at 119,000km] . This fall,
whenever it is cool and very rainy it refuses to start or dies abruptly at
the first or second stop sign (within 1 km of home). No codes, of course. No
problems once it starts to warm up.

If I plug a consumer code reader into the diagnostic port it comes up clean.
Two dealers get the same after an extensive diagnostic session. Guess their
service bay cannot reproduce the conditions of a rain-soaked driveway. Oh,
there is gas in the tank...

Any thoughts?

Thanks,

Just one thought right now, what engine does the Cirrus have?

The 2.5l v6. It is the LXI package...

 

dist. and or cap and coil

 

Sure they can produce the rain soaked driveway, I call it a garden hose and
a very useful tool for simulating rainy days and overnight drivability
problems. You may have a distributor cap that is allowing moisture to
accumulate over nite causing this..
But also, There is a TSB out on your vehicle that may pertain to your
problem. It requires replacing the EGR valve with an updated one. It would
have nothing to do with wetness but will cause problem in the morning or
long crank times when the engine is extremely hot and setting for awhile.
