LOW miles
( 87K) Gas engine</font>
<br>
<br><font size="2" face="sans-serif">When it runs, it is flawless. Great
idle, lots of power, no issues. Kept in heated garage. Always
on a battery tender.</font>
<br>
<br><font size="2" face="sans-serif">About 6 months ago (maybe longer as
this truck is rarely used.) when I would first start it, it would
idle way too low and stall. I few minutes of warm-up, and it was
fine.</font>
<br>
<br><font size="2" face="sans-serif">Then, this past month, I had to move
it to one of my out buildings for about 3 weeks. The building has
lots of moisture (it will NOT stop raining and now snowing here.)</font>
<br>
<br><font size="2" face="sans-serif">I went to start it up and it wouldn't
start. Engine turned over fine, sounded normal, but it wouldn't start.
After I tried a few times, the engine would 'diesel' when I
stopped cranking. </font>
<br>
<br><font size="2" face="sans-serif">I tried some starter fluid and it didn't
change anything (so I thought no spark.) Battery was on a 'boost
starter' plugged in the wall. Gas smell coming out of tailpipe.</font>
<br>
<br><font size="2" face="sans-serif">Checked spark, all good. Under
the hood seemed dry (there was no condensation or anything) but the building
had a wet floor.</font>
<br>
<br><font size="2" face="sans-serif">After some wrangling with a tractor,
fork-lift, and a few new vocabulary words, I got it onto the main
garage where I let it sit over night with the hood up.</font>
<br>
<br><font size="2" face="sans-serif">So I tried it today and it started right
up. So this is clearly an issue with the moisture. My question
is, where do I start to troubleshoot? I can't predict it being moist
in the other garage (and when it's there, it's away from all my tools etc.)</font>
<br>
<br><font size="2" face="sans-serif">ODBC tool has no codes.</font>
<br>
<br><font size="2" face="sans-serif">Any ideas on how to fix this? I'd
hate to be stuck on the side of the road because of rain or something.
</font>

Thanks!</font>
