I would look carefully at the spark plugs and plug wires , as a general
thing that needs to be considered and checked ..
and often , especially spark plug wires, are kept in service a really
long time, commonly.
also .. when I have had 1.9 wbxr weird heebie geebies about failure to
start ..
in the end it turned out to be the Idle Stabilizer. You really should
have at least a known good tested spare , or new one in your parts
stash. I do not believe in running a 1.9 wbxr without one, though it
will run with that part bypassed.
also ..connection at the side of the distributor
and the hall sender in the distributor ..
Those are 25+ years old usually . It's really good to have a spare
known good distributor.
A poor connection at Temp II can trick you, check that extra carefully.
for sure, to grasp the deeper implications of this statement 'It's just
a blockage or leakage of fluids or electrons.'
and many people do not automatically realize 'fluids' are also gases,
such as vacuum , exhaust, air, etc.
cleaning contacts everywhere as suggest in the other post is always a
good idea.
grounds too of course.
My hunch is it needs more careful and thorough visual inspection of
every componnet and connection in the EFI and ignition.
heck ....put a timing light on it and see if it's flashing when you try
to start it on a cold damp morning.
come up with a few testing trickslike that.
what is the fuel pressure, for example ?
I just pulled THE WORST amount of rust out ofan 85 vanagon fuel filter
you could imagine .
One of those small square fuel filters ..had about a whole thimble full
of red rust particles in it .
Doesn't sound like you have that going on ..
everything needs to be checked and considered until you find 'it' or
'them' ...the bloackages or leakages.

> 84 Vanagon, 1.9. I used to think the problem was temperature related, but think it is moisture/dew point. In the morning with dew on the windshield, the van won't start--starter engages and the engine just grinds. I'm thinking there must be some kind of short or current drainage that is causing this. Later in the day, the van starts fine. I've checked the grounds and they look good, checked all the electric connections, swapped AFM's, changed the coil, fuel pump is new and connections seem solid. Temp II sensor is new and connection checks. Has anybody experienced any similar type problem or suggest troubleshooting?
