Alright, I'll remember that.

Ugh, I don't like the sound of that already.

Probably a weak connection then.  The passenger works fine, but is
missing a bulb, and the driver side seems to work when it wants to.
Usually before or after a rap against the driver front.

I left the battery in the square overnight, and came out this
morning and started it up.  It fired on the first try, didn't
die or sputter.  Sounded beautiful.  While looking for the 10mil
wrench (have to put the battery back in the bug). It began
coughing and choking.  I didn't check it any further, just cut it
off and pulled the battery. 

This FI system really is not impressing me right now.  So far
every problem that was erratic and hard to figure out came
from the FI system.  Usually part of this lousy wiring harness.
The only upside is that I'm getting better at experimenting
and tracing down problems.

Next on my list is to check the fuel pressure.  If that checks
out fine, then I'll be more than slightly frustrated with this
FI system.

Thanks for your help,
Jon
