[urq] below 35 degrees cold start problem

[Tom Saltino]

Hey Steve.

Yes, I placed a new stud for a grounding point on the strut tower that is wired directly to the battery in the trunk.  All the old leads on the original wiring harness were snipped off and replaced with new connectors.  I tried to do it right! :-)

I was also thinking that I could replace the starter like you said.  I've got an urS4 starter.  I wonder if that will work with the WX flywheel?
