I believe some have plugged the connectors into the wrong things before...maybe you did...nothing personal.
So, maybe therm connector is plugged into the exhaust solenoid...or cps. I believe that can be done.
Does sound like battery...a jump would answer that question.
I don't want to beg, but please, please come to a show sometime!
