I have the exact same issue ( ISO and subaru WRX STI) using OBDuino32k.
I am using a serial LCD (softwareSerial).
I just made a quick test using the serial port and notice that the TX and RX light are blinking... but they are not blinking when I use OBDuino32k.... might be due USB vs No USB.
I have power but iso_read_byte() always return 0 so apparently there is no TX/RX. I tried swapping TX/RX but nothing as well. Anyone can help us?
thanx

I tried both version 127 of OBDuino, and 131 of OBDuino32k with the same results. ISO 9141 fails in initialization (a time out error).
Is the little MCZ33290 chip easy to blow? Everything looks like it's connected correctly, but it's hard to tell. I suppose I will test for shorts and bad connections...
The unit is powered OK from the car (Toyota Matrix 2007), but no RX/TX occurs. Sigh...
