MasTach cable, says no signal from ECM???
What gives, I followed the hookup diagram exactly how they illustrated. The diagnosic says the cable is working properly, but it fails to get a reading from the ecm. Anyone experience something similar with the mastach cable? This is kind of pissing me off. I would really like to see what is going on in there
Thanks
Will

What software are you running?
Check the comm port settings, that's usually the culprit.
If your using a USB to serial adapter there could be problems with that as well.
Lot of people having issues with them.

Do you have 10K between pins A & B of your ALDL connector or cable? Your '89 needs this.
