New ALDL cable, but no signal from ECM???
Well I finally got my mastach obd1 aldl the other day, and I loaded about half a dozen different diagnostic programs, and not a single one worked. I ran their supplied diagnostics for the cable, and half the time it passes, the other half it fails?!?! What is going on? When I ran Datamaster software, it tells me that the cable is working, but that there is no signal from the pcm. Anyone experience a similar problem? Thanks

I have a similar problem but not with the reader or software you are using. Mine will not read with using the SunPro/ Actron scanner that is out on the open market. I will try hooking up with winaldl as it seems as most folks have had success with it.

Hopefully there is contact info........yes? If so, let them figure it out. Did your car ever communicate with any other devices/ software? Maybe they forgot the 10k Ohm resistor you may need to get things going. I know they said it is included but you never know.

well the thing is I used to check for fault codes now and then by jumping the a and b terminals. And it worked fine, so I know there is a signal coming from those contacts. I dunno. They said there is a .1% chance of a cable failing in the field after it has passed their initial quality tests. But I tried everything.

Yeah, mine does the ab thing as well. We use a different pin though when trying to access the ECM. Maybe there lies an issue.

I am having a similar problem with my 88 305 TBI. I have tried 2 ALDL cables from Customefis and 2 different USB adapters but neither one is working. With the radioshack USB I get 2 or 3 pieces of data but they are wrong. With the USB adapter from Comp USA I get no data at all. I tried using both WINALDL and Tuner Pro. I was gonna try the moates usb setup, anyone know how well that works, that way I wouldn't need a USB adapter.

moates is supposed to be really good stuff. If I woulda known how straight forward the mastach piece was I would have had my friend make me one. Oh well, lesson learned. I was going to get the moates setup, for tuning on the fly, emulator and burner in one.
