Default OBD Exhaust Connection Failure

Hi, picked up an old 1998 Dodge Ram 1500 5.9l about a month ago.. it's got a lot of miles and so far, a lot of problems

So far I've replaced the battery, the water pump, the tensioner pulley, the water return hose, the lower radiator hose, all the ball joints and the tie rods, welded the muffler back on, and solved one parasitic power drain.

I'm trying to pass safety and emissions testing, but the emissions shop's OBD device won't connect to the computer. I went through all the fuses, found one (12 I think) that was blown. Replaced that fuse, went to Autozone, their OBDII sensor connected fine. Then I went back to the emission's shop and their device still won't connect.. I'm a little lost what I should do now and I've googled for an hour now and am not finding anything helpful. Do I need to replace the ECM? I don't think it's a power issue since the Autozone meter worked.

Anyone have any ideas?

Thanks in advance!

Moevin

No one?

Any stabs of ideas? Conjecture?

I've had the battery out a lot lately, would it not connect for emissions if I hadn't driven enough for the monitors to set? Is there a place I can check for power to see if the ECM is faulty?

Can you try a different emissions shop? If the autozone OBDII scanner can connect up it doesn't sound like your end is the problem to me.
