No injector pulse, bad DME?

Hunting down a no start issue with an '88 3.2. Car fires briefly when starting fluid is sprayed in the intake. I am getting spark, fuel pressure, and 12v on the injector but no injector pulse. I have checked the speed sensor, reference sensor, cyl. head temp sensor, voltage supply, grounds, and everything is in spec. Also tried jumping DME relay (30 to 87 & 87b).

I am testing for injector pulse using a noid light, and have manually grounded the injector pins from the DME connector resulting in the injectors clicking and noid light flashing.

At this point I am thinking it must be something wrong with the DME itself. I have taken it out and am about to start taking measurements. Just wondering if anybody has any other insight into this issue.
