144 Error Code on 940T; Bad ECU?

My 940 has been running great lately, except for stalling last night. It stopped running suddenly and is now posting a 144 code on port 6, showing a "No load signal from fuel injection system" issue. It also had a 121 from port 2, but that code isn't showing up after checking the MAF plug.

After reading the posts concerning this 144 code I decided to look into it myself. I've investigated about this code and ran some diagnostics based on what the posts told me. The posts said that typically this code is tripped from a lack of power coming from the 87/1 spade on the injector relay. I replaced the injector relay with a known good one, checked the voltage at the fuse panel and followed the power to the ECU.

I thought I had a spare ECU, but can't locate it. I'm going to take a look around the local junkyards for a compatible ECU.

In the meantime, does anyone have any other ideas of what could be wrong? At this point I'm somewhat stumped and could use some help.
