getting trouble code 144 and a no start condition. Fuel pumps not working, have spark and injector pulse[kinda]. Fuel/main relay check out but do not seem to get ground signal from computer. Code 144 flowchart at AlldataDIY mentions checking the MFI module [?] and the DI EZ 116K [I think this is the crank sensor] but do not tell me where they are or what they look like. Any ideas on this one?

I found the problem! It was the ECM, apparently ecm's with the last 3 digits of 561 are prone to failure. It is an internal grounding problem. In my case it wasn't grounding the fuel pump circuit.
