Engine no start after ECM put back in - ZR-1 Net Registry Forums

I was having some issues with my engine after getting a code 31. After doing the diagnostic, it indicated the ECM as the culprit. It started and run ok before I took it out. I sent to it to Haibeck and had it overhauled. According to what he told me, after it was done, it worked great! He put it in a ZR-1 and it worked flawlessly. When he shipped it back to me, I was tied up with work and moving. Finally, got the chance to install it and I started the engine or so I thought. Engine turned over no light off. One thing that I noticed was the lack of fuel pump noise when I tried to start the engine. I replaced the fuel pumps about a year and a half ago because the sending unit broke. Tomorrow, I'm goin to hook up my fuel gauge and check to see if that is actually the problem. Is there any other thing that I can check into? I do have the manuals for the car. I appreciate any help that you guys can do.
