Finally got the shop to figure out the problem. The nefarious fuel pump check valve had failed shut, preventing any fuel from getting to the injectors. I didn't have a fuel pressure gage setup and was doubting my diagnosis that it was a fuel problem because I had replaced the fuel pump and I could hear it run when I grounded the overboost cutout switch. Problem was that the new pump had the wrong fitting on the discharge, so I put the fitting from the old pump on the new pump. The fitting is the check valve.

Should have it back on the road as soon as I get the check valve.

Thanks to all who had offered their encouragement and advice.
