Look for a major ground that’s not connected. One that’s missed often is between the engine and firewall of the cab. Tester ---

Why would you put a new frame under a 17 year old truck? ---

I’m kind of assuming the frame was rusted out or mangled, but everything else was in decent shape ---

I can’t even fathom how many hours of labor that would take. ---

Step by step. Suggest to get it cranking w/the key in “start”. Measure the “s” terminal at the starter. That’s the thinner of the two wires connected to the starter. It should be 10.5 volts or higher w/key in “start”. Probe b/t the “s” terminal and the starter case. What do you measure? While you are probing down there what voltage does the thicker wire measure?
