No Fire to Coils

We're working on a Toyota 8FGU45 forklift with a 3.7L 4-cylinder engine. The drive shaft broke and was recently repaired. However, after the repair, the engine won't start. We're getting 12 volts to the coil-on-plug ignition system (no distributor), but there's no spark at the plugs.

We've already replaced both the camshaft and crankshaft position sensors, but we're still not getting a signal (no pulse).

Has anyone run into a similar issue or have any suggestions on what else to check?
