If a JAC HFC4DA1-2C car does not start, has power to the coil, but no spark after replacing the crankshaft sensor, possible issues include:

1. Faulty or incorrect crankshaft sensor installation.
2. Open, short to ground, or short to voltage in the starting motor circuit.
3. Poor terminal connection in the harness (loose, damaged, or mismatched connectors).
4. Damaged wire harness.
5. Faulty ECU or poor ECU ground connection.
6. Intermittent fault not resolved — check DTC history and analyze fault records.

Check connector condition, harness continuity, and ECU ground reliability. Use diagnostic tools to detect signal issues.
