Before you start buying Direct Injectors:
1. Get the Freeze Frame (Fault) History read. Faults possible include indications of a SHORT CIRCUIT or an OPEN CIRCUIT. PCM can't monitor whether the injector is working- only whether the resistance value of the circuit is correct.
2. Verify that it's not a WIRING problem at or near the connector (includes testing the DI separately in many cases).
3. Repair pigtails are available for the harness connectors if required.
4. Avoid "used" DI's. They were removed from some engine for a reason, and very, very few of those reasons are "healthy/good" for the Direct Injector.
