OTC 3398 Fuel Injection Pulse Tester, 4.9 x 2 x 8.1 inch
- The OTC 3398 Fuel Injection Pulse Tester is a diagnostic tool for checking cylinder balance by firing individual fuel injectors in selectable pulse durations; it includes a wiring harness adapter and instructions from OTC Tools/Bosch. It is intended for use with gasoline-fuel electronic injection systems not diesel.
- Features:
- Provider of three pulse modes: one pulse of 500 milliseconds; 50 pulses of 10 milliseconds; 100 pulses of 5 milliseconds allows diagnosis of injector consistency issues.
- Selectable 1/2-second increment triggering of individual injectors enables cylinder balance testing.
- Power and output indicator lights visually confirm test activation and pulse output.
- Includes wiring harness adapter and instruction manual ensures correct connection and safe operation.
- Designed for use on vehicle battery as power source portable and usable in typical automotive service conditions.

Q: What vehicles are compatible with the OTC 3398 Fuel Injection Pulse Tester?
A: It is compatible with most gasoline vehicles fitted with electronic fuel injection systems; it should not be used on diesel injectors. Check the vehicle service manual to verify it uses a compatible injector type.
Q: How do I use the different pulse modes?
A: The tester allows three pulse durations (500 milliseconds single pulse; 50 pulses at 10 milliseconds; 100 pulses at 5 milliseconds) to simulate injector firing; use longer pulses for coarse testing and shorter pulses for checking fine responsiveness and leakages.
Q: Is an Includes section required for the OTC 3398?
A: No, it is not required because this product is a single tool with non-distinct components beyond the harness adapter and instructions which are standard accessories rather than separate distinct items.
