DPTOOL Noid Light Test Kit — Injector Pulse Tester for GM PFI/TBI/SCPI, Multec2, Ford TBI

Effortless injector troubleshooting on demand

The DPTOOL Noid Light Test Kit offers a straightforward way to verify whether each injector is receiving an electrical signal from the vehicle’s control module. Using the included lights, you can observe the presence or absence of a signal as you crank the engine, helping you rule out electrical issues quickly and without guesswork.

Designed for real-world use, the kit guides you from setup to interpretation with practical, non-technical language. The visible LED pulses provide immediate feedback, so you can confirm a healthy signal path or pinpoint where a fault might be occurring in the fuel delivery circuit.

What’s inside the kit

• Eight Noid lights with a broad set of terminal configurations to fit common GM PFI, TBI, SCPI, Multec2, and Ford TBI connectors.
• IAC (idle air control) tester to check idle control valve wiring and operation.
• Extension cable to reach hard-to-access connectors while you sit in the driver's seat.
• Durable portable case for organized transport and on-site testing.

Key benefits and real-life use cases

• Quickly verify injector pulse by watching the Noid lights flash during engine cranking, which can speed electrical diagnostics.
• Reduce guesswork when diagnosing fuel delivery or wiring issues, potentially saving time in busy workshops or at home garages.
• Works across a wide range of vehicles thanks to multiple terminal options, making it a versatile addition to your toolbox.
• Keep connections organized and accessible with the included IAC tester and long extension, useful for engine bays with limited access.

How to use

• Attach the Noid lights to the injector connectors and, if present, the idle air control connections.
• Crank the engine and observe the lights. A normal pulse is indicated by a flashing pattern; no flash may require inspection of wiring or ECU signals.
• If any light remains constant or behaves unexpectedly, consult wiring diagrams and ensure proper seating of connectors.

Compatibility and care

The kit packs a comprehensive range of adapters to match many plugs encountered on GM and Ford engines, plus extensions for easy reach. When not in use, store the kit in the portable case to protect the LED modules and connectors.
