This tool makes it simple to check fuel injectors in EFI systems to see if they are getting an electrical signal. Just plug in the correct Noid light and start the engine. If the light flashes, there is current flowing to the injector solenoid.
The set includes Noid lights for GM PFI, Bosch PFI, Ford TBI, Geo TBI, GM SCPI and GM TBI systems, plus an injector harness extension so you can check injectors from the driver’s seat.
