Injector Test Light Kit
If you need to troubleshoot injector problems, this easy to use six piece kit allows you to check for injector pulse on many EFI equipped vehicles. Simply unplug a fuel injector and plug the appropriate lest light into the wire harness connector. If it flashes while cranking/running, you have injector pulse on that injector lead. Includes test lights for GM TBI, Bosch PFI, Ford TBI, GM PFI, Geo TBI, and GM SCPI equipped vehicles.
