S&G Tool Aid Fuel Injection and Ignition Spark Tester Kits

S&G Tool Aid fuel injection and ignition spark tester kits help you quickly diagnose "no" start and engine miss conditions in the electrical fuel injection and spark plug circuits, as well as analyze rough running engines. The kits consist of a Noid light set to test electronic fuel injection signals and an in-line Ignition spark checker to trouble shoot the ignition system by showing a duplicate view of the ignition spark. The Noid lights can be used to check Bosch PFI, Ford TBI, Geo TBI, GM PFI, GM SCPI and GM TBI systems.
