Fuel Injector Resistor: Testing

WARNING: This page is about a different car, the 2001 Acura NSX-T, 2001 Acura NSX, 2000 Acura NSX-T, and 2000 Acura NSX. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect the fuel injector resistor connector. Fuel injector resistor is in right side of engine compartment. See Fig 1 .
