I am trying to find my Fuel Injector relay. In my engine fuse box there are 4 relays that are unidentified and state to look at the manual to ID them. The manual does not show any relays. I have to replace the FI relay. Can anyone tell me what the 4 relays are? I numbered them 1 thru 4. I called my local Honda dealer and they could not figure it out. Thanks

 

What issue indicate the injector relay needs to be replaced?

None of those under-hood relays are the injector relay. Your number 1 is the Ignition Coil Relay, 2 is the PGM-FI Main Relay 1, 3 is the ETCS Control Relay, 4 is the PGM-FI subrelay.

The PGM-FI Main Relay 2 is located in the under-dash fuse/relay box.

The Injector Relay is under the dash and located separately, further up above the under-dash fuse/relay box.
