Where is the fuel injection relay located

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. My first question is: why are you asking? What concern are you experiencing? What testing has been done? I am not seeing anything for the "fuel injection" - just "PGM-FI" - a couple relays related. You'll need to obtain a workshop manual and a wiring diagram to determine what is goin on.
