89 accord relay question

so i did my share of looking up what could be causing my friends 89 accord not to get fuel. i just checked out the car. good spark no fuel at all.

i know i changed a relay in my civic.

and im curious the threads say change the main relay. i just want to make sure i send her to get the right one. autozone and napa both show a main relay and a main efi/fuel relay.

please tell me the right one. they area bout 60-70 bux and she's a single mother. might be a stupid question but i know she cant afford buying the wrong one. they both wont return them. and she's a single mother.

thanks guys
