sounds more like the main relay if his electrical goes out.

the main relay is a repeated TSB recall for 4g ludes
i have changed mine already and i also have a 92 Si, originally came with the 2.3L.

its located under the dashboard basically above your clutch pedal. its a box about the size of a cigarette pack. the cover of the relay is bolted to the dash, you can get the relay out of the cover but either way its a bitch to replace. i got mine from honda here

its #12 in the illustration

good luck - get a helms
