Hondata

I have a 92 Honda Prelude with S300. Car has run before, just all of a sudden fuel pump is not priming/working. I've tested the main relay (continuity on all channels), powered the pump directly (worked), and manually powered the pump and car just cranks. I believe injectors may not be working either.

So, I want to see if this SManager can help narrow down the issue but I've never used it to find problems with my vehicle. Is there a sticky or some sort of guide I can use to troubleshoot where this issue might be?

Open your ECU and inspect the capacitors for leakage. If they have not been replaced yet, have them replaced now. If they have leaked electrolyte onto the board, they may have damaged some of the traces and/or surrounding components.
