Silverbear

Hi all. New member but been reading for years. My fiance has 04 RA SPORTBACK. Died while driving, showed code for CPS..0340 I think.. Replaced, clear code, still nothing. T belt replaced 20K ago, not broken, verified. Realized fuel pump not priming when key on. Fuse in engine bay, #15, iirc, good. But using mmm, getting no voltage at this fuse. Swapped relays under dash, cuz parts store only had 1, still nothing....having troubling finding precise diagram of all relays involved , most discussions are for 3 relay evos....

think they are lowest two on left of under dash fuse box. Took turns replacing with new one, still nothing at fuel pump fuse. No check engine light, and I'm at a loss...

any suggestions ....oh....also took turns swapping the engine bay row of relays next to fuse box, no luck.

Pretty knowledgeable about cars, but really stuck here. All input appreciated.
