'05 V70 n/a Fuel Pump Check Valve Location

" I have the same 5 seconds problem, btw."

Five seconds is the factory setting. Although it seems to me that it should pump again if pressure falls. To compound things, the car will no longer start, even with starting fluid.

Oh, I misread you. I have to wait for like 5 seconds before cranking the engine, otherwise there will be a hard start or no start at all. I read it as stuck check valve that causes fuel pressure loss over time. On a good working car fuel pressure does not go anywhere overnight.

Otherwise no problem with fuel delivery. Pump's duty cycle never goes above 50-51%, even during hard acceleration. Probably makes sense to replace the pump as a preventative measure, but I'm lazy and leaving this problem to future self He must regret that decision in his future, being stuck on the side of road, at night
