Drop me a line, I can probably help if you can manage without your ecu for a few days.

Thx, I really appreciate your offer but I guess now it's a bit too late for that, as the car died properly this time while I was trying to perform a test drive. Afterwards I got the engine running (but very roughly), so the car got carried away by a local towing company, and is now taken to a Honda dealer service.

Now I'll just have to wait for the outcome of their tests. I'll keep you posted once I know something new.

I had a similar problem.

 

Turned out to be a poor electrical connection to the in-tank primary pump.  Once this connection was re-made, everything was fine.

 

you have to remove the rear seat squab to get at the connections at the pump, but its easy enough.

 

Honda tried to renew the fuel filter and also the high pressure pump (they were fixated on this being the problem).  Only when I intervened and asked them to start at the beginning of the fuel delivery chain was the problem then immediately spotted.  Sometimes the simplest possibility is worth trying.

 

Cheers,  Terry

Got a call from Honda today. They weren't able to get out any DTC's either. But when they did the fuel pressure test with HDS, the engine didn't reach the target pressure and stalled. So after all, the main suspect is the high pressure pump.

It's worth serious money.. completely new unit from Honda costs about 2200€. But they also think it's a very hairy price, so they are now seeking for a rebuilt one from Bosch via their contacts. The price should settle around ~1000€.

I know I could find one from Ebay or Japan for a cheaper price, but as it's not 100% sure that the pump is the cause, I'll hand the part purchasing process to them.

Just have to wait and see.

I've had an idtec in with a failing fuel pressure relief valve that had similar symptoms. I would suspect that first. We changed the whole fuel rail from another donor car.

Actually, I also mentioned them about the relief valve, but they seem to be fixated on the hp-pump, just like in scotsgent's case.
