This ^ If your not communicating on CAN low or high then your fuel pump will get nothing via CEM. I had a similar CAN error on my CEM and got the engine started by jumpering the fuel pump relay at the CEM. I'll see if I can dig out any details I might have noted.
Edit: Added Picture
Aston Martin Vantage V8 - Fuel Pump Relay
I see you have two pointed out here. I did replace the one that you have circled.
Okay, so I checked to see what was working and what was not. As far as I can tell, the only thing that is not working would be the tach and the dash communication screen (see pics).
I keep getting that P1000 code, (see pics)
The tach is stuck here, I have never seen it move yet. This is the code I get from the ECM OBD. It will not allow me to clear it.
I wasn’t talking about replacing the fuel pump relay but jumpering it by bridging two of the pins to get power to the fuel pump.
Oh I know, but I had replaced already. It looked like someone had pulled it apart and was not very gentle with it, so I thought I would just replace it. I believe I saw someone, possibly you, take a piece of wire and jump it and it worked. I believe I saw it on here or somewhere like here.
QUESTION: Even if the relay is good, all the fuses are good, could there still be something that could or would not open the relay?
Yes. As I said if the CEM doesn’t send a signal even with a good relay and fuse the pump won’t get power. You can bypass this by jumping two of the terminals using a short wire and two spade connectors.
just wondering did you find out what was the problem for the all odd code ?!
many update please ?
I have same code but car run and drive perfectly
Until two day ago I got fuel system check warning on dash
After research I found some other have a same problem and they replace the fuel pressure sensor
