I have been driving around for a couple of days with the gauge. The pressure seems perfect.

But it did die on me at a light today. No miss, no warning, just died. The pressure was sitting at about 3.2 bar and went up to 3.8 as the car died. Then dropped back to 3.2 with the engine off. Car restarted easily, drove off fine.

The surge and the die happened simultaneously.

I have noticed that if you simply shut the ignition off, which it seems would simulate the fuel pump stopping, the pressure stays at about 3.2 and drops imperceptibly to about .8 bar overnight.

Does this ring a bell with anyone?
