Honda Greiz Engine Stalling Fuel Volume Regulator
Summary of the thread
A 2018 Honda Greiz with 246,256 km exhibited engine stalling, reduced power, and a check engine light, indicating a potential fuel volume regulator issue. The symptoms suggested a problem with the high pressure fuel pump, which can lead to incorrect fuel pressure delivery. It was advised to have a professional handle the repair due to the complexity and risks involved with fuel systems. Ultimately, the issue was confirmed to be a defective high pressure pump and fuel volume regulator, which were replaced, resolving the problem.

Yeah, the fuel economy has definitely taken a hit! If it is the high pressure pump, is that something I can tackle myself, or am I better off taking it to a mechanic? I'm fairly handy, but fuel systems seem a bit intimidating.

Fuel systems are intimidating, and with good reason. Given the high pressures involved and the potential for serious damage, I'd strongly recommend getting it checked by a professional. I messed with a fuel pump once, and trust me, the potential cost of getting it wrong far outweighs the labor cost at a workshop. You could easily make things worse and end up with a much bigger bill.

Thanks for the advice! I took it to the workshop, and you were spot on – it was a defective high pressure pump. The fuel volume regulator was gone too. Cost me 1510€ to get it all fixed. Ouch! But at least it's running smoothly again. Appreciate the help!

Sounds like a high pressure pump issue. I had similar symptoms on my old Civic – check engine light, rough idle, and loss of power. Is your fuel economy also worse than usual? I’d suspect the pump is failing to deliver the correct fuel pressure.
